The OMAP5 HW supports directing DIGIT channel to DPI output, but the
driver doesn't support that. However, we have marked that configuration
as possible in the dss features, so in certain cases the driver tries to
use that configuration, leading to broken display.
Fix the problem by allowing DIGIT channel to go only to HDMI output.

The sys_copyarea() function performs the same operation as
cfb_copyarea() but using normal memory access instead of I/O
accessors. Since the introduction of sys_copyarea(), there
have been two fixes to cfb_copyarea():
- 00a9d699 ("framebuffer: fix cfb_copyarea")
- 5b789da8 ("framebuffer: fix screen corruption when copying")
This patch incorporates the fixes into sys_copyarea() as well.

CVT v1.1 spec says: "the vertical front porch shall in all cases be
fixed to 3 lines". The code in fbcvt.c instead sets the _back_ porch to
3 (plus margin).
After swapping cvt.v_front_porch and cvt.v_back_porch the resulting
timings were in line with CVT timings in VESA DMT spec.
The bug seems to be more than 9 years old, but I presume it has not been
noticed as usually the video timings come from the EDID or from the
timing tables in fbdev, and probably swapped values for vfp and vbp work
fine for most of the displays.

fbmon may generate mode timings that are out of spec of the monitor.
eg DELL U2410 has a max clock 170mhz but advertises a resolutions of
1920x1200@60 in its Standard Timings using 2byte code of D1 00.
When this is looked up in the DMT table it gives it a 193mhz clock.
Although the DELL monitor supports 1920x1200@60, it can only run with
reduced timings at 154mhz or DMT id 0x44 which has no STD 2byte code.
This patch checks to see if the mode can be supported by the monitor
by comparing against monspecs.dclkmax.

Pull x86 mm tree changes from Ingo Molnar:
"The biggest change is full PAT support from Jürgen Gross:
The x86 architecture offers via the PAT (Page Attribute Table) a
way to specify different caching modes in page table entries. The
PAT MSR contains 8 entries each specifying one of 6 possible cache
modes. A pte references one of those entries via 3 bits:
_PAGE_PAT, _PAGE_PWT and _PAGE_PCD.
The Linux kernel currently supports only 4 different cache modes.
The PAT MSR is set up in a way that the setting of _PAGE_PAT in a
pte doesn't matter: the top 4 entries in the PAT MSR are the same
as the 4 lower entries.
This results in the kernel not supporting e.g. write-through mode.
Especially this cache mode would speed up drivers of video cards
which now have to use uncached accesses.
OTOH some old processors (Pentium) don't support PAT correctly and
the Xen hypervisor has been using a different PAT MSR configuration
for some time now and can't change that as this setting is part of
the ABI.
This patch set abstracts the cache mode from the pte and introduces
tables to translate between cache mode and pte bits (the default
cache mode "write back" is hard-wired to PAT entry 0). The tables
are statically initialized with values being compatible to old
processors and current usage. As soon as the PAT MSR is changed
(or - in case of Xen - is read at boot time) the tables are changed
accordingly. Requests of mappings with special cache modes are
always possible now, in case they are not supported there will be a
fallback to a compatible but slower mode.
Summing it up, this patch set adds the following features:
- capability to support WT and WP cache modes on processors with
full PAT support
- processors with no or uncorrect PAT support are still working as
today, even if WT or WP cache mode are selected by drivers for
some pages
- reduction of Xen special handling regarding cache mode
Another change is a boot speedup on ridiculously large RAM systems,
plus other smaller fixes"

On Atmel AT91, the conversion to device tree is now considered complete,
and all machines that were not already converted in 3.18 are assumed to
be unused and dropped by the maintainer.
All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.
There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the platform
itself is not "multiplatform"-enabled, but both issues are going to be
taken care of in the 3.20 cycle.
This is split out from the other cleanups purely based on the size
of the branch.

struct dsi_clock_info represents the clocks handled by the DSI, mostly
PLL related clocks. In an effort to create common PLL code, we need to
remove all the non-PLL items from dsi_clock_info.
This patch removes LP clock related fields from dsi_clock_info, and
creates a new struct dsi_lp_clock_info for holding clock info for the LP
clock.

The DSS PLL has support to power on the PLL's highspeed clock output
and HSDIV output separately. In practice both need to powered on, as in
most OMAP's that's the only working configuration. We already do that in
dsi_pll_init(), by overriding the passed arguments so that both are
always powered.
Simplify the code by removing the support for choosing which outputs to
power on.

At the moment we have two functions to wait for the HSDIV clocks to get
active, dsi_wait_pll_hsdiv_dispc_active and
dsi_wait_pll_hsdiv_dsi_active. Instead of such inconvenient functions,
let's just make sure that the hsdiv clocks are active after the pll has
been enabled.
This patch adds code to dsi_pll_set_clock_div() to wait until HSDIV
clocks are active.

Register DPI outputs, and assign the port_num to them as specified by the
'reg' property in the DPI ports in DT.
To support multiple DPI instances, dpi_get_channel needs to take the DPI
instance's port number to get the corresponding channel. Make it take this
argument. We just pass 0 in the non-DT path, since we don't support multiple
instances in the non-DT case.

In omapdss_of_find_source_for_first_ep, we retrieve a source endpoint's DT node,
and then see what omapdss output has the matching device_node pointer in
omap_dss_find_output_by_node.
For all DPI and SDI outputs, the device_node pointer is set as the parent's DSS
device_node pointer. If the source is one of these outputs, the above method
won't work.
To get the correct output for ports within DSS(and in other cases in the future,
where multiple ports might be under one device), we require additional
information which is exclusive to the output port.
We create a new field in omap_dss_device called 'port_num', this provides port
number of the output port corresponding to this device. When searching for the
source endpoint in DT, we extract the 'reg' property from the port corresponding
to the endpoint source. From the list of registered outputs, we pick out that
output which has both dev->of_node and port_num matching with the device_node
pointer and 'reg' of the source endpoint node from DT.
For encoder blocks(the ones which have both an input and output port), we need
to set the port_num as the 'reg' property for the output port as defined in the
DT bindings. We set port_num to 1 in the tfp410 and tpd12s015 encoder drivers.

The init/uninit port functions are used to set up the DPI and SDI outputs under
the dss platform device. A 'reg' property is used to determine the port number
of the output. This tells us whether the port is DPI or SDI for OMAP34xx DSS
revision. For other DSS revisions, we only have DPI outputs under the dss
platform device.
For multiple DPI output instances(introduced in DRA7xx DSS), we will use the
the port number to specify which DPI output instance is being inited.
The current functions work fine if there is only one DPI output instance in
DSS. For multiple DPI instances, it would get complicated to figure out whether
port number was used to specify whether the output is SDI, or another DPI
instance.
We create a list of port types supported for each DSS rev, with the index of the
port in the list specifying the port number of the output for that DSS revision.
This allows us to have a more generic way to init/uninit ports within DSS, and
also support multiple DPI ports.
We make the uninit_port functions iterative since we will have multiple DPI
ports to uninit in the future.

DPI and SDI ports are backed by only one parent DSS device. We don't have a
corresponding platform_device for ports under DSS. In order to support multiple
instances of DPI, we need to pass the driver data pointer through the DPI port's
private data ('data' member in device_node struct).
dpi_init_output/dpi_uninit_output are untouched and only used for non-DT case,
these are called when the DPI platform device probed/removed. These funcs will
be removed when non-DT mode is removed.
dpi_init_output_port/dpi_uninit_output_port are created and used for the DT
path, called when DSS inits/uninits it's ports. These new functions retrieve
the dpi_data pointer from 'port->data', and not from the platform device's
data(pdev->dev) like in the non-DT path.
We add some code in dss_uninit_ports() to pass a pointer to the DPI port in
dpi_uninit_port().

Allocate driver data(dpi_data) for each DPI instance. It's allocated in
omap_dpi_probe() when DT isn't used, and in dpi_init_port() when DT is used.
The dpi_data struct instance is no longer global. In the case of DPI ops, it's
retrieved from dpi_get_data_from_dssdev(). 'dssdev' passed by the connected
encoder/panel driver is a pointer to the 'output' member in dpi_data, and thus
can be used to get the DPI instance's driver data. In the case of probe/ini_port
functions, it's set as DPI/DSS device's private data embedded in the
platform_device struct.
Having dpi_data as private data of the platform device will not work for
multiple DPI instances in the DT case. This is because there is no corresponding
platform_device for DPI or SDI, they exist only as ports under the parent DSS
platform_device in the DT case. The DPI port's private data('data' member in
device_node struct) will later be used to store dpi_data.

This method won't work if we want the driver to support multiple DPI instances.
Create struct dpi_data, and pass its pointer to functions which need to use it.

The PLL settings are committed by setting GO bit, which is then cleared
by the HW when the settings have been taken into use.
The current PLL code handles this wrong: instead of waiting for the bit
to be cleared, it waits for the bit to be set. Usually, the bit is
always set, as the CPU has just set it before. However, if the CPU takes
enough time between setting the GO bit and checking it, the HW may
already have cleared the bit and this leads to timeout error.
Fix the wait to check the bit properly.

- Increase the default ARCH_NR_GPIO from 256 to 512. This
was done to avoid having a custom <asm/gpio.h> header for
the x86 architecture - GPIO is custom and complicated
enough as it is already! We want to move to a radix to
store the descriptors going forward, and finally get rid
of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated
by Abdoulaye Berthe. It is not accepted by the system that
the removal of a GPIO chip fails during e.g. reboot or
shutdown, and therefore the return value has now painfully
been refactored away. For special cases like GPIO expanders
on a hot-pluggable bus like USB, we may later add some
gpiochip_try_remove() call, but for the cases we have now,
return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI
GPIO library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle
also threaded, nested interrupts and set up the parent IRQ
correctly. Switch STMPE and TC3589x drivers to use this

Merge tag 'gpio-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO changes from Linus Walleij:
"This is the bulk of GPIO changes for the v3.18 development cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This was done
to avoid having a custom <asm/gpio.h> header for the x86
architecture - GPIO is custom and complicated enough as it is
already! We want to move to a radix to store the descriptors going
forward, and finally get rid of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated by
Abdoulaye Berthe. It is not accepted by the system that the
removal of a GPIO chip fails during eg reboot or shutdown, and
therefore the return value has now painfully been refactored away.
For special cases like GPIO expanders on a hot-pluggable bus like
USB, we may later add some gpiochip_try_remove() call, but for the
cases we have now, return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI GPIO
library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle also
threaded, nested interrupts and set up the parent IRQ correctly.
Switch STMPE and TC3589x drivers to use this registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so that also
GPIO expanders that block but are still not using threaded IRQ
handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the "DSP GPIO"
found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated from and
MFD cell (platform device).
- Incremental feature improvement in the Zynq, MCP23S08, DWAPB, OMAP,
Xilinx and Crystalcove drivers.
- Various minor fixes"

When the PM domain containing the HDMI hardware block is powered down,
the HDMI register values (incl. interrupt polarity settings) are lost.
During resume, after powering up the PM domain, interrupts are
re-enabled, and an interrupt storm happens due to incorrect interrupt
polarity settings:
irq 163: nobody cared (try booting with the "irqpoll" option)
...
Disabling IRQ #163
To fix this, re-initialize the interrupt polarity settings, and the
htop1 register block (if present), during resume.
As the .suspend_noirq() and .resume_noirq() callbacks are not called
when using the generic PM domain, the normal .resume() callback is used,
and the device interrupt needs to be disabled/enabled manually.
This fixes resume from s2ram with power down of the A4MP PM domain on
r8a7740/Armadillo.

The function bitcpy_rev has a bug that may result in screen corruption.
The bug happens under these conditions:
* the end of the destination area of a copy operation is aligned on a long
word boundary
* the end of the source area is not aligned on a long word boundary
* we are copying more than one long word
In this case, the variable shift is non-zero and the variable first is
zero. The statements FB_WRITEL(comp(d0, FB_READL(dst), first), dst) reads
the last long word of the destination and writes it back unchanged
(because first is zero). Correctly, we should write the variable d0 to the
last word of the destination in this case.
This patch fixes the bug by introducing and extra test if first is zero.
The patch also removes the references to fb_memmove in the code that is
commented out because fb_memmove was removed from framebuffer subsystem.

Commit 7edaa761ee ("video: mx3fb: Add backlight control support")
changed the mx3fb driver so it always selects the BACKLIGHT_CLASS_DEVICE
symbol, but that is hidden behind BACKLIGHT_LCD_SUPPORT in Kconfig, so
we get a Kconfig warning for multi_v5_defconfig, which doesn't have that:
Warning: (DRM_RADEON && DRM_NOUVEAU && DRM_I915 && DRM_GMA500 &&
DRM_SHMOBILE && DRM_TILCDC && FB_BACKLIGHT && FB_MX3 && USB_APPLEDISPLAY
&& FB_OLPC_DCON && ASUS_LAPTOP && SONY_LAPTOP && THINKPAD_ACPI &&
EEEPC_LAPTOP && ACPI_CMPC && SAMSUNG_Q10) selects BACKLIGHT_CLASS_DEVICE
which has unmet direct dependencies (HAS_IOMEM && BACKLIGHT_LCD_SUPPORT)
This makes sure we always enable both symbols together for mx3fb, like
we do for the other drivers that can't be built without backlight
support. Note that a better solution would be to ensure the driver can
work with or without backlight support.

When looking at this driver for a client, I noticed the code that
configures the HSYNC pulse clobbers the display width in the same
register. It only preserves the MS part of the width in bit 3 and zeros
the LS part of the width in bits 9 to 4. This doesn't matter during
initialization as the width is configured afterwards, but subsequent use
of the FBIPUT_HSYNC ioctl would clobber the width.
Preserve bits 9 to 0 of LCD_RASTER_TIMING_0_REG when configuring the
horizontal sync.

If the device-tree specifies a max-memory-bandwidth property then the
CLCD driver uses that to calculate the bits-per-pixel supported,
however, this calculation is faulty for two reasons.
1. It doesn't ensure that the result is a sane value, i.e. a power of 2
and <= 32 as the rest of the code assumes.
2. It uses the displayed resolution and calculates the average bandwidth
across the whole frame. It should instead calculate the peak
bandwidth based on the pixel clock.
This patch fixes both the above.

This merge window brings a good size of cleanups on various
platforms. Among the bigger ones:
* Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
lacked active support for quite a while, and after asking around nobody
showed interest in keeping them around. If needed, they could be
resurrected in the future but it's more likely that we would prefer
reintroduction of them as DT and multiplatform-enabled platforms
instead.
* OMAP4 controller code register define diet. They defined a lot of registers
that were never actually used, etc.
* Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
to drivers/soc so it can be shared with 64-bit code. This also converts them
over to traditional driver models where possible.
* Removal of legacy gpio-samsung driver, since the last users have been
removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some misc
cleanups, etc.

Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"This merge window brings a good size of cleanups on various platforms.
Among the bigger ones:
- Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
have lacked active support for quite a while, and after asking
around nobody showed interest in keeping them around. If needed,
they could be resurrected in the future but it's more likely that
we would prefer reintroduction of them as DT and
multiplatform-enabled platforms instead.
- OMAP4 controller code register define diet. They defined a lot of
registers that were never actually used, etc.
- Move of some of the Tegra platform code (PMC, APBIO, fuse,
powergate) to drivers/soc so it can be shared with 64-bit code.
This also converts them over to traditional driver models where
possible.
- Removal of legacy gpio-samsung driver, since the last users have
been removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some
misc cleanups, etc"

In drm/i915 we want to get at the video= cmdline modes even when we
don't have fbdev support enabled, so that users can always override
the kernel's initial mode selection.
But that gives us a direct depency upon the parsing code in the fbdev
subsystem. Since it's so little code just extract these 2 functions
and always build them in.
Whiel at it fix the checkpatch fail in this code.

We don't want random users to be able to spam the logs, and commit

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM
panic because the notification work is done in a workqueue, and in panic() the
kernel typically ends up in an infinite loop, and a typical kernel config has
CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch
can't happen in panic() and the workqueue won't have a chance to run. As a
result, the VM Connection window can't refresh until it's closed and we
re-connect to the VM.
We can register a handler on panic_notifier_list: the handler can notify
the VSC and switch the framebuffer driver to a "synchronous mode", meaning
the VSC flushes any future framebuffer change to the VSP immediately.

The Versatile CLCD helpers call dma_alloc_writecombine() which is only
available on ARM and AVR32, meaning they won't build on other platforms
including arm64. Unfortunately the current Kconfig enables the symbol
by default if ARCH_VEXPRESS is defined which means that it is enabled on
arm64 when building for the ARM reference platforms and models for ARMv8
since they have many hardware similarities with their pre-ARMv8 systems.
Since all the systems that need the helpers are ARM systems fix this by
adding a dependency on ARM.

commit 11c32d7b62 ("video: move Versatile CLCD helpers")
moved files out of the plat-versatile directory but in the process
got a few of the dependencies wrong:
- If CONFIG_FB is not set, the file no longer gets built, resulting
in a link error
- If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a
Kconfig warning for incorrect dependencies due to the symbol
being 'select'ed from the platform Kconfig.
- When the file is not built, we also get a link error for missing
symbols.
This patch should fix all three, by removing the 'select' statements,
changing the Kconfig description of the symbol to be enabled in
exactly the right configurations, and adding inline stub functions
for the case when the framebuffer driver is disabled.

Commit b4aa016305 ("efifb: Implement vga_default_device() (v2)") added
efifb vga_default_device() so EFI systems that do not load shadow VBIOS or
setup VGA get proper value for boot_vga PCI sysfs attribute on the
corresponding PCI device.
Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such
as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then
bails out with "no devices detected".
Note: When vga_default_device() is set boot_vga PCI sysfs attribute
reflects its state. When unset this attribute is 1 whenever
IORESOURCE_ROM_SHADOW flag is set.
With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete
while having native drivers for the GPU also makes selecting sysfb/efifb
optional.
Remove the efifb implementation of vga_default_device() and initialize
vgaarb's vga_default_device() with the PCI GPU that matches boot
screen_info in pci_fixup_video().

We use devm_kzalloc() to allocate memory for the struct vt8500lcd_info
pointer fbi, so there is no need to free it in vt8500lcd_remove().

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available. The function
mddi_dummy_remove is removed as it is no longer required after
removing the kfree. The variable ret is also done away with.
The following Coccinelle semantic patch was used for making a part of
the change:
@platform@
identifier p, probefn, removefn;
@@
struct platform_driver p = {
.probe = probefn,
.remove = removefn,

This adds support for the framebuffer available in the Cirrus
Logic CLPS711X CPUs.
FB features:
- 1-2-4 bits per pixel.
- Programmable panel size to a maximum of 1024x256 at 4 bps.
- Relocatible Frame Buffer (SRAM or SDRAM).
- Programmable refresh rates.
- 16 gray scale values.
This new driver is designed to usage with devicetree only.
The driver have been tested with custom board equipped
Cirrus Logic EP7312.

A list that was intended for storing power control GPIOs was never
initialized correctly or filled. Without these lines of added code
the kernel hangs when trying to access an uninitialized list when a
power control GPIO is registered with the device tree.

This reverts commit e1edf18b20.
This patch was a misguided attempt at fixing offb for LE ppc64
kernels on BE qemu but is just wrong ... it breaks real LE/LE
setups, LE with real HW, and existing mixed endian systems
that did the fight thing with the appropriate device-tree
property. Bad reviewing on my part, sorry.
The right fix is to either make qemu change its endian when
the guest changes endian (working on that) or to use the
existing foreign endian support.

re-add the perm check (we unified the module param and sysfs checks, but
the module ones were stronger so we weakened them temporarily).
Param parsing gets documented, and also "--" now forces args to be
handed to init (and ignored by the kernel).
Module NX/RO protections get tightened: we now set them before calling
parse_args().
Cheers,
Rusty.

Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.
The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

The new atari_stram_alloc interface returns kernel virtual addresses
even if the kernel runs in FastRAM. These addresses are not
guaranteed to be identical with the physical addresses. Since ST-RAM
mappings have not been set up by mem_init, virt_to_phys() and its
cousin do not work and the atari_stram_to_phys() etc. helpers must
be used to determine physical addresses.
fb.fix->smem_start needs physical addresses, fb.par->screen_base
needs virtual addresses. Take care of the virt-to-phys conversion
both on fb init and par changes.
