Hi, the following patches add support for LVDS displays on i.MX53 and i.MX6q boards. The clock patches are needed because the LVDS serial clock needs to be in lockstep with the IPU display interface clock providing the pixel data. A fixed factor of 7:1 (or 3.5:1 in dual link mode) needs to be maintained. This is achieved on i.MX by clocking the LDB DI clock directly from a PLL, and manually setting the 3.5/7:1 divider depending on dual/single link mode. The IPU display interface clock is then sourced from the divided LDB clock. Changes since v1: - Added device-tree bindings documentation - Dropped remains of GPIO handling from LDB driver, sorry about that regards Philipp --- .../devicetree/bindings/staging/imx-drm/ldb.txt | 99 ++++ arch/arm/boot/dts/imx51.dtsi | 2 + arch/arm/boot/dts/imx53.dtsi | 34 ++ arch/arm/boot/dts/imx6q.dtsi | 17 + arch/arm/boot/dts/imx6qdl.dtsi | 26 + arch/arm/mach-imx/clk-imx51-imx53.c | 19 +- arch/arm/mach-imx/clk-imx6q.c | 43 +- arch/arm/mach-imx/clk.h | 17 + arch/arm/mach-imx/common.h | 1 + arch/arm/mach-imx/mach-imx6q.c | 2 +- drivers/staging/imx-drm/Kconfig | 7 + drivers/staging/imx-drm/Makefile | 1 + drivers/staging/imx-drm/imx-ldb.c | 611 +++++++++++++++++++++ 13 files changed, 854 insertions(+), 25 deletions(-) _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
