fcd70cd36b drm: Split out drm_probe_helper.h
Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

af74138160 drm/tinydrm: Use damage helper for dirtyfb
This switches to drm_atomic_helper_dirtyfb() as the framebuffer dirty
handler. All flushing will now happen in the pipe functions.

Also enable the damage plane property for all except repaper which can
only do full updates.

ili9225:
This change made ili9225_init() equal to mipi_dbi_init() so use it.

v3: Include vblank header (Sam)
    ili9225 and st7586 can't use mipi_dbi_enable_flush() (David)

v2: Remove fb check in mipi_dbi_enable_flush() it can't be NULL

b051b3459b drm/tinydrm: Use struct drm_rect
This prepares for the switch to drm_atomic_helper_dirtyfb() in the next
patch. The damage helper returns a drm_rect so switch to that everywhere
including using a pointer in the dirty functions.

This is a non-functional change except for the debug print which looks a
bit different.

84056e9b45 drm/tinydrm: do not reply on drmP.h from drm_gem_cma_helper.h
drmP.h was the only header file in the past and a lot
of files rely on that drmP.h defines everything.
The goal is to one day to delete drmP.h and
as a step towards this it will no longer be included in the
headers files in include/drm/

To prepare tinydrm/ for this add dependencies that
othwewise was pulled in by drmP.h from drm_gem_cma_helper.h

To avoid that tinydrm.h became "include everything",
push include files to the individual drivers.

f300c86e33 drm: Add an hx8367d tinydrm driver.
I want to sort out support for tinydrm in vc4, so I needed to get a
tinydrm-appropriate panel working and this is what I had on hand.
This is derived from a combination of ili9341.c from tinydrm and
fb_hx8357d.c from staging's fbtft.

v2: Write my own register defs from the spec to not need the header
    from fbtft.  Fix spi device string to enable module autoloading.

This adds a new driver for display panels that use the Ilitek ILI9341
controller. It currently supports a single display panel, namely
the YX240QV29-T (e.g. Adafruit 2.4" TFT).

The init sequence is from the Adafruit Python library for the ILI9341
controller. https://github.com/adafruit/Adafruit_Python_ILI9341

6da2ec5605 treewide: kmalloc() -> kmalloc_array()
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

with:

        kmalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kmalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

The Coccinelle script used for this was:

9f99963a43 drm/tinydrm/mi0283qt: Always set rotation value
The PiTFT (ili9340) has a hardware reset circuit that resets only
on power-on and not on each reboot through a gpio like the
rpi-display does. As a result, we need to always apply the
rotation value regardless of the display "on/off" state.
Moved the rotation setting code below out_enable:.

e85d30060e drm/tinydrm: Make fb_dirty into a lower level hook
mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.

Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.

v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

7628166d5e tinydrm: add backlight dependency
Calling devm_of_find_backlight directly means we get a link failure
without CONFIG_BACKLIGHT_CLASS_DEVICE:

drivers/gpu/drm/tinydrm/mi0283qt.o: In function `mi0283qt_probe':
mi0283qt.c:(.text+0x684): undefined reference to `devm_of_find_backlight'

This adds an explicit Kconfig dependency for it. While I did not
observe that failure for st7735r, I assume the same change is needed
there for the same reason.

While at it, also ocd and give them a consistent drm_dev_ prefix, like

the right places.

8941a7cbcc drm/tinydrm: Generalize tinydrm_xrgb8888_to_gray8()
This adds parameters for vaddr and clip to tinydrm_xrgb8888_to_gray8() to
make it more generic.

dma_buf_{begin,end}_cpu_access() are moved out to the repaper driver.

Return type is change to void to simplify error handling by callers.

7d902c05b4 drm: Nuke drm_atomic_helper_connector_dpms
It's dead code, the core handles all this directly now.

The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

v2: Rebase over the panel/brideg refactorings in stm/ltdc.
