[PATCH] clk: sirf: add CSR atlas7 clk and reset support
Barry Song

Thu Dec 25 00:24:05 PST 2014
From: Zhiwu Song <Zhiwu.Song at csr.com>
the hardware node includes both clock and reset support, so it
is named as "car".
this patch implements Flexible clocks(mux, divider, gate), Selectable
clock(mux, divider, gate), root clock(gate),leaf clock(gate), others.
it also implements the reset controller functionality.

+* Clock and reset bindings for CSR atlas7
+
+Required properties:
+- compatible: Should be "sirf,atlas7-car"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- #reset-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell.
+The ID list atlas7_clks defined in drivers/clk/sirf/clk-atlas7.c
+
+The reset consumer should specify the desired reset by having the reset
+ID in its "reset" phandle cell.
+The ID list atlas7_reset_unit defined in drivers/clk/sirf/clk-atlas7.c
+
+Examples:
+
+timer at 10dc0000 {
+ compatible = "sirf,macro-tick";
+ reg = <0x10dc0000 0x1000>;
+ clocks = <&car 54>;
+ interrupts = <0 0 0>,
+ <0 1 0>,
+ <0 2 0>,
+ <0 49 0>,
+ <0 50 0>,
+ <0 51 0>;
+};
+
+uart1: uart at 18020000 {

+ reg = <0x18020000 0x1000>;
+ clocks = <&clks 95>;
+ interrupts = <0 18 0>;
