[PATCH 0/3] ARM: OMAP2+: hwmod: RTC: Add lock and unlock hooks

[Lokesh Vutla]

Some IP blocks like RTC, needs an additional unlocking mechanism for
writing to its registers. This patch adds optional lock and unlock
function pointers to the IP block's hwmod data which gets executed
before and after writing into IP sysconfig register.
And also hook lock and unlock functions to AMx3xx, DRA7 RTC hwmod data,
so that sysconfig registers are updated properly.

Tested on:
DRA7-evm: http://pastebin.ubuntu.com/11688889/
DRA72-evm: http://pastebin.ubuntu.com/11688901/
BeagleBoard-x15: http://pastebin.ubuntu.com/11688907/
BeagleBoneBlack: http://pastebin.ubuntu.com/11688923/ 
AM437x-gp-evm: http://pastebin.ubuntu.com/11689157/ (Used an out of tree patch to enable RTC)
