This patch series updates the Armada DRM driver to be more DT friendly by converting it to the component helper. This is an incomplete conversion as we also need to convert the TDA998x as well, hence it currently retains the existing method of initialisation using the slave encoder mechanism. The old mechanism will be removed once the conversion is complete.
This series includes the component updates (patches 1-3 which have been recently merged into Greg's driver tree, patch 9 which is scheduled to be merged) and the recently posted DRM OF helper for encoders (patch 8). Hence patches 1-3 and 9 are only included for reference purposes. Please direct comments for patch 8 to the previously posted RFC for that single patch.
The general idea here is to permit each CRTC device to exist as a separate device node in DT (as it should be) with all the appropriate properties such as base address, interrupt and pixel clocks.
The encoders (which may be off-SoC) will be specified separately in DT, and the connectivity specified via the DT's graph bindings.
The diffstat below is for the entire series, which includes the component helpre updates and the DRM OF helper.
