Merge tag 'renesas-dt2-for-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

Second Round of Renesas ARM Based SoC DT Updates for v4.8

* Use APMU on R-Car Gen2 and provide SMP for r8a7793 SoC
* Update console parameters to uniformly use chosen/stdout-path,
  serial0, not provide kernel unnecessary command line parameters
* Add DU pins to silk board
* Add support for blanche/r8a7792
* Name pfc subnodes after device name

DT bindings for the Renesas Advanced Power Management Unit



Renesas R-Car line of SoCs utilize one or more APMU hardware units

for CPU core power domain control including SMP boot and CPU Hotplug.



Required properties:



- compatible: Should be "renesas,<soctype>-apmu", "renesas,apmu" as fallback.

	      Examples with soctypes are:

		- "renesas,r8a7790-apmu" (R-Car H2)

		- "renesas,r8a7791-apmu" (R-Car M2-W)

		- "renesas,r8a7792-apmu" (R-Car V2H)

		- "renesas,r8a7793-apmu" (R-Car M2-N)

		- "renesas,r8a7794-apmu" (R-Car E2)



- reg: Base address and length of the I/O registers used by the APMU.



- cpus: This node contains a list of CPU cores, which should match the order

  of CPU cores used by the WUPCR and PSTR registers in the Advanced Power

  Management Unit section of the device's datasheet.





Example:



This shows the r8a7791 APMU that can control CPU0 and CPU1.



	apmu@e6152000 {

		compatible = "renesas,r8a7791-apmu", "renesas,apmu";

		reg = <0 0xe6152000 0 0x188>;

		cpus = <&cpu0 &cpu1>;
