2023-06-05drm/bridge: imx: turn imx8{qm,qxp}-ldb into single-object modulesMasahiro Yamada
With the previous fix, these modules are built from a single C file. Rename the source files so they match the module names.

2023-03-20drm/bridge: imx8qxp-ldb: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-07-05drm: Remove linux/media-bus-format.h from drm_crtc.hVille Syrjälä
drm_crtc.h has no need for linux/media-bus-format.h, so don't include it. Avoids useless rebuilds of the entire universe when touching linux/media-bus-format.h. Quite a few placs do currently depend on linux/media-bus-format.h without actually including it directly. All of those need to be fixed up. v2: Deal with ingenic as well v3: Fix up mxsfb and remaining parts of imx Acked-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220630195114.17407-4-ville.syrjala@linux.intel.com
2022-06-20drm/bridge: imx: Add LDB support for i.MX8qxpLiu Ying
This patch adds a drm bridge driver for i.MX8qxp LVDS display bridge(LDB) which is officially named as pixel mapper. The LDB has two channels. Each of them supports up to 24bpp parallel input color format and can map the input to VESA or JEIDA standards. The two channels cannot be used simultaneously, that is to say, the user should pick one of them to use. Two LDB channels from two LDB instances can work together in LDB split mode to support a dual link LVDS display. The channel indexes have to be different. Channel0 outputs odd pixels and channel1 outputs even pixels. This patch supports the LDB single mode and split mode.
