[PATCH 4.2 244/258] clk: ti: clk-7xx: Remove hardwired ABE clock configuration

From: Greg Kroah-Hartman
Date: Sat Oct 17 2015 - 23:35:46 EST


4.2-stable review patch. If anyone has any objections, please let me know.

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

From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>

commit 4b3061b39132cba0c31b0eb767a9faeedf9437fc upstream.

The ABE related clocks should be configured via DT and not have it wired
inside of the kernel.

Fixes: a74c52def9ab ("clk: ti: clk-7xx: Correct ABE DPLL configuration")
