[PATCH 0/2] arm64: dts: r8a77965: salvator-x(s): Enable s2ram and PMIC

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch populates the placeholders in the R-Car M3-N DTS file for the
IIC Bus Interface for DVFS (IIC for DVFS) and Interrupt Controller for
External Devices (INTC-EX) device nodes.

After applying the first patch, you can start using s2ram (PSCI
suspend), like on other Salvator-X(S) boards
(https://elinux.org/R-Car/Boards/Salvator-XS#PSCI_System_Suspend).

The second patch enables dependencies for the BD9571MWV PMIC device,
which is described in salvator-common.dtsi. Note that operation still
depends on "[PATCH] pinctrl: sh-pfc: r8a77965: Add support for INTC-EX
IRQ pins".

Thanks!

[PATCH 1/2] arm64: dts: r8a77965: Add IIC-DVFS device node

[Geert Uytterhoeven]

Populate the device node for the IIC Bus Interface for DVFS (IIC for
DVFS) on R-Car M3-N, and add an alias to fix its bus number.

[PATCH 2/2] arm64: dts: r8a77965: Add INTC-EX device node

[Geert Uytterhoeven]

Populate the device node for the Interrupt Controller for External
Devices (INTC-EX) on R-Car M3-N, which serves external IRQ pins
IRQ[0-5].
