@ -5,24 +5,6 @@ Todo:
|
|||
and added to the build.
|
||||
- testing?
|
||||
- handle churn in v4l layer.
|
||||
- Some features for wis-tw2804 subdev control (comb filter,motion detector sensitive & mask,more over...)
|
||||
- go7007-v4l2.c need rewrite with new v4l2 style without nonstandart IO controls (set detector & bitrate)
|
||||
|
||||
05/05/2012 3.4.0-rc+:
|
||||
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.x branch in initialization v4l2_subdev parts.
|
||||
now i2c_get_clientdata(...) contains v4l2_subdev struct instead non standart wis_tw2804 struct
|
||||
|
||||
Adds:
|
||||
- Additional chipset wis2804 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 up when s_stream(...,1), down otherwise in wis-tw2804 module
|
||||
