[PATCH v6 0/5] Add MIPI rx DPI support
Hi all, this patch series implement MIPI rx DPI feature. Please help to review. This is the v6 version, any mistakes, please let me know, I'll fix it in the next series. Change history: v6: Fix kernel robot compile warning v5: Fix Rob Herring, Hsin-Yi, Robert Foss comments - Rebase code on the branch 'drm-misc-next', refer video-interfaces.yaml - Seprate HDCP function to a new patch - Fix driver not correctly get 'bus-type' 'data-lanes' - Add audio HDMI codec function support v4: Fix Rob Herring comment - Rebase code on the branch 'drm-misc-next' - Change 'analogix,hdcp-support' type to boolean v3: Fix Rob Herring, Dan Carpenter, Nicolas comment - Split the patch, fix not correct return data - Fix several coding format - Split DP tx swing register setting to two property - Add HDCP support vender flag - remove 'analogix,swing-setting' and 'analogix,mipi-dpi-in' property v2: Fix Rob Herring comment - Fix yamllint warnings/errors in analogix,anx7625.yaml - Fix kernel robot compile warning v1: initial MIPI rx DPI feature support Xin Ji (5): dt-bindings:drm/bridge:anx7625:add vendor define flags drm/bridge: anx7625: fix not correct return value drm/bridge: anx7625: add MIPI DPI input feature support drm/bridge: anx7625: add HDCP support drm/bridge: anx7625: add HDMI audio function .../display/bridge/analogix,anx7625.yaml | 58 +- drivers/gpu/drm/bridge/analogix/anx7625.c | 603 -- drivers/gpu/drm/bridge/analogix/anx7625.h | 59 +- 3 files changed, 667 insertions(+), 53 deletions(-) -- 2.25.1 ___ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
