This issuses applyed only for Adlink MPG24 board with go7007
& wis2804, all whese changes was tested for continuos
load&restart mode
This is minimal changes needed for start up go7007&wis2804 to work correctly
in 3.4 branch
Changes:
- When go7007 reset device, i2c was not worked (need rewrite GPIO5)
- As wis2804 has i2c_addr=0x00/*really*/, so Need set I2C_CLIENT_TEN flag for validity
- some main nonzero initialization, rewrites with kzalloc instead kmalloc
- STATUS_SHUTDOWN was placed in incorrect place, so if firmware wasn`t loaded, we
failed v4l2_device_unregister with kernel panic (OOPS)
- some new v4l2 style features as call_all(...s_stream...) for using subdev calls
- wis-tw2804.ko module code was incompatible with 3.4 branch in initialization v4l2_subdev parts.
now i2c_get_clientdata(...) contains v4l2_subdev struct instead non standart wis_tw2804 struct
Adds:
- Additional chipset tw2804 controls with: gain,auto gain,inputs[0,1],color kill,chroma gain,gain balances,
for all 4 channels (from tw2804.pdf)
- Power control for each 4 ADC (tw2804) up when s_stream(...,1), down otherwise
