From 86be408bfbd846fab3c4ac21d6f9298bd2e4b790 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Wed, 18 Jun 2014 17:29:32 +0200 Subject: clk: Support for clock parents and rates assigned from device tree This patch adds helper functions to configure clock parents and rates as specified through 'assigned-clock-parents', 'assigned-clock-rates' DT properties for a clock provider or clock consumer device. The helpers are now being called by the bus code for the platform, I2C and SPI busses, before the driver probing and also in the clock core after registration of a clock provider.
