Subject[PATCH 2/3 v2] clk: qoriq: remove legacy bindings and add more compatibles
Date
From: Yuantian Tang <andy.tang@nxp.com>

The new bindings will be used, so delete the old bindings.
Add more SOC compatibles as needed as well.

Signed-off-by: Tang Yuantian <andy.tang@nxp.com>

-4. Legacy Child Nodes
-
-NOTE: These nodes are deprecated. Kernels should continue to support
-device trees with these nodes, but new device trees should not use them.
-
-Most of the bindings are from the common clock binding[1].
- [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : Should include one of the following:
- * "fsl,qoriq-core-pll-1.0" for core PLL clocks (v1.0)
- * "fsl,qoriq-core-pll-2.0" for core PLL clocks (v2.0)
- * "fsl,qoriq-core-mux-1.0" for core mux clocks (v1.0)
- * "fsl,qoriq-core-mux-2.0" for core mux clocks (v2.0)
- * "fsl,qoriq-sysclk-1.0": for input system clock (v1.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-sysclk-2.0": for input system clock (v2.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-platform-pll-1.0" for the platform PLL clock (v1.0)
- * "fsl,qoriq-platform-pll-2.0" for the platform PLL clock (v2.0)
-- #clock-cells: From common clock binding. The number of cells in a
- clock-specifier. Should be <0> for "fsl,qoriq-sysclk-[1,2].0"
- clocks, or <1> for "fsl,qoriq-core-pll-[1,2].0" clocks.
- For "fsl,qoriq-core-pll-[1,2].0" clocks, the single
- clock-specifier cell may take the following values:
- * 0 - equal to the PLL frequency
- * 1 - equal to the PLL frequency divided by 2
- * 2 - equal to the PLL frequency divided by 4
-
-Recommended properties:
-- clocks: Should be the phandle of input parent clock
-- clock-names: From common clock binding, indicates the clock name
-- clock-output-names: From common clock binding, indicates the names of
- output clocks
-- reg: Should be the offset and length of clock block base address.
- The length should be 4.
