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 has 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 interface 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. regards Philipp --- 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 | 614 ++++++++++++++++++++++++++++++++++++ 12 files changed, 758 insertions(+), 25 deletions(-) _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
