From b6f5128459a40410f9afefddc0ad688ea5b22c28 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Sat, 20 Feb 2016 13:24:26 +0200 Subject: clk: ti: dpll: convert DPLL support code to use clk_hw instead of clk ptrs Convert DPLL support code to use clk_hw pointers for reference and bypass clocks. This allows us to use clk_hw_* APIs for accessing any required parameters for these clocks, avoiding some locking problems at least with DPLL enable code; this used clk_get_rate which uses mutex but isn't good under clk_enable / clk_disable.

Along with the above mentioned Kconfig changes it seems appropriate to also rename files.
