This reverts commit 3510e7a7f91088159bfc67e8abdc9f9e77d28870.
During the 4.19 merge window for drm-misc, two patches critical to
supporting the display pipeline on the Allwinner R40 SoC were missed.
They were applied later but missed the merge window deadline. As a
result 4.19-rc1 kernel would crash on the R40 when it couldn't parse
the new device tree structure. We ended up removing support for the
R40 display pipeline for 4.19.
Since the missing patches are already merged for 4.20, we can now
revert the commit that removed support.

The lcdif block is only powered on when display is active so plane
updates when not enabled are not valid. Writing to an unpowered IP block
is mostly ignored but can trigger bus errors on some chips.
Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm
and having the drm core ensure atomic_plane_update is only called while
the crtc is active. This avoids having to keep track of "enabled" bits
inside the mxsfb driver.
This also requires handling the vblank event for disable from
mxsfb_pipe_disable.

LCDIF will repeatedly display data from CUR_BUF and set CUR_BUF to
NEXT_BUF when done. Since we are only ever writing to NEXT_BUF the
display will show an initial corrupt frame.

The main axi clk is disabled at the end of mxsfb_crtc_mode_set_nofb and
immediately reenabled in mxsfb_enable_controller.
Avoid this by moving the handling of axi clk one level up to
mxsfb_crtc_enable. Do the same for mxsfb_crtc_disable for symmetry.
This shouldn't have any functional effect.

All Tegra DRM devices are getting attached to an implicit IOMMU DMA
domain if CONFIG_ARM_DMA_USE_IOMMU=y. Since Tegra DRM driver manages IOMMU
by itself, the devices must be detached from the implicit domain using
arch-specific IOMMU-API. Note that this works only for arm32 and not for
arm64, which will remain broken if CONFIG_IOMMU_DMA is enabled.

Tegra194 contains a fourth display controller that does not own any
windows. Therefore, we cannot currently assign a primary plane to it
which causes KMS to eventually crash. Do not register the display
controller if it owns no windows to work around this.
Note that we still have to enable and probe the display controller
because for some reason all display controllers need to be powered
(and/or clocked) before any registers can be accessed in any of the
display controllers.

Implement vmap/vunmap so we can export dmabufs to
other drivers, such as video4linux.
Tested with a virtio-gpu / vivid (virtual capture driver)
pipeline, where the vivid driver imports the dmabufs exported
by virtio-gpu.
Note that dma_buf_vmap() does its own vmap counting, so
it's not needed to take care of it in the driver.

Currently, virtio_gpu_object_kmap() is only called by
virtio_gpufb_create(), when a DRM framebuffer is created.
Thus, instead of returning the vmap'ed address, emit a warning

object. With this change, kmap/kunmap calls are now balanced.

The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.
The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.

Currently the driver overwrites the surface depth provided by the fb
helper to give an invalid bpp/surface depth combination.
This has been exposed by commit 70109354fed2 ("drm: Reject unknown legacy
bpp and depth for drm_mode_addfb ioctl"), which now causes the driver to
fail to probe.
Fix by not overwriting the surface depth.

In hibmc_drm_fb_create(), when the call to hibmc_framebuffer_init() fails
with error, do not store the error code in the HiBMC device frame-buffer

Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code
on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order
mode_config bit so drm_mode_addfb() asks for the correct format code.
Both DRM_FORMAT_* and VIRTIO_GPU_FORMAT_* are defined to be little
endian, so using a different mapping on bigendian machines is wrong.
It's there because of broken drm_mode_addfb() behavior. So with
drm_mode_addfb() being fixed we can fix this too.
While wading through the code I've noticed we have a little issue in
virtio: We attach a format to the bo when it is created
(DRM_IOCTL_MODE_CREATE_DUMB), not when we map it as framebuffer
(DRM_IOCTL_MODE_ADDFB). Easy way out: Support a single format only.
Pick DRM_FORMAT_HOST_XRGB8888, it is the only one actually used in
practice. Drop unused mappings in virtio_gpu_translate_format().
With this patch applied both ADDFB and ADDFB2 ioctls work correctly in
the virtio-gpu.ko driver on big endian machines. Without the patch only
ADDFB (which still seems to be used by the majority of userspace) works
correctly.

Add bochs_hw_set_*_endian() helper functions, to set the framebuffer
byteorder at mode set time. Support both DRM_FORMAT_XRGB8888 and
DRM_FORMAT_BGRX8888 framebuffer formats, no matter what the native
machine byte order is.

Use DRM_FORMAT_HOST_XRGB8888, so we are using the correct format code
on bigendian machines. Also set the quirk_addfb_prefer_host_byte_order
mode_config bit so drm_mode_addfb() asks for the correct format code.
Create our own plane and use drm_crtc_init_with_planes() instead of
depending on the default created by drm_crtc_init(). That way the plane
format list is correct on bigendian machines.
Also re-add the framebuffer format check dropped by "df2052cc92 bochs:
convert to drm_fb_helper_fbdev_setup/teardown".
With this patch applied both ADDFB and ADDFB2 ioctls work correctly in
the bochs-drm.ko driver on big endian machines. Without the patch only
ADDFB (which still seems to be used by the majority of userspace) works
correctly.

Creating framebuffers for fbdev emulation should use the correct format
code too, so switch drm_gem_fbdev_fb_create() over to use the new
drm_driver_legacy_fb_format() function.

Turns out we need the pixel format fixup not only for the addfb ioctl,
but also for fbdev emulation code.
Ideally we would place it in drm_mode_legacy_fb_format(). That would
create alot of churn though, and most drivers don't care because they
never ever run on a big endian platform. So add a new
drm_driver_legacy_fb_format() function instead which looks at the
mode_config->quirk_addfb_prefer_host_byte_order flag.

Pass virtio_gpu_object down to virtio_gpu_cmd_transfer_to_host_2d and
virtio_gpu_cmd_transfer_to_host_3d functions, instead of passing just
the virtio resource handle.
This is needed to lookup the scatter list of the object, for dma sync.

The CMA helper is already using the drm_fb_helper_generic_probe part of
the generic fbdev emulation. This patch makes full use of the generic
fbdev emulation by using its drm_client callbacks. This means that
drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are
now handled by the emulation code. Additionally fbdev unregister happens
automatically on drm_dev_unregister().
The drm_fbdev_generic_setup() call is put after drm_dev_register() in the
driver. This is done to highlight the fact that fbdev emulation is an
internal client that makes use of the driver, it is not part of the
driver as such. If fbdev setup fails, an error is printed, but the driver
succeeds probing.

drm_fbdev_generic_setup() handles mode_config.num_connector being zero.
In that case it retries fbdev setup on the next .output_poll_changed.
