TI 工程师你好,你们上次给我发了一份TVP5158在DM6467下的驱动--DM365_DVR_DVSDK3_00.02.00.00\mcvip_tvp5158,,但在i2c-davinci.c文件中的#include "i2c-davinci.h",但搜索没有发现i2c-davinci.h,能否发一下i2c-davinci.h,谢谢了

太感谢了,大神,你有没有DM3730的I2C驱动呢,我现在开发包里没有找到针对DM3730的I2C总线/adapter的驱动。
在DM3730开发包DVSDK中的I2C总线驱动:i2c-davinci.c中有如下代码
static void disable_i2c_pins(void)
{
unsigned long flags;
local_irq_save(flags);
if (cpu_is_davinci_dm644x()) {
/* I2C clock on GPIO43, I2C data on GPIO44 */
gpio_direction_input(44);
gpio_direction_output(43, 0);
gpio_set_value(43, 1);
davinci_cfg_reg(DM644X_GPIO43_44);
} else if (cpu_is_davinci_dm355()) {
/* I2C clock on GPIO14, I2C data on GPIO15 */
gpio_direction_input(15);
gpio_direction_output(14, 0);
gpio_set_value(14, 1);
davinci_cfg_reg(DM355_GPIO14);
davinci_cfg_reg(DM355_GPIO15);
}
local_irq_restore(flags);
}
这个代码中就是没有DM3730的相关信息,难道还要自己编写DM3730的I2C总线驱动吗?
