[PATCH v7 05/13] drm: mediatek: Omit warning on probe defers

From: Matthias Brugger It can happen that the mmsys clock drivers aren't probed before the platform driver gets invoked. The platform driver used to print a warning that the driver failed to get the clocks. Omit this error on the defered probe path. Signed-off-by: Matthias Brugger Reviewed-by:

[PATCH v7 13/13] drm/mediatek: Add support for mmsys through a pdev

From: Matthias Brugger The MMSYS subsystem includes clocks and drm components. This patch adds an initailization path through a platform device for the clock part, so that both drivers get probed from the same device tree compatible. Signed-off-by: Matthias Brugger Reviewed-by: Enric Balletbo

[PATCH v7 02/13] dt-bindings: display: mediatek: Add mmsys binding description

From: Matthias Brugger The MediaTek DRM has a block called mmsys, which sets the routing and enables the different blocks. This patch adds one line for the mmsys bindings description and changes the mmsys description to use the generic form of referring to a specific Soc. Signed-off-by:

[PATCH v7 00/13] arm/arm64: mediatek: Fix mmsys device probing

From: Matthias Brugger This is version seven of the series. The biggest change is, that I added a first patch that actually moves the mmsys binding from arm/mediatek to display/mediatek, as in effect the mmsys is part of the display subsystem. Since version five, the clock probing is

[PATCH v7 01/13] dt-bindings: arm: move mmsys description to display

From: Matthias Brugger The mmsys block provides registers and clocks for the display subsystem. The binding description should therefore live together with the rest of the display descriptions. Move it to display/mediatek. Signed-off-by: Matthias Brugger --- Changes in v7: - move the binding

[PATCH] drm/mediatek: Delete not used of_device_get_match_data

From: Matthias Brugger The driver will be loaded by via a platform device. So we will need to get the device_node from the parent device. Depending on this we will set the driver data. As all this is done later already, just delete the call to of_device_get_match_data. Signed-off-by: Matthias
