Hi All, The dsi + panel is a parental relationship, so OF grpah is not needed. Therefore, the current dsi_parse_dt function will throw an error, because there is no linked OF graph for case such as fimd + dsi + panel. So the 1/5 patch parse the Pll, burst and esc clock frequency properties in dsi_parse_dt and modified to create a bridge_node only if there is an OF graph associated with dsi. Also fixed the dts, which depend on the 1/5 patch. So removed the ports node and move burst and esc clock frequency properties to the parent (DSI node). Changes for V4: - Squashed patch 2, 3 and 4. - Added Reviewed-by: Andrzej Hajda <a.hajda@xxxxxxxxxxx> on all patches. Changes for V3: - Split the patches considering the bisectability problem. Changes for V2: - Added the clear explanation for commit. (1/5 patch) - Fixed it to the same subject as the actual work. (2/5 ~ 5/5 patches) Best Regards, Hoegeun Hoegeun Kwon (5): arm64: dts: exynos: Add the burst and esc clock frequency properties to DSI node arm: dts: Add the burst and esc clock frequency properties to DSI node drm/exynos: dsi: Fix the parse_dt function arm64: dts: exynos: Remove the OF graph from DSI node arm: dts: Remove the OF graph from DSI node arch/arm/boot/dts/exynos3250-rinato.dts | 23 ++-------------- arch/arm/boot/dts/exynos4210-trats.dts | 23 ++-------------- arch/arm/boot/dts/exynos4412-trats2.dts | 23 ++-------------- .../boot/dts/exynos/exynos5433-tm2-common.dtsi | 16 ++--------- drivers/gpu/drm/exynos/exynos_drm_dsi.c | 32 ++++++---------------- 5 files changed, 16 insertions(+), 101 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
