6f710918df drm/mediatek: Fix iommu fault during crtc enabling
[ Upstream commit 53412dc2905401207f264dc30890f6b9e41524a6 ]

The difference between drm_atomic_helper_commit_tail() and
drm_atomic_helper_commit_tail_rpm() is
drm_atomic_helper_commit_tail() will commit plane first and
then enable crtc, drm_atomic_helper_commit_tail_rpm() will
enable crtc first and then commit plane.

Before mediatek-drm enables crtc, the power and clk required
by OVL have not been turned on, so the commit plane cannot be
committed before crtc is enabled. That means OVL layer should
not be enabled before crtc is enabled.
Therefore, the atomic_commit_tail of mediatek-drm is hooked with
drm_atomic_helper_commit_tail_rpm().

Another reason is that the plane_state of drm_atomic_state is not
synchronized with the plane_state stored in mtk_crtc during crtc enablng,
so just set all planes to disabled.

d0952ce316 drm/mediatek: Fix backport issue in mtk_drm_gem_prime_vmap()
When building with clang:

  drivers/gpu/drm/mediatek/mtk_drm_gem.c:255:10: error: incompatible integer to pointer conversion returning 'int' from a function with result type 'void *' [-Wint-conversion]

        |                        ^~~~~~~
  1 error generated.

GCC reports the same issue as a warning, rather than an error.

Prior to commit 7e542ff8b463 ("drm/mediatek: Use struct dma_buf_map in
GEM vmap ops"), this function returned a pointer rather than an integer.
This function is indirectly called in drm_gem_vmap(), which treats NULL
as -ENOMEM through an error pointer. Return NULL in this block to
resolve the warning but keep the same end result.

6a89ddee16 drm/mediatek: Clean dangling pointer on bind error path
[ Upstream commit 36aa8c61af55675ed967900fbe5deb32d776f051 ]

mtk_drm_bind() can fail, in which case drm_dev_put() is called,
destroying the drm_device object. However a pointer to it was still
being held in the private object, and that pointer would be passed along
to DRM in mtk_drm_sys_prepare() if a suspend were triggered at that
point, resulting in a panic. Clean the pointer when destroying the
object in the error path to prevent this from happening.

da5fd53999 drm/mediatek: dsi: Reduce the time of dsi from LP11 to sending cmd
[ Upstream commit 91aeaed2c1147e3b1157dc084d23f190856a6c23 ]

According to Figure 16 Turnaround Procedure on page 36 in [1], you
can see the status of LP-00 -> LP10 -> LP11. This state can correspond
to the state of DSI from LP00 -> LP11 in mtk_dsi_lane_ready function
in mtk_dsi.c.

LP-00 -> LP10 -> LP11 takes about 2*TLPX time (refer to [1] page 51
to see that TLPX is 50ns)

The delay at the end of the mtk_dsi_lane_ready function should be
greater than the 2*TLPX specified by the DSI spec, and less than
the time specified by the DSI_RX (generally 6ms to 40ms), to avoid
problems caused by the RX specification

fd938b4ce0 drm/mediatek: dsi: Move mtk_dsi_stop() call back to mtk_dsi_poweroff()
[ Upstream commit 90144dd8b0d137d9e78ef34b3c418e51a49299ad ]

As the comment right before the mtk_dsi_stop() call advises,
mtk_dsi_stop() should only be called after
mtk_drm_crtc_atomic_disable(). That's because that function calls
drm_crtc_wait_one_vblank(), which requires the vblank irq to be enabled.

Previously mtk_dsi_stop(), being in mtk_dsi_poweroff() and guarded by a
refcount, would only be called at the end of
mtk_drm_crtc_atomic_disable(), through the call to mtk_crtc_ddp_hw_fini().
Commit cde7e2e35c28 ("drm/mediatek: Separate poweron/poweroff from
enable/disable and define new funcs") moved the mtk_dsi_stop() call to
mtk_output_dsi_disable(), causing it to be called before
mtk_drm_crtc_atomic_disable(), and consequently generating vblank
timeout warnings during suspend.

Move the mtk_dsi_stop() call back to mtk_dsi_poweroff() so that we have
a working vblank irq during mtk_drm_crtc_atomic_disable() and stop
getting vblank timeout warnings.

2d05cf1069 drm/mediatek: Keep dsi as LP00 before dcs cmds transfer
[ Upstream commit 39e8d062b03c3dc257d880d82bd55cdd9e185a3b ]

To comply with the panel sequence, hold the mipi signal to LP00 before
the dcs cmds transmission, and pull the mipi signal high from LP00 to
LP11 until the start of the dcs cmds transmission.

The normal panel timing is :
(1) pp1800 DC pull up
(2) avdd & avee AC pull high
(3) lcm_reset pull high -> pull low -> pull high
(4) Pull MIPI signal high (LP11) -> initial code -> send video data
    (HS mode)

The power-off sequence is reversed.
If dsi is not in cmd mode, then dsi will pull the mipi signal high in
the mtk_output_dsi_enable function. The delay in lane_ready func is
the reaction time of dsi_rx after pulling up the mipi signal.
