From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx> Add mx6 hdmi transmitter support. Original work has been done by Sascha Hauer and Tony Prisk. Special thanks to Russell King for his carefully review, many bug fixes and testing of the mx6 HDMI driver. Tested on the following boards: - mx6q sabresd - mx6dl sabresd - mx6solo wandboard Signed-off-by: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx> Signed-off-by: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx> --- This patch applies against 3.12-rc7. Also, the following patch needs to be applied in order to get good HDMI quality on mx6solo: https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit/?h=staging-next&id=f0ac9bebf19001f38afbb93e2dc719a15dfb75e5 Changes since v3: - Fix the PLL wait lock loop (Russell) - Use vmode->mpixelclock = mode->clock * 1000 (Russell) - vsync len is in lines not pixel clocks (Russell) - get rid of pointless fb_reg (Russell) - get rid of clk manipulations in imx_hdmi_fb_register - minor cleanup (Russell) - Added Russell's Signed-off-by tag drivers/staging/imx-drm/Kconfig | 6 + drivers/staging/imx-drm/Makefile | 1 + drivers/staging/imx-drm/imx-hdmi.c | 1916 +++++++++++++++++++++++++++ drivers/staging/imx-drm/imx-hdmi.h | 1032 +++++++++++++++ include/linux/mfd/syscon/imx6q-iomuxc-gpr.h | 1 + 5 files changed, 2956 insertions(+) create mode 100644 drivers/staging/imx-drm/imx-hdmi.c create mode 100644 drivers/staging/imx-drm/imx-hdmi.h diff --git a/drivers/staging/imx-drm/Kconfig b/drivers/staging/imx-drm/Kconfig index 394254f..9c85077 100644 --- a/drivers/staging/imx-drm/Kconfig +++ b/drivers/staging/imx-drm/Kconfig @@ -52,3 +52,9 @@ config DRM_IMX_IPUV3 depends on DRM_IMX_IPUV3_CORE help Choose this if you have a i.MX5 or i.MX6 processor. + +config DRM_IMX_HDMI + tristate "Freescale i.MX DRM HDMI" + depends on DRM_IMX + help + Choose this if you want to use HDMI on i.MX6. diff --git a/drivers/staging/imx-drm/Makefile b/drivers/staging/imx-drm/Makefile index bfaf693..79a5588 100644 --- a/drivers/staging/imx-drm/Makefile +++ b/drivers/staging/imx-drm/Makefile @@ -9,3 +9,4 @@ obj-$(CONFIG_DRM_IMX_LDB) += imx-ldb.o obj-$(CONFIG_DRM_IMX_FB_HELPER) += imx-fbdev.o obj-$(CONFIG_DRM_IMX_IPUV3_CORE) += ipu-v3/ obj-$(CONFIG_DRM_IMX_IPUV3) += ipuv3-crtc.o +obj-$(CONFIG_DRM_IMX_HDMI) += imx-hdmi.o diff --git a/drivers/staging/imx-drm/imx-hdmi.c b/drivers/staging/imx-drm/imx-hdmi.c new file mode 100644 index 0000000..5645b12 --- /dev/null +++ b/drivers/staging/imx-drm/imx-hdmi.c @@ -0,0 +1,1916 @@ +/* + * Copyright (C) 2011-2013 Freescale Semiconductor, Inc. + * + * This program is free software;
