[PATCH v2 2/4] ARM: imx6q: replace clk_register_clkdev with clock DT lookup

Shawn Guo shawn.guo at linaro.org
Wed Aug 22 09:36:28 EDT 2012


It really becomes an maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.

Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

+* Clock bindings for Freescale i.MX6 Quad
+
+Required properties:
+- compatible: Should be "fsl,imx6q-ccm"
+- reg: Address and length of the register set
+- interrupts: Should contain CCM interrupt
+- #clock-cells: Should be <1>
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell.  The following is a full list of i.MX6Q
+clocks and IDs.
