From mboxrd@z Thu Jan 1 00:00:00 1970 From: khilman@baylibre.com (Kevin Hilman) Date: Wed, 7 Dec 2016 11:31:36 -0800 Subject: [PATCH v2 3/4] ARM: davinci: da8xx: add pdata-quirks, use for VPIF capture In-Reply-To: <20161207193137.27947-1-khilman@baylibre.com> References: <20161207193137.27947-1-khilman@baylibre.com> Message-ID: <20161207193137.27947-4-khilman@baylibre.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add pdata-quirks for da8xx DT platforms, which adds the 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/include/mach/common.h | 4 + arch/arm/mach-davinci/pdata-quirks.c | 155 ++++++++++++++++++++++++++++ 4 files changed, 162 insertions(+), 1 deletion(-) create mode 100644 arch/arm/mach-davinci/pdata-quirks.c diff --git a/arch/arm/mach-davinci/Makefile b/arch/arm/mach-davinci/Makefile index da4c336b4637..90d2e6e4d913 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 c9f7e9274aa8..69c8099de9f5 100644 --- a/arch/arm/mach-davinci/da8xx-dt.c +++ b/arch/arm/mach-davinci/da8xx-dt.c @@ -38,6 +38,7 @@ static struct of_dev_auxdata da850_auxdata_lookup[] __initdata = { NULL), OF_DEV_AUXDATA("ti,da830-mcasp-audio", 0x01d00000, "davinci-mcasp.0", NULL), OF_DEV_AUXDATA("ti,da850-aemif", 0x68000000, "ti-aemif", NULL), + OF_DEV_AUXDATA("ti,da850-vpif", 0x01e17000, "vpif", NULL), {} };
