[PATCH 0/5] ARM: shmobile: R-Mobile APE6 / R-Car Gen2: Use "arm,gic-400"

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This patch series replaces the "arm,cortex-a15-gic" compatible value for
the GIC device node by "arm,gic-400" in the R-Mobile APE6 and R-Car Gen2
device trees:
  - The R-Mobile APE6 documentation states it has a GIC-400,
  - The R-Car Gen2 is assumed to have a GIC-400, too.

The presence of a GIC-400 has been confirmed on APE6 and R-Car M2 by
reading the GICD_IIDR register[1], which reports 0x0200043b (GIC-400 0x02, ARM = 0x43b).

This change has no effect on runtime behavior, as currently[2] the GIC
driver treats both compatible values the same.

This has been tested on r8a73a4/ape6evm and r8a7791/koelsch.

Thanks for applying!

[PATCH 1/5] ARM: shmobile: r8a73a4 dtsi: Use "arm,gic-400" for GIC

[Geert Uytterhoeven]

Replace the "arm,cortex-a15-gic" compatible value for the GIC by
"arm,gic-400", as the documentation states it's a GIC-400.
This has been confirmed by reading the GICD_IIDR register, which reports
0x0200043b (GIC-400 = 0x02, ARM = 0x43b).

This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.

Thanks, I have queued these up after testing that the following still boot.

r8a73a4/ape6evm, r8a7790/lager r8a7791/koelsch, r8a7794/alt

I am unable to test the r8a7794/gose at this time.

Thanks, I have queued these up after testing that the following still boot.

r8a73a4/ape6evm, r8a7790/lager r8a7791/koelsch, r8a7794/alt
