From f2a4c59df62f4493c7cf7dfd349ec66bdd4b9fec Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Mon, 1 Feb 2010 17:38:53 -0500 Subject: [PATCH] DaVinci - Adding platform & board changes for vpfe capture on DM365 This patch adds following changes:- 1) add sub device configuration data for TVP5146 used by vpfe capture 2) registers platform devices for vpfe_capture, isif and vpss 3) defines hardware resources for the devices listed under 2) 4) defines clock aliase for isif driver 5) adding setup_pinmux() for isif Signed-off-by: Murali Karicheri Signed-off-by: Kevin Hilman --- arch/arm/mach-davinci/board-dm365-evm.c | 71 ++++++++++++++ arch/arm/mach-davinci/dm365.c | 102 ++++++++++++++++++++- arch/arm/mach-davinci/include/mach/dm365.h | 2 + 3 files changed, 174 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-davinci/board-dm365-evm.c b/arch/arm/mach-davinci/board-dm365-evm.c index b476395d2cd..38e9033d2e8 100644 --- a/arch/arm/mach-davinci/board-dm365-evm.c +++ b/arch/arm/mach-davinci/board-dm365-evm.c @@ -37,6 +37,8 @@ #include #include +#include + static inline int have_imager(void) { /* REVISIT when it's supported, trigger via Kconfig */ @@ -306,6 +308,73 @@ static void dm365evm_mmc_configure(void) davinci_cfg_reg(DM365_SD1_DATA0); } +static struct tvp514x_platform_data tvp5146_pdata = { + .clk_polarity = 0, + .hs_polarity = 1, + .vs_polarity = 1 +}; + +#define TVP514X_STD_ALL (V4L2_STD_NTSC | V4L2_STD_PAL) +/* Inputs available at the TVP5146 */ +static struct v4l2_input tvp5146_inputs[] = { + { + .index = 0, + .name = "Composite", + .type = V4L2_INPUT_TYPE_CAMERA, + .std = TVP514X_STD_ALL, + }, + { + .index = 1, + .name = "S-Video", + .type = V4L2_INPUT_TYPE_CAMERA, + .std = TVP514X_STD_ALL, + }, +}; + +/* + * this is the route info for connecting each input to decoder + * ouput that goes to vpfe.
