From b75c015143a4a6021731ff3e36718896381be94f Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Tue, 19 Apr 2011 08:33:45 +0200 Subject: ARM i.MX: Add common clock support for 2bit gate This gate consists of two bits: 0b00: clk disabled 0b01: clk enabled in run mode and disabled in sleep mode 0b11: clk enabled Currently only disabled and enabled are supported. As it's unlikely that we find something like this in another SoC create a i.MX specific clk helper for this.
