drm/rockchip: vop2: Do not divide height twice for YUV

2024-05-30T07:49:41+00:00

[ Upstream commit e80c219f52861e756181d7f88b0d341116daac2b ]

For the cbcr format, gt2 and gt4 are computed again after src_h has been
divided by vsub.

As src_h as already been divided by 2 before, introduce cbcr_src_h and
cbcr_src_w to keep a copy of those values to be used for cbcr gt2 and
gt4 computation.

This fixes yuv planes being unaligned vertically when down scaling to
1080 pixels from 2160.

drm/rockchip: vop2: Remove AR30 and AB30 format support

[ Upstream commit 905f7d53a1bc105b22d9ffd03dc11b6b42ec6ba6 ]

The Alpha blending for 30 bit RGB/BGR are not
functioning properly for rk3568/rk3588, so remove
it from the format list.

drm/rockchip: lvds: do not print scary message when probing defer

2024-03-26T22:16:59+00:00

[ Upstream commit 52d11c863ac92e36a0365249f7f6d27ac48c78bc ]

This scary message can misled the user into thinking something bad has
happened and needs to be fixed, however it could simply be part of a
normal boot process where EPROBE_DEFER is taken into account. Therefore,
let's use dev_err_probe so that this message doesn't get shown (by
default) when the return code is EPROBE_DEFER.

drm/rockchip: lvds: do not overwrite error code

[ Upstream commit 79b09453c4e369ca81cfb670d0136d089e3b92f0 ]

ret variable stores the return value of drm_of_find_panel_or_bridge
which can return error codes different from EPROBE_DEFER. Therefore,
let's just return that error code instead of forcing it to EPROBE_DEFER.

drm/rockchip: inno_hdmi: Fix video timing

2024-03-26T22:16:59+00:00

[ Upstream commit 47a145c03484d33e65d773169d5ca1b9fe2a492e ]

The controller wants the difference between *total and *sync_start in the
HDMI_VIDEO_EXT_*DELAY registers. Otherwise the signal is very unstable for
certain non-VIC modes. See downstream commit [0].

Merge tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

2024-01-19T01:29:01+00:00

Pull i2c updates from Wolfram Sang:
 "This removes the currently unused CLASS_DDC support (controllers set
  the flag, but there is no client to use it).

  Also, CLASS_SPD support gets simplified to prepare removal in the
  future. Class based instantiation is not recommended these days
  anyhow.

  Furthermore, I2C core now creates a debugfs directory per I2C adapter.
  Current bus driver users were converted to use it.

  Finally, quite some driver updates. Standing out are patches for the
  wmt-driver which is refactored to support more variants.

  This is the rebased pull request where a large series for the
  designware driver was dropped"

drm: remove I2C_CLASS_DDC support

2024-01-18T20:10:41+00:00

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

drm/rockchip: vop2: Drop unused if_dclk_rate variable

2024-01-05T20:34:24+00:00

Commit 5a028e8f062f ("drm/rockchip: vop2: Add support for rk3588")
introduced a variable which ended up being unused:

rockchip_drm_vop2.c:1688:23: warning: variable ‘if_dclk_rate’ set but not used [-Wunused-but-set-variable]

This has been initially used as part of a formula to compute the clock
dividers, but eventually it has been replaced by static values.

Drop the variable declaration and move its assignment to the comment
block, to serve as documentation of how the constants have been
generated.
