drm/msm/dsi: Add dsi phy tuning configuration support

2022-02-18T15:32:59Z

Add support for MSM DSI PHY tuning configuration. Current design is to support drive strength and drive level/amplitude tuning for 10nm PHY version, but this can be extended to other PHY versions.

drm/msm/dsi: invalid parameter check in msm_dsi_phy_enable

2022-01-25T02:48:13Z

The function performs a check on the "phy" input parameter, however, it is used before the check. Initialize the "dev" variable after the sanity check to avoid a possible NULL pointer dereference.

drm/msm: Don't use autosuspend for display

2021-12-16T17:51:25Z

No functional change, as we only actually enable autosuspend for the GPU device. But lets not encourage thinking that autosuspend is a good idea for anything display related.

drm/msm/dsi: stop setting clock parents manually

2021-11-28T17:32:03Z

There is no reason to set clock parents manually, use device tree to assign DSI/display clock parents to DSI PHY clocks. Dropping this manual setup allows us to drop repeating code and to move registration of hw clock providers to generic place.
