From de956c1e0f89413a3837b642d592e2dff3e3eb78 Mon Sep 17 00:00:00 2001 From: Hartmut Hackmann Date: Fri, 27 Apr 2007 12:31:12 -0300 Subject: [PATCH] V4L/DVB (5313): Added a config entry and a gpio function pointer to tuner struct These entries mainly are to support configurations of the tda827x silicon tuner with a preamplifier. The values can be set throgh the attach inform or through the extended TUNER_SET_TYPE_ADDR client call. The function pointer will only be updated if the parameter is not NULL. Since a typecast is necessary to set the pointer, i added a typedef for this pointer (tuner_gpio_func_t) in tuner.h Signed-off-by: Hartmut Hackmann Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/saa7134/saa7134-cards.c | 3 ++- drivers/media/video/saa7134/saa7134-i2c.c | 2 ++ drivers/media/video/saa7134/saa7134.h | 1 + drivers/media/video/tuner-core.c | 24 ++++++++++++++------- include/media/tuner.h | 7 ++++++ 5 files changed, 28 insertions(+), 9 deletions(-) diff --git a/drivers/media/video/saa7134/saa7134-cards.c b/drivers/media/video/saa7134/saa7134-cards.c index 89f32107f46b..4399d1371cc1 100644 --- a/drivers/media/video/saa7134/saa7134-cards.c +++ b/drivers/media/video/saa7134/saa7134-cards.c @@ -2543,11 +2543,12 @@ struct saa7134_board saa7134_boards[] = { .name = "Philips Tiger reference design", .audio_clock = 0x00187de7, .tuner_type = TUNER_PHILIPS_TDA8290, + .tuner_config = 0, .radio_type = UNSET, .tuner_addr = ADDR_UNSET, .radio_addr = ADDR_UNSET, .mpeg = SAA7134_MPEG_DVB, - .gpiomask = 1 << 21, + .gpiomask = 0x0200000, .inputs = {{ .name = name_tv, .vmux = 1, diff --git a/drivers/media/video/saa7134/saa7134-i2c.c b/drivers/media/video/saa7134/saa7134-i2c.c index cce8da6a4f94..62c107e7759d 100644 --- a/drivers/media/video/saa7134/saa7134-i2c.c +++ b/drivers/media/video/saa7134/saa7134-i2c.c @@ -370,6 +370,8 @@ static int attach_inform(struct i2c_client *client) tun_setup.type = tuner;
