Hi, This series adds some DRM bridge drivers support for i.MX8qm/qxp SoCs. The bridges may chain one by one to form display pipes to support LVDS displays. The relevant display controller is DPU embedded in i.MX8qm/qxp SoCs. The DPU KMS driver can be found at: https://www.spinics.net/lists/arm-kernel/msg862106.html This series supports the following display pipes: 1) i.MX8qxp: prefetch eng -> DPU -> pixel combiner -> pixel link -> pixel link to DPI(PXL2DPI) -> LVDS display bridge(LDB) 2) i.MX8qm: prefetch eng -> DPU -> pixel combiner -> pixel link -> LVDS display bridge(LDB) Patch 1/14 adds LVDS PHY configuration options, which has already been sent with the following series to add Mixel combo PHY found in i.MX8qxp: https://www.spinics.net/lists/arm-kernel/msg862560.html Patch 2/14 and 3/14 add bus formats used by PXL2DPI. Patch 4/14 ~ 13/14 add drm bridge drivers and dt-bindings support for the bridges. Patch 14/14 updates MAINTAINERS. I've tested this series with a koe,tx26d202vm0bwa dual link LVDS panel and a LVDS to HDMI bridge(with a downstream drm bridge driver). Welcome comments, thanks.
