drm/msm/dsi: add mode valid callback for dsi_mgr

2022-04-25T21:56:22Z

Add a mode valid callback for dsi_mgr for checking mode being valid in case of DSC. For DSC the height and width needs to be multiple of slice, so we check that here Reviewed-by: Dmitry Baryshkov Reviewed-by: Abhinav Kumar Signed-off-by: Vinod Koul Patchwork: https://patchwork.freedesktop.org/patch/480930/ Link: https://lore.kernel.org/r/20220406094031.1027376-13-vkoul@kernel.org Signed-off-by: Dmitry Baryshkov

drm/msm/dsi: Pass DSC params to drm_panel

2022-04-25T21:50:47Z

When DSC is enabled, we need to get the DSC parameters from the panel driver, so add a dsc parameter in panel to fetch and pass DSC configuration for DSI panels to DPU encoder, which will enable and then configure DSC hardware blocks accordingly.

drm/msm/dsi: fix initialization in the bonded DSI case

2021-12-08T17:12:58Z

Commit 739b4e7756d3 ("drm/msm/dsi: Fix an error code in msm_dsi_modeset_init()") changed msm_dsi_modeset_init() to return an error code in case msm_dsi_manager_validate_current_config() returns false. However this is not an error case, but a slave DSI of the bonded DSI link. In this case msm_dsi_modeset_init() should return 0, but just skip connector and bridge initialization. To reduce possible confusion, drop the msm_dsi_manager_validate_current_config() function, and specif 'bonded && !master' condition directly in the msm_dsi_modeset_init().

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.

drm/msm/dsi: do not enable irq handler before powering up the host

2021-10-15T20:26:34Z

The DSI host might be left in some state by the bootloader. If this state generates an IRQ, it might hang the system by holding the interrupt line before the driver sets up the DSI host to the known state. Move the request_irq into msm_dsi_host_init and pass IRQF_NO_AUTOEN to it. Call enable/disable_irq after msm_dsi_host_power_on/_off() functions, so that we can be sure that the interrupt is delivered when the host is in the known state. It is not possible to defer the interrupt enablement to a later point, because drm_panel_prepare might need to communicate with the panel over the DSI link and that requires working interrupt.
