There's no need to include either linux/hdmi.h or drm/drm_mode.h. They can be removed by using forward declarations. While at it, group the forward declarations together, and remove the unnecessary ones. Signed-off-by:

This is only a cosmetic change. This replaces a hand-crafted EPROBE_DEFER handling for deciding to print an error message with dev_err_probe. A side-effect is that dev_err_probe also adds a debug message when it's not EPROBE_DEFER, but this is seen as an improvement. Cc: Quentin Schulz <foss+kernel@0leil.net> Signed-off-by:

devm_gpiod_get_optional may return EPROBE_DEFER in case the GPIO controller isn't yet probed when the panel driver is being probed. In that case, a spurious and confusing error message about not being able to get the reset GPIO is printed even though later on the device actually manages to get probed. Use dev_err_probe instead so that the message is only printed when it truly matters. Cc: Quentin Schulz <foss+kernel@0leil.net> Signed-off-by:

This scary message can misled the user into thinking something bad has happened and needs to be fixed, however it could simply be part of a normal boot process where EPROBE_DEFER is taken into account. Therefore, let's use dev_err_probe so that this message doesn't get shown (by default) when the return code is EPROBE_DEFER.

ret variable stores the return value of drm_of_find_panel_or_bridge which can return error codes different from EPROBE_DEFER. Therefore, let's just return that error code instead of forcing it to EPROBE_DEFER.

As per TRM this controller supports pixelclocks starting from 25 MHz. The maximum supported pixelclocks are defined by the phy configurations we have. Also it can't support modes that require doubled clocks. If the variant has a phy reference clock we can additionally validate against VESA DMT'srecommendations. Signed-off-by:

This variant requires the phy reference clock to be enabled before the DDC block can work and the (initial) DDC bus frequency is calculated based on the rate of this clock. Besides the only difference is phy configuration required to make the driver working for this variant as well. Signed-off-by:

Alex Bee authored
In preparation to support RK3128's integration of the controller, this patch adds a simple variant implementation. They mainly differ in the phy configuration required, so those are part of the match_data. The values have been taken from downstream. The pixelclocks in there are meant to be max-inclusive.

Switch to a new plane state requires unreferencing of all held surfaces. In the work required for mob cursors the mapped surfaces started being cached but the variable indicating whether the surface is currently mapped was not being reset. This leads to crashes as the duplicated state, incorrectly, indicates the that surface is mapped even when no surface is present. That's because after unreferencing the surface it's perfectly possible for the plane to be backed by a bo instead of a surface. Reset the surface mapped flag when unreferencing the plane state surface to fix null derefs in cleanup.
