Merge tag 'riscv-for-linus-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt:
- A pair of device tree fixes for the Polarfire SOC
- A fix to avoid overflowing the PMU counter array when firmware
incorrectly reports the number of supported counters, which manifests
on OpenSBI versions prior to 1.1
* tag 'riscv-for-linus-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux:
perf: RISC-V: fix access beyond allocated array
riscv: dts: microchip: use an mpfs specific l2 compatible
dt-bindings: riscv: sifive-l2: add a PolarFire SoC compatible
