drm/msm/dsi: Enable runtime PM

2024-02-05T20:17:11Z

commit 6ab502bc1cf3147ea1d8540d04b83a7a4cb6d1f1 upstream. Some devices power the DSI PHY/PLL through a power rail that we model as a GENPD. Enable runtime PM to make it suspendable.

drm/msm/dsi: Use pm_runtime_resume_and_get to prevent refcnt leaks

2024-01-25T23:45:00Z

[ Upstream commit 3d07a411b4faaf2b498760ccf12888f8de529de0 ] This helper has been introduced to avoid programmer errors (missing _put calls leading to dangling refcnt) when using pm_runtime_get, use it. While at it, start checking the return value.

Fixes for v6.7-rc3: - Fix the VREG_CTRL_1 for 4nm CPHY to match downstream - Remove duplicate call to drm_kms_helper_poll_init() in msm_drm_init() - Fix the safe_lut_tbl[] for sc8280xp to match downstream - Don't attach the drm_dp_set_subconnector_property() for eDP - Fix to attach drm_dp_set_subconnector_property() for DP. Otherwise there is a bootup crash on multiple targets - Remove unnecessary NULL check left behind during cleanup Signed-off-by: Dave Airlie From: Rob Clark Link: https://patchwork.freedesktop.org/patch/msgid/CAF6AEGtkna3P3mvaF53n2ARJACaXQU+OFfShayTrsUVmqCOmNQ@mail.gmail.com

drm/msm/dsi: use the correct VREG_CTRL_1 value for 4nm cphy

Use the same value as the downstream driver. This change is needed for CPHY mode to work correctly.

drm/msm/dsi: free TX buffer in unbind

2023-10-16T14:27:33Z

If the drm/msm init code gets an error during output modeset initialisation, the kernel will report an error regarding DRM memory manager not being clean during shutdown. This is because msm_dsi_modeset_init() allocates a piece of GEM memory for the TX buffer, but destruction of the buffer happens only at msm_dsi_host_destroy(), which is called during DSI driver's remove() time, much later than the DRM MM shutdown. To solve this issue, move the TX buffer destruction to dsi_unbind(), so that the buffer is destructed at the correct time. Note, we also have to store a reference to the address space, because priv->kms->aspace is cleared before components are unbound.

drm/msm/dsi: use msm_gem_kernel_put to free TX buffer

2023-10-16T14:27:33Z

Use exiting function to free the allocated GEM object instead of open-coding it. This has a bonus of internally calling msm_gem_put_vaddr() to compensate for msm_gem_get_vaddr() in msm_get_kernel_new().

Make MSM DSI driver use devm_drm_bridge_add() instead of plain drm_bridge_add(). As the driver doesn't require any additional cleanup, stop adding created bridge to the priv->bridges array.
