drm/msm/hdmi: Add missing check for alloc_ordered_workqueue

2023-03-10T08:33:10Z

[ Upstream commit afe4cb96153a0d8003e4e4ebd91b5c543e10df84 ] Add check for the return value of alloc_ordered_workqueue as it may return NULL pointer and cause NULL pointer dereference in `hdmi_hdcp.c` and `hdmi_hpd.c`.

drm/msm/hdmi: use devres helper for runtime PM management

[ Upstream commit b964444b2b64ce182495731d830499d1c588ccf6 ] Use devm_pm_runtime_enable() to enable runtime PM. This way its effect will be reverted on device unbind/destruction.

drm/msm/hdmi: fix IRQ lifetime

2022-09-30T16:57:53Z

Device-managed resources allocated post component bind must be tied to the lifetime of the aggregate DRM device or they will not necessarily be released when binding of the aggregate device is deferred. This is specifically true for the HDMI IRQ, which will otherwise remain requested so that the next bind attempt fails when requesting the IRQ a second time. Fix this by tying the device-managed lifetime of the HDMI IRQ to the DRM device so that it is released when bind fails.

drm/msm/hdmi: fix memory corruption with too many bridges

drm/msm/hdmi: make hdmi_phy_8996 OF clk provider

2022-09-18T16:38:07Z

On MSM8996 the HDMI PHY provides the PLL clock to the MMCC. As we are preparing to convert the MSM8996 to use DT clocks properties (rather than global clock names), register the OF clock provider. While we are at it, also change the driver to use clk_parent_data rather parent_names to setup a link to the XO clock.
