Dave Airlie e411295e3e imx-drm probing fix
Commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading")
 broke probing of the imx-drm driver in the non-modular case because the
 unset dev->of_node during probing of imx-ipuv3-crtc would cause the
 component matching to fail. This patch patch instead matches against
 an of_node pointer stored in platform data, allowing dev->of_node to
 be left unset for the platform probed imx-ipuv3-crtc devices.

Philipp Zabel 310944d148 drm/imx: Match imx-ipuv3-crtc components using device node in platform data
The component master driver imx-drm-core matches component devices using
their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc
module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during
probing. Before that, of_node was set and caused an of: modalias to be
used instead of the platform: modalias, which broke module autoloading.

On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc
probe function calls component_add, component matching in imx-drm-core
fails. While dev->of_node will be set once the next component tries to
bring up the component master, imx-drm-core component binding will never
succeed if one of the crtc devices is probed last.

Add of_node to the component platform data and match against the
pdata->of_node instead of dev->of_node in imx-drm-core to work around
this problem.

omapdrm and omapfb still share the same include/video/omapdss.h. We need
to change that so that we can proceed with omapdrm work.

However, it's not trivial to make separate omapfb and omapdrm versions
of omapdss.h, as that file is also included in other places like arch
code, audio code and omap_vout code. So we'll do it piece by piece.

This patch makes private versions of all the dispc function declarations
that are in omapdss.h. For omapdrm we create a new file,
drivers/gpu/drm/omapdrm/dss/omapdss.h, which will contain headers meant
to be visible outside omapdss.

We are about to make a private copy of omapdss for omapfb and for

use of these config symbols in omapdss.h which needs to be removed.

Luckily we can just delete the use of CONFIG_OMAP2_DSS_VENC from
omapdss, as it's used only to hide extern declarations, and there's no
harm to have those declarations even if CONFIG_OMAP2_DSS_VENC is not

Geert Uytterhoeven 34280340b1 fbdev: Remove unused SH-Mobile HDMI driver
As of commit 44d88c754e ("ARM: shmobile: Remove legacy SoC code
for R-Mobile A1"), the SH-Mobile HDMI driver is no longer used.
In theory it could still be used on R-Mobile A1 SoCs, but that requires
adding DT support to the driver, which is not planned.

Remove the driver, it can be resurrected from git history when needed.

Linus Torvalds 12f03ee606 libnvdimm for 4.3:
1/ Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
    mechanism for adding device-driver-discovered memory regions to the
    kernel's direct map.  This facility is used by the pmem driver to
    enable pfn_to_page() operations on the page frames returned by DAX
    ('direct_access' in 'struct block_device_operations'). For now, the
    'memmap' allocation for these "device" pages comes from "System
    RAM".  Support for allocating the memmap from device memory will
    arrive in a later kernel.
 
 2/ Introduce memremap() to replace usages of ioremap_cache() and
    ioremap_wt().  memremap() drops the __iomem annotation for these
    mappings to memory that do not have i/o side effects.  The
    replacement of ioremap_cache() with memremap() is limited to the
    pmem driver to ease merging the api change in v4.3.  Completion of
    the conversion is targeted for v4.4.
 
 3/ Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
    driver, update the VFS DAX implementation and PMEM api to provide
    persistence guarantees for kernel operations on a DAX mapping.
 
 4/ Convert the ACPI NFIT 'BLK' driver to map the block apertures as
    cacheable to improve performance.
 
 5/ Miscellaneous updates and fixes to libnvdimm including support
    for issuing "address range scrub" commands, clarifying the optimal
    'sector size' of pmem devices, a clarification of the usage of the
    ACPI '_STA' (status) property for DIMM devices, and other minor
    fixes.

Luis R. Rodriguez 9e517ac88b drivers/video/fbdev/kyrofb: Use arch_phys_wc_add() and pci_ioremap_wc_bar()
Convert the driver from using the x86-specific MTRR code to the
architecture-agnostic arch_phys_wc_add(). It will avoid MTRR if
write-combining is available, in order to take advantage of that
also ensure the ioremapped area is requested as write-combining.

There are a few motivations for this:

a) Take advantage of PAT when available

b) Help bury MTRR code away, MTRR is architecture-specific and on
   x86 it is being replaced by PAT.

c) Help with the goal of eventually using _PAGE_CACHE_UC over
   _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
   de33c442e titled "x86 PAT: fix performance drop for glx,
   use UC minus for ioremap(), ioremap_nocache() and
   pci_mmap_page_range()")

The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the ifdeffery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get an
MTRR.

Luis R. Rodriguez f2081b81c5 video: fbdev: neofb: use arch_phys_wc_add() and ioremap_wc()
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.

There are a few motivations for this:

a) Take advantage of PAT when available

b) Help bury MTRR code away, MTRR is architecture specific and on
   x86 its replaced by PAT

c) Help with the goal of eventually using _PAGE_CACHE_UC over
   _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
   de33c442e titled "x86 PAT: fix performance drop for glx,
   use UC minus for ioremap(), ioremap_nocache() and
   pci_mmap_page_range()")

The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

Krzysztof Kozlowski 1c363c7ccc drm/exynos: Enable DP clock to fix display on Exynos5250 and other
After adding display power domain for Exynos5250 in commit
2d2c9a8d0a ("ARM: dts: add display power domain for exynos5250") the
display on Chromebook Snow and others stopped working after boot.

The reason for this suggested Andrzej Hajda: the DP clock was disabled.
This clock is required by Display Port and is enabled by bootloader.
However when FIMD driver probing was deferred, the display power domain
was turned off. This effectively reset the value of DP clock enable
register.

When exynos-dp is later probed, the clock is not enabled and display is
not properly configured:

exynos-dp 145b0000.dp-controller: Timeout of video streamclk ok
exynos-dp 145b0000.dp-controller: unable to config video

Tomi Valkeinen 7ad582be12 OMAPDSS: change signal_level & signal_edge enum values
At the moment the enum values for ACTIVE_HIGH and RISING_EDGE are 0, and
ACTIVE_LOW and FALLING_EDGE are 1, to match the values programmed to HW.
The previous patch removed this dependency.

Swap the enum values the other way around. This doesn't change the
behavior in any way, but makes it easier to debug as value of '1' means
HIGH or RISING.

Tomi Valkeinen 7a16360d56 OMAPDSS: DISPC: remove OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES
DISPC can drive data lines either on rising or falling pixel clock edge,
which can be configured by the user.

Sync lines can also be driven on rising or falling pixel clock edge, but
additionally the HW can be configured to drive the sync lines on
opposite clock edge from the data lines.

This opposite edge setting does not make any sense, as the same effect
can be achieved by just setting the sync lines to be driven on the other
edge compared to the data lines. It feels like some kind of backward
compatibility option, even if all DSS versions seem to have the same
implementation.

To simplify the code and configuration of the signals, and to make the
dispc timings more compatible with what is used on other platforms,
let's just remove the whole opposite-edge support.

The drivers that used OMAPDSS_DRIVE_SIG_OPPOSITE_EDGES setting are
changed so that they use the opposite setting from the data edge.

Tomi Valkeinen a38bb793ea OMAPDSS: fix regression with display sysfs files
omapdss's sysfs directories for displays used to have 'name' file,
giving the name for the display. This file was later renamed to
'display_name' to avoid conflicts with i2c sysfs 'name' file. Looks like
at least xserver-xorg-video-omap3 requires the 'name' file to be
present.

To fix the regression, this patch creates new kobjects for each display,
allowing us to create sysfs directories for the displays. This way we
have the whole directory for omapdss, and there will be no sysfs file
clashes with the underlying display device's sysfs files.

We can thus add the 'name' sysfs file back.

Ajay Kumar 96976c3d9a drm/exynos: Add DECON driver
This patch is based on exynos-drm-next branch of Inki Dae's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git

DECON(Display and Enhancement Controller) is the new IP
in exynos7 SOC for generating video signals using pixel data.

DECON driver can be used to drive 2 different interfaces on Exynos7:
DECON-INT(video controller) and DECON-EXT(Mixer for HDMI)

The existing FIMD driver code was used as a template to create
DECON driver. Only DECON-INT is supported as of now, and
DECON-EXT support will be added later.

The current version of the driver supports video mode displays.

Changelog v2:
- Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.

Archit Taneja ef691ff48b OMAPDSS: DT: Get source endpoint by matching reg-id
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.

Tomi Valkeinen 422b67e0b3 videomode: provide dummy inline functions for !CONFIG_OF
If CONFIG_OF is disabled but we build any driver that tries to
use of_get_display_timing, we get this link error:

ERROR: "of_get_display_timing" [drivers/gpu/drm/rcar-du/rcar-du-drm.ko] undefined!

This adds an empty inline function as an alternative, to avoid changing
each driver using this function when we want to build them without
CONFIG_OF.

Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
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.

Philipp Zabel 3f5a8a946d gpu: ipu-v3: Add CSI and SMFC module enable wrappers
IPU_CONF_..._EN bits are implementation details, not to be made public.
Add wrappers around ipu_module_enable/disable, so the CSI V4L2 driver
can enable/disable the CSI and SMFC modules.

Philipp Zabel e90460970f gpu: ipu-v3: Add ipu_idmac_get_current_buffer function
This function returns the currently active buffer (0 or 1)
of a double buffered IDMAC channel. It is to be used by the
CSI driver.

Philipp Zabel 39b9004d1f gpu: ipu-v3: Move i.MX IPUv3 core driver out of staging
The i.MX Image Processing Unit (IPU) contains a number of image processing
blocks that sit right in the middle between DRM and V4L2. Some of the modules,
such as Display Controller, Processor, and Interface (DC, DP, DI) or CMOS
Sensor Interface (CSI) and their FIFOs could be assigned to either framework,
but others, such as the dma controller (IDMAC) and image converter (IC) can
be used by both.
The IPUv3 core driver provides an internal API to access the modules, to be
used by both DRM and V4L2 IPUv3 drivers.

Tomi Valkeinen 80823ca1ba OMAPDSS: remove unused macros
Macros to_dss_driver() and to_dss_device() are no longer used, and the
latter doesn't even work. Remove them.

Arnd Bergmann 24f13a6679 video: omap2dss: fix LPAE warnings
If LPAE is enabled, dma_addr_t is 64 bit, so we have to
change a few type for everything in this driver to match
again.
