Subject[PATCH 3.4 045/134] ath9k_hw: Enable hw PLL power save for AR9462
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>

commit 1680260226a8fd2aab590319da83ad8e610da9bd upstream.

This reduced the power consumption to half in full and network sleep.

[bwh: Backported to 3.2:
- INIT_INI_ARRAY macro requires an explicit size argument
- Remove the now-redundant macro PCIE_PLL_ON_CREQ_DIS_L1_2P0]
