Marek Vasut 6a15075ece ARM: video: mxs: Fix mxsfb misconfiguring VDCTRL0
The issue fixed by this patch manifests only then using X11
with mxsfb driver. The X11 will display either shifted image
or otherwise distorted image on the LCD.

The problem is that the X11 tries to reconfigure the framebuffer
and along the way calls fb_ops.fb_set_par() with X11's desired
configuration values. The field of particular interest is
fb_info->var.sync which contains non-standard values if
configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,
FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform
configuration. Both of these values are defined in the
include/linux/mxsfb.h file.

The driver interprets these values and configures the LCD controller
accordingly. Yet X11 only has access to the standard values for this
field defined in include/uapi/linux/fb.h and thus, unlike kernel,
omits these special values. This results in distorted image on the
LCD.

This patch moves these non-standard values into new field of the
mxsfb_platform_data structure so the driver can in turn check this
field instead of the video mode field for these specific portions.

Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix
instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

Maxime Ripard 4a38a8502b ARM: mxs: cfa10049: Fix fb initialisation function
Commit 1fe42740 ("ARM: dts: mxs: Add the LCD to the 10049 board") seem
to have been applied with some fuzzyness, and the framebuffer
initialisation code for the CFA-10049 ended up in the CFA-10037
initialisation function.

 * nomadik bindings for all devices, removing the board files
 * bcm2835 bindings for mmc and i2c
 * tegra bindings for hdmi, keyboard, audio, as well as some updates

v2 has 32bits resolution, so we have quite some headroom, and
can use the 24MHz clock.
v1 has only 16bits, so we only increase v2.

So we just exchange the timrot clock in imx28.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Setup scheduler clock on ARM MXS platforms with a 32-bit timrot
such as i.MX28. This allows the scheduler to use sub-jiffy resolution.

The corresponding change for 16-bit v1 timrots is not possible
at the moment due to rounding issues with clock values wrapping
faster than once per several seconds in the common ARM platform code.

Marek Vasut 16d477018b ARM: mx28: Skip OCOTP FEC MAC setup if in DT
Currently, the kernel unconditionally adds "local-mac-address" and
"mac-address" properties under both FEC ethernet DT nodes in case
the update_fec_mac_prop() function is called. These properties are
loaded with MAC address compiled from vendors OUI and a per-device
NIC saved in OCOTP storage.

Some more advanced bootloaders do augment the DT passed to the kernel
by these properties already. In such case, it is wrong for kernel to
override these values.

Adjust the FEC MAC address loading so that in case the DT properties
are already present in the DT passed from the bootloader, skip the
loading from OCOTP altogether. If the DT properties are not present,
load them from OCOTP.

Note that the later case will lead to zeroed out MAC address if OCOTP
is not programmed. This will lead to FEC not working at all.

Linus Torvalds 9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it
if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX
or have lots of implicit includes pulled in by mach/gpio.h.

CONFIG_NEED_MACH_GPIO_H once that is in.

Remove irq_domain_add_legacy call from mach-mxs.c and have the gpio
driver adopt irqdomain support, so that we can have the mapping
between gpio and irq number available without using virtual_irq_start
and MXS_GPIO_IRQ_START.

Marek Vasut 91ed4938ce ARM: mxs: Update DENX M28 machine and dts file
Update the mach-mxs machine by removing the enet_clkout(). The new
revision of the board doesn't need that. Also, update the DTS file
with all the new drivers pulled in the mainline recently, that is,
SPI, LRADC, USB.

Shawn Guo 44ffb78fe0 ARM: mxs: use auxdata to pass flexcan_switch function hook
There are some efforts going on to have flexcan_switch function
implemented in flexcan driver, so that this platform function hook
can be saved for device tree boot.  But due to the mx28evk board
design oddness that two flexcan transceivers share one switch gpio,
we have to come up a separate and generic gpio-switch driver to handle
all these gpio switch use cases.

Before that happens, we choose to use auxdata to pass flexcan_switch
function hook, so that the DT conversion is not blocked there.

Shawn Guo 2c7c2c1d01 ARM: mxs: tx28: reset fec phy for device tree boot
For non-DT boot, function tx28_add_fec0 configures all ENET0 pins
into gpio mode for resetting fec phy, and then reconfigures those pins
into ENET function after that.

For DT boot, all the pin configuration is done by pinctrl subsystem.
Ideally, when gpio_request gets called, GPIO subsystem should call
pinctrl to configure pins into gpio mode automatically, and have pins
freed up from pinctrl subsystem when gpio_free is called.  But right
now, this cooperation between gpio and pinctrl hasn't been available.
As the result, we have to explicitly call pinctrl_get_select and
pinctrl_put for device tree boot.

There is no need for adding board related entries into dt_board_compat.

Leave only the SoC entry.

This way we do not need to patch a C file when adding dt support for
a new board.
