From 589541c0bfb1426ad39c7b59c0372346bcf84229 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 21 Feb 2011 08:42:36 +0200 Subject: [PATCH] omap: rx51: Add SI4713 FM transmitter Add SI4713 FM transmitter supplies, platform data and setup to RX-51/N900. It is connected to line output signals of TLV320AIC34 codec A part. Driver can be either built-in or a module. It can be tuned with v4l2-ctl from ivtv-utils. Following examples illustrate the use of it: v4l2-ctl -d /dev/radio0 --set-ctrl=mute=0 (power up) v4l2-ctl -d /dev/radio0 -f 107900 (tune 107.9 MHz) v4l2-ctl -d /dev/radio0 --set-ctrl=mute=1 (power down) Signed-off-by: Jarkko Nikula Signed-off-by: Tony Lindgren --- arch/arm/mach-omap2/board-rx51-peripherals.c | 44 ++++++++++++++++++++ 1 file changed, 44 insertions(+) diff --git a/arch/arm/mach-omap2/board-rx51-peripherals.c b/arch/arm/mach-omap2/board-rx51-peripherals.c index e75e240cad67..d0998f812693 100644 --- a/arch/arm/mach-omap2/board-rx51-peripherals.c +++ b/arch/arm/mach-omap2/board-rx51-peripherals.c @@ -36,6 +36,8 @@ #include #include +#include +#include #include <../drivers/staging/iio/light/tsl2563.h> @@ -47,6 +49,8 @@ #define RX51_WL1251_POWER_GPIO 87 #define RX51_WL1251_IRQ_GPIO 42 +#define RX51_FMTX_RESET_GPIO 163 +#define RX51_FMTX_IRQ 53 /* list all spi devices here */ enum { @@ -357,10 +361,14 @@ static struct regulator_consumer_supply rx51_vio_supplies[] = { REGULATOR_SUPPLY("DVDD", "2-0018"), REGULATOR_SUPPLY("IOVDD", "2-0019"), REGULATOR_SUPPLY("DVDD", "2-0019"), + /* Si4713 IO supply */ + REGULATOR_SUPPLY("vio", "2-0063"), }; static struct regulator_consumer_supply rx51_vaux1_consumers[] = { REGULATOR_SUPPLY("vdds_sdi", "omapdss"), + /* Si4713 supply */ + REGULATOR_SUPPLY("vdd", "2-0063"), }; static struct regulator_consumer_supply rx51_vdac_supply[] = { @@ -511,6 +519,41 @@ static struct regulator_init_data rx51_vio = { .consumer_supplies = rx51_vio_supplies, }; +static struct si4713_platform_data rx51_si4713_i2c_data __initdata_or_module = { + .gpio_reset = RX51_FMTX_RESET_GPIO, +}; + +static struct i2c_board_info rx51_si4713_board_info __initdata_or_module = { + I2C_BOARD_INFO("si4713", SI4713_I2C_ADDR_BUSEN_HIGH), + .platform_data = &rx51_si4713_i2c_data, +}; + +static struct radio_si4713_platform_data rx51_si4713_data __initdata_or_module = { + .i2c_bus = 2, + .subdev_board_info = &rx51_si4713_board_info, +}; + +static struct platform_device rx51_si4713_dev __initdata_or_module = { + .name = "radio-si4713", + .id = -1, + .dev = { + .platform_data = &rx51_si4713_data, + }, +}; + +static __init void rx51_init_si4713(void) +{ + int err; + + err = gpio_request_one(RX51_FMTX_IRQ, GPIOF_DIR_IN, "si4713 irq"); + if (err) { + printk(KERN_ERR "Cannot request si4713 irq gpio. %d\n", err); + return; + } + rx51_si4713_board_info.irq = gpio_to_irq(RX51_FMTX_IRQ); + platform_device_register(&rx51_si4713_dev); +} + static int rx51_twlgpio_setup(struct device *dev, unsigned gpio, unsigned n) { /* FIXME this gpio setup is just a placeholder for now */ @@ -921,6 +964,7 @@ void __init rx51_peripherals_init(void) board_smc91x_init(); rx51_add_gpio_keys(); rx51_init_wl1251(); + rx51_init_si4713(); spi_register_board_info(rx51_peripherals_spi_board_info, ARRAY_SIZE(rx51_peripherals_spi_board_info));
