Merge tag 'v6.7-rockchip-dts64-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/dt

One new board the Turing RK1 system on module.
Support for DFI (DDR performance monitoring) for rk3588, rk3568 and an
enable-fix for rk3399 as well as some small fixups for the RGB30 handheld
(non-existent uart and better vpll frequency).

* tag 'v6.7-rockchip-dts64-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  arm64: dts: rockchip: Add Turing RK1 SoM support
  dt-bindings: arm: rockchip: Add Turing RK1
