msm-fixes for v6.3-rc4 Display Fixes: - Fix the documentation for dpu_encoder_phys_wb_init() and dpu_encoder_phys_wb_setup_fb() APIs to address doc warnings - Remove vcca-supply and vdds-supply as mandatory for 14nm PHY and 10nm PHY DT schemas respectively as they are not present on some SOCs using these PHYs - Add the dsi-phy-regulator-ldo-mode to dsi-phy-28nm.yaml as it was missed out during txt to yaml migration - Remove operating-points-v2 and power-domain as a required property for the DSI controller as thats not the case for every SOC - Fix the description from display escape clock to display core clock in the dsi controller yaml - Fix the memory leak for mdp1-mem path for the cases when we return early after failing to get mdp0-mem ICC paths for msm - Fix error handling path in msm_hdmi_dev_probe() to release the phy ref count when devm_pm_runtime_enable() fails - Fix the dp_aux_isr() routine to make sure it doesnt incorrectly signal the aux transaction as complete if the ISR was not an AUX isr. This fixes a big hitter stability bug on chromebooks. - Add protection against null pointer dereference when there is no kms object as in the case of headless adreno GPU in the shutdown path. GPU Fixes: - a5xx: fix quirks to actually be a bitmask and not overwrite each other - a6xx: fix gx halt sequence to avoid 1000ms hang on some devices - kexec shutdown fix - fix potential double free Signed-off-by: Dave Airlie From: Rob Clark Link: https://patchwork.freedesktop.org/patch/msgid/CAF6AEGv7=in_MHW3kdkhqh7ZFoVCmnikmr29YYHCXR=7aOEneg@mail.gmail.com

drm/msm/mdp5: fix reading hw revision on db410c platform

2022-11-26T10:05:37+00:00

Since the commit commit c6122688f265 ("drm/msm/mdp5: stop overriding drvdata") reading the MDP5 hw revision on db410c will crash the board as the MDSS_GDSC is not enabled. Revert a part of the offending commit (moving rpm enablement) and set priv->kms earlier. This make it possible to use pm_runtime_get_sync() during read_mdp_hw_revision(), which will power up both the MDP5 and MDSS devices.

drm/msm/dpu1: Account for DSC's bits_per_pixel having 4 fractional bits

2022-11-04T14:39:41+00:00

According to the comment this DPU register contains the bits per pixel as a 6.4 fractional value, conveniently matching the contents of bits_per_pixel in struct drm_dsc_config which also uses 4 fractional bits. However, the downstream source this implementation was copy-pasted from has its bpp field stored _without_ fractional part. This makes the entire convoluted math obsolete as it is impossible to pull those 4 fractional bits out of thin air, by somehow trying to reuse the lowest 2 bits of a non-fractional bpp (lsb = bpp % 4??). The rest of the code merely attempts to keep the integer part a multiple of 4, which is rendered useless thanks to data |= dsc->bits_per_pixel << 12; already filling up those bits anyway (but not on downstream).
