Merge "soc: ti: Keystone Navigator SOC driver updates for 3.20" from Santosh
Shilimkar:

Keystone Navigator SOC driver updates for 3.20

- Makefile tweak so that knav_qmss and knav_dma can be made loadable
	modules without depedency issues.
- Few more exports to support ARM allmodconfig.
- Marking knav_range_setup_acc_irq() local function as static.

* tag 'drivers-soc-ti' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone:
  soc: ti: knav_qmss_queue: change knav_range_setup_acc_irq to static
  soc: ti: knav_qmss_queue: makefile tweak to build as dynamic module
  soc: ti: knav_qmss_queue: export API calls for use by user driver
