2010-02-26V4L/DVB: gspca_pac7302: much improved exposure controlHans de Goede
My experience with fixing up the controls for the PAS sensors in sonixb, has lead me to re-investigate the exposure control for the pac7302. I've now found a regular exposure register in register bank 3 (which seems to be the sensor registers bank), and with this added a proper fine grained exposure control. This patch also updates the do_autogain function to work properly with this new finer grained control.

2010-02-26V4L/DVB (13926): gspca - pac7302: Fix a random USB error.Jean-Francois Moine
When loading the register 0x49 of the page 3, the usb_control_msg() sometimes fails with error -71 or -62. This change skips loading the register 0x48.

2009-12-05V4L/DVB (13419): gspca - pac7302: Add debug register write interface.Márton Németh
Add debug register write interface to pac7302 to be able to set for example the edge detect mode (bit 2 register 0x55) or the test pattern (bit 0..3, register 0x72) and test overlay (bit 4, register 0x72) from the user space. Only write of register page 0 is supported by this patch.

2009-12-05V4L/DVB (13300): gspca - pac7302/pac7311: Separate the two subdrivers.Marton Nemeth
All PAC7311 specific functions remain in pac7311.c. All PAC7302 specific functions are moved to pac7302.c. The USB device table is also divided into two parts. This makes it possible to remove the sensor specific decisions from different functions and also remove sensor infromation from the USB device table. The common functions are just copied to both subdrivers. These common functions can be separated later to a common file or helper module.
