From mboxrd@z Thu Jan 1 00:00:00 1970 From: khilman@baylibre.com (Kevin Hilman) Date: Mon, 9 Jan 2017 12:55:30 -0800 Subject: [PATCH v2 5/6] ARM: davinci: da8xx: add pdata-quirks, use for VPIF capture In-Reply-To: <20170109205531.3435-1-khilman@baylibre.com> References: <20170109205531.3435-1-khilman@baylibre.com> Message-ID: <20170109205531.3435-6-khilman@baylibre.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org For da8xx DT platforms, use pdata-quirks to add legacy platform data for vpif_capture driver. Passing legacy platform_data is required until the V4L2 framework, and subdevice drivers (such as the tvp514x) grow a way of selecting input and output routing (c.f. V4L2 s_routing API) Signed-off-by: Kevin Hilman --- arch/arm/mach-davinci/Makefile | 2 +- arch/arm/mach-davinci/da8xx-dt.c | 2 + arch/arm/mach-davinci/pdata-quirks.c | 115 +++++++++++++++++++++++++++++++++++ 3 files changed, 118 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-davinci/Makefile b/arch/arm/mach-davinci/Makefile index 0a2e6da45f28..df96ca9eab6d 100644 --- a/arch/arm/mach-davinci/Makefile +++ b/arch/arm/mach-davinci/Makefile @@ -21,7 +21,7 @@ obj-$(CONFIG_AINTC) += irq.o obj-$(CONFIG_CP_INTC) += cp_intc.o # Board specific -obj-$(CONFIG_MACH_DA8XX_DT) += da8xx-dt.o +obj-$(CONFIG_MACH_DA8XX_DT) += da8xx-dt.o pdata-quirks.o obj-$(CONFIG_MACH_DAVINCI_EVM) += board-dm644x-evm.o obj-$(CONFIG_MACH_SFFSDR) += board-sffsdr.o obj-$(CONFIG_MACH_NEUROS_OSD2) += board-neuros-osd2.o diff --git a/arch/arm/mach-davinci/da8xx-dt.c b/arch/arm/mach-davinci/da8xx-dt.c index 9ee44da6eb7b..fe4a9e30d937 100644 --- a/arch/arm/mach-davinci/da8xx-dt.c +++ b/arch/arm/mach-davinci/da8xx-dt.c @@ -42,6 +42,7 @@ static struct of_dev_auxdata da850_auxdata_lookup[] __initdata = { OF_DEV_AUXDATA("ti,da830-ohci", 0x01e25000, "ohci-da8xx", NULL), OF_DEV_AUXDATA("ti,da830-musb", 0x01e00000, "musb-da8xx", NULL), OF_DEV_AUXDATA("ti,da830-usb-phy", 0x01c1417c, "da8xx-usb-phy", NULL), + OF_DEV_AUXDATA("ti,da850-vpif", 0x01e17000, "vpif", NULL), {} }; @@ -62,6 +63,7 @@ static void __init da850_init_machine(void) of_platform_default_populate(NULL, da850_auxdata_lookup, NULL); davinci_pm_init(); + pdata_quirks_init(); } static const char *const da850_boards_compat[] __initconst = { diff --git a/arch/arm/mach-davinci/pdata-quirks.c b/arch/arm/mach-davinci/pdata-quirks.c index 5b57da475065..142a2684c445 100644 --- a/arch/arm/mach-davinci/pdata-quirks.c +++ b/arch/arm/mach-davinci/pdata-quirks.c @@ -10,13 +10,122 @@ #include #include +#include + #include +#include struct pdata_init { const char *compatible; void (*fn)(void); }; +#if IS_ENABLED(CONFIG_VIDEO_DAVINCI_VPIF_CAPTURE) + +#define TVP5147_CH0 "tvp514x-0" +#define TVP5147_CH1 "tvp514x-1" + +/* VPIF capture configuration */ +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) + +static const struct vpif_input da850_ch0_inputs[] = { + { + .input = { + .index = 0, + .name = "Composite", + .type = V4L2_INPUT_TYPE_CAMERA, + .capabilities = V4L2_IN_CAP_STD, + .std = TVP514X_STD_ALL, + }, + .input_route = INPUT_CVBS_VI2B, + .output_route = OUTPUT_10BIT_422_EMBEDDED_SYNC, + .subdev_name = TVP5147_CH0, + }, +}; + +static const struct vpif_input da850_ch1_inputs[] = { + { + .input = { + .index = 0, + .name = "S-Video", + .type = V4L2_INPUT_TYPE_CAMERA, + .capabilities = V4L2_IN_CAP_STD, + .std = TVP514X_STD_ALL, + }, + .input_route = INPUT_SVIDEO_VI2C_VI1C, + .output_route = OUTPUT_10BIT_422_EMBEDDED_SYNC, + .subdev_name = TVP5147_CH1, + }, +}; + +static struct vpif_subdev_info da850_vpif_capture_sdev_info[] = { + { + .name = TVP5147_CH0, + .board_info = { + I2C_BOARD_INFO("tvp5146", 0x5d), + .platform_data = &tvp5146_pdata, + }, + }, + { + .name = TVP5147_CH1, + .board_info = { + I2C_BOARD_INFO("tvp5146", 0x5c), + .platform_data = &tvp5146_pdata, + }, + }, +}; + +static struct vpif_capture_config da850_vpif_capture_config = { + .subdev_info = da850_vpif_capture_sdev_info, + .subdev_count = ARRAY_SIZE(da850_vpif_capture_sdev_info), + .chan_config[0] = { + .inputs = da850_ch0_inputs, + .input_count = ARRAY_SIZE(da850_ch0_inputs), + .vpif_if = { + .if_type = VPIF_IF_BT656, + .hd_pol = 1, + .vd_pol = 1, + .fid_pol = 0, + }, + }, + .chan_config[1] = { + .inputs = da850_ch1_inputs, + .input_count = ARRAY_SIZE(da850_ch1_inputs), + .vpif_if = { + .if_type = VPIF_IF_BT656, + .hd_pol = 1, + .vd_pol = 1, + .fid_pol = 0, + }, + }, + .card_name = "DA850/OMAP-L138 Video Capture", +}; + +static void __init da850_vpif_legacy_init(void) +{ + int ret; + + /* LCDK doesn't have the 2nd TVP514x on CH1 */ + if (of_machine_is_compatible("ti,da850-lcdk")) + da850_vpif_capture_config.subdev_count = 1; + + /* EVM (UI card) uses i2c adapter 1 (not default: zero) */ + if (of_machine_is_compatible("ti,da850-evm")) + da850_vpif_capture_config.i2c_adapter_id = 1; + + ret = da850_register_vpif_capture(&da850_vpif_capture_config); + if (ret) + pr_warn("%s: VPIF capture setup failed: %d\n", + __func__, ret); +} +#endif + static void pdata_quirks_check(struct pdata_init *quirks) { while (quirks->compatible) { @@ -30,6 +139,12 @@ static void pdata_quirks_check(struct pdata_init *quirks) } static struct pdata_init pdata_quirks[] __initdata = { +#if IS_ENABLED(CONFIG_VIDEO_DAVINCI_VPIF_CAPTURE) + { "ti,da850-lcdk", da850_vpif_legacy_init, }, +#if defined(CONFIG_DA850_UI_SD_VIDEO_PORT) + { "ti,da850-evm", da850_vpif_legacy_init, }, +#endif +#endif { /* sentinel */ }, }; -- 2.9.3
