omapdrm: dss: mark runtime PM functions __maybe_unused

drm/omap: Add ovl checking funcs to dispc_ops

2021-12-08T08:04:38Z

In order to be able to dynamically assign overlays to planes we need to be able to asses the overlay capabilities. Add a helper function to be able to retrieve the supported capabilities of an overlay. And export the function to check if a fourcc is supported on a given overlay.

drm/omap: Add ability to check if requested plane modes can be supported

2021-12-08T08:04:37Z

We currently assume that an overlay has the same maximum width and maximum height as the overlay manager. This assumption is incorrect. On some variants the overlay manager maximum width is twice the maximum width that the overlay can handle. We need to add the appropriate data per variant as well as export a helper function to retrieve the data so check can be made dynamically in omap_plane_atomic_check().

drm/omap: increase DSS5 max tv pclk to 192MHz

2021-11-10T11:51:26Z

DSS5's maximum tv pclk rate (i.e. HDMI) is set to 186MHz, which comes from the TRM (DPLL_HDMI_CLK1 frequency must be lower than 186 MHz). To support DRA76's wide screen HDMI feature, we need to increase this maximum rate. Testing shows that the PLL seems to work fine even with ~240MHz clocks, and even the HDMI output at that clock is stable enough for monitors to show a picture. This holds true for all DRA7 and AM5 SoCs (and probably also for OMAP5). However, the highest we can go without big refactoring to the clocking code is 192MHz, as that is the DSS func clock we get from the PRCM. So, increase the max HDMI pixel clock to 192MHz for now, to allow some more 2k+ modes to work. This patch never had a clear confirmation from HW people, but this change stayed on production trees for multiple years without any report on an eventual breakage.

2021-11-10T11:51:25Z

Use the helper macro SET_RUNTIME_PM_OPS() instead of the verbose operators ".runtime_suspend/.runtime_resume", because the SET_RUNTIME_PM_OPS() is a nice helper macro that could be brought in to make code a little clearer, a little more concise.
