Cover letter [PATCH 0/5] ARM: shmobile: R-Mobile APE6 / R-Car Gen2: Use "arm,gic-400"
Quoted 15 lines · 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!

    or from U-Boot using "md 0xf1001008 1",

[2] Backporter's note: since commit 144cb08864ed44be ("irqchip: gic: Add binding probe for ARM GIC400").

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.
