From 0124d3c9c8071f1994a85d9f9973129efd6e044d Mon Sep 17 00:00:00 2001 From: Hartmut Hackmann Date: Tue, 23 Jan 2007 00:14:25 +0100 Subject: Added a config entry and a gpio function pointer to the tuner struct From: Hartmut Hackmann 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 --- linux/include/media/tuner.h | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'linux/include/media/tuner.h') diff --git a/linux/include/media/tuner.h b/linux/include/media/tuner.h index 947b32366..153e2a6ea 100644 --- a/linux/include/media/tuner.h +++ b/linux/include/media/tuner.h @@ -173,10 +173,15 @@ enum tuner_mode { when the tuner is set to TV mode. */ +/* allows to access the GPIOs of the host (pci bridge) */ +typedef void (*tuner_gpio_func_t) (void *dev, int bit_no,int value); + struct tuner_setup { unsigned short addr; /* I2C address */ unsigned int type; /* Tuner type */ unsigned int mode_mask; /* Allowed tuner modes */ + unsigned int config; /* configuraion for more complex tuners */ + tuner_gpio_func_t gpio_func; }; struct tuner { @@ -210,6 +215,8 @@ struct tuner { unsigned char tda827x_addr; unsigned char tda827x_ver; unsigned int sgIF; + unsigned int config; + tuner_gpio_func_t gpio_func; /* function ptrs */ void (*set_tv_freq)(struct i2c_client *c, unsigned int freq); -- cgit v1.2.3
