Subject: [PATCH v6 00/26] Add perf support to the rockchip-dfi driver

This contains only small changes to the last version, but in one case
a really important one: As Sebastian noted there is sometimes wrong data
reported. This is fixed in this version.

Other than that there are only small changes, see below in the changelog.

Overall I think this series this series is ready for primetime now.

Sascha

Changes since v5:
- Add missing initialization of &dfi->last_perf_count which resulted
  in wrong data sometimes
- Drop interrupt-names property from binding
- Add patch to add rockchip,rk3588-pmugrf to dt-bindings
- Add more reviewed-by tags

Changes since v4:
- Add device tree changes for RK3588
- Use seqlock to protect perf counter values from hrtimer
- Unconditionally enable DFI when perf is enabled
- Bring back changes to dts/binding patches that were lost in v4

Changes since v3:
- Add RK3588 support

Changes since v2:
- Fix broken reference to binding
- Add Reviewed-by from Rob

Changes since v1:
- Fix example to actually match the binding and fix the warnings resulted thereof
- Make addition of rockchip,rk3568-dfi an extra patch
