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
