I'm developing TW9900 Driver on linux-3.10.53.
I will connect Analog CAM to TW9900 and TW9900 to imx6.
Analog CAM ====nstc====>Tw9900 ====BT656 =====> imx6 CSI1
I found tw9910.c in <linux-3.10.53>/drivers/media/i2c/soc_camera.
I revised device tree.
device_drivers-> multimedia_support --> sensors used on soc_camera_driver -> tw9910 support <*>
so, I tested tw9910 driver.
i founded tw9910 driver error message.
"tw9910 2-0044 : TW9910: missing platform data!
It is tw9910 dirver probe source.
I think soc_camera_i2c_to_desc(client) function returns NULL.
Why return valuse is NULL?
How resolve this problems??
Is it right to use this video decoder ?
i found something, <linux-3.10.53>/drivers/media/platform/mxc/capture/adv7180.c
adv7180 is video decoder.
what is different between soc camera and video decoder?
