2012-05-22cg2900: Support new connectivity chipsHemant Gupta
This patch adds support for new connectivity combo chips. Support is added for CG2905 and CG2910 chips firmware downloading. CG2910 supports NFC, therefore a new HCI H4 channel is added.

2012-05-22CG2900: changing sleep timersNitin Dhingra
Reducing the sleep timer value from 10 sec to 150ms, to put CG29XX chip to sleep. and after 50ms checking CG29XX has gone to sleep then release the wakelocks for system to go in sleep mode. This will decrease the power consumption greatly.

2012-05-22CG2900: Fix timings for CG29XX during breakNitin Dhingra
In Reference to CG29x0 low power mode control document, there are some fixes required in CG2900 protocol driver for break conditions. 1)Pre-break - 900usec - This is the minimal time before Host sending a break after it completes sending data on Tx_Host line. 2)in-break - 5msec - This is the minimal time that Host should maintain the break. 3)post-break - 200usec - This is the minimal time before Host starting sending data on Tx_Host line after it exits break.

2012-05-22cg2900: Code optimizations for CG2900 init timenitin.dhingra
Some general code optimizations during intialization done. Also we are releasing clock user like WLAN earlier as READ SELF TEST is not required for WLAN functionality. All these optimizations are done to reduce CG2900 init time which will also impact WLAN start-up time. Also ESD Clamp workaround has been removed from the code completely. This is not required anymore.
