The first two patches update the LD9040 panel driver so that it looks much better, and supports setting the backlight. The third patch fixes the size of the panel in the Device Tree. The previous values were completely bogus and caused Phosh (PmOS' UI) to display tiny icons and text as it thought the DPI was much lower. Changes since V1: [1/3]: Remove spurious new line [2/3]: Remove .get_brightness() callback, use bl_get_data() and backlight_get_brightness() Cheers, -Paul Paul Cercueil (3): drm/panel: ld9040: Use better magic values drm/panel: ld9040: Register a backlight device ARM: dts: exynos/i9100: Fix LCD screen's physical size arch/arm/boot/dts/exynos4210-i9100.dts | 4 +- drivers/gpu/drm/panel/panel-samsung-ld9040.c | 42 +++++++++++++++++--- 2 files changed, 38 insertions(+), 8 deletions(-) Reviewed-by: Sam Ravnborg Acked-by: Sam Ravnborg
