Adding lcdif nodes to a power domain currently doesn't work, it results in black/corrupted screens or hangs. While the driver does enable runtime pm it does not deal correctly with the block being unpowered. --- All patches in this series have review tags from a while ago and I tested them again on top of next-20180913. No changes since last version: https://lkml.org/lkml/2018/8/27/299 This series stalled so I reached out to Marek on IRC and he was surprised to be listed as maintainer and asked me to resend and add Daniel Vetter. Perhaps it would help to clarify that the pengutronix people should feel free to push patches in this area? Right now drm/imx is mostly for IPUv3 but there are other display output paths on imx, such as the LCDIF supported by this driver. This LCDIF block is included on imx8 so still quite relevant.
