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/msg871357.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. v3->v4: * Use 'fsl,sc-resource' DT property to get the SCU resource ID associated with the PXL2DPI instance instead of using alias ID. (Rob) * Add Rob's R-b tag on patch 11/14. v2->v3: * Drop 'fsl,syscon' DT properties from fsl,imx8qxp-ldb.yaml and fsl,imx8qxp-pxl2dpi.yaml. (Rob) * Mention the CSR module controls LDB and PXL2DPI in fsl,imx8qxp-ldb.yaml and fsl,imx8qxp-pxl2dpi.yaml. * Call syscon_node_to_regmap() to get regmaps from LDB bridge helper driver and PXL2DPI bridger driver instead of syscon_regmap_lookup_by_phandle(). * Drop two macros from pixel link bridge driver which help define functions and define them directly. * Properly disable all pixel link controls to POR value by calling imx8qxp_pixel_link_disable_all_controls() from imx8qxp_pixel_link_bridge_probe(). * Add Rob's R-b tags on patch 4/14 and 6/14. v1->v2: * Rebase the series upon the latest drm-misc-next branch(5.11-rc2 based). * Use graph schema in the dt-bindings of the bridges. (Laurent) * Require all four pixel link output ports in fsl,imx8qxp-pixel-link.yaml. (Laurent) * Side note i.MX8qm/qxp LDB official name 'pixel mapper' in fsl,imx8qxp-ldb.yaml. (Laurent) * Mention pixel link is accessed via SCU firmware in fsl,imx8qxp-pixel-link.yaml. (Rob) * Use enum instead of oneOf + const for the reg property of pixel combiner channels in fsl,imx8qxp-pixel-combiner.yaml. (Rob) * Rewrite the function to find the next bridge in pixel link bridge driver by properly using OF APIs and dropping unnecessary DT validation. (Rob) * Drop unnecessary port availability check in i.MX8qxp pixel link to DPI bridge driver. * Drop unnecessary DT validation from i.MX8qxp LDB bridge driver. * Use of_graph_get_endpoint_by_regs() and of_graph_get_remote_endpoint() to get the input remote endpoint in imx8qxp_ldb_set_di_id() of i.MX8qxp LDB bridge driver. * Avoid using companion_port OF node after putting it in imx8qxp_ldb_parse_dt_companion() of i.MX8qxp LDB bridge driver. * Drop unnecessary check for maximum available LDB channels from i.MX8qm LDB bridge driver. * Mention i.MX8qm/qxp LDB official name 'pixel mapper' in i.MX8qm/qxp LDB bridge drivers and Kconfig help messages.
