Message-Id: <1464071511-16363-2-git-send-email-LW@KARO-electronics.de> Date: Tue, 24 May 2016 08:31:49 +0200 From: Lothar Waßmann <LW@...O-electronics.de> To: David Airlie <airlied@...ux.ie>, Philipp Zabel <p.zabel@...gutronix.de>, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org Cc: Lothar Waßmann <LW@...O-electronics.de> Subject: [PATCHv2 1/3] drm/imx: imx-ldb: honor 'native-mode' property when selecting video mode from DT This patch allows to select a specific video mode from a list of modes defined in DT by setting the 'native-mode' property appropriately. This change does not affect the behaviour of existing platforms, since they either: - have just one display-timings subnode - have the native-mode property pointing to the first entry - let the bootloader select the appropriate timing Signed-off-by: Lothar Waßmann <LW@...O-electronics.de> --- drivers/gpu/drm/imx/imx-ldb.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/imx/imx-ldb.c b/drivers/gpu/drm/imx/imx-ldb.c index a58eee5..b2dc4df 100644 --- a/drivers/gpu/drm/imx/imx-ldb.c +++ b/drivers/gpu/drm/imx/imx-ldb.c @@ -25,6 +25,7 @@ #include <linux/mfd/syscon/imx6q-iomuxc-gpr.h> #include <linux/of_device.h> #include <linux/of_graph.h> +#include <video/of_display_timing.h> #include <video/of_videomode.h> #include <linux/regmap.h> #include <linux/videodev2.h> @@ -600,7 +601,8 @@ static int imx_ldb_bind(struct device *dev, struct device *master, void *data) channel->edid = kmemdup(edidp, channel->edid_len, GFP_KERNEL); } else if (!channel->panel) { - ret = of_get_drm_display_mode(child, &channel->mode, 0); + ret = of_get_drm_display_mode(child, &channel->mode, + OF_USE_NATIVE_MODE); if (!ret) channel->mode_valid = 1; } -- 2.1.4
