Merge tag 'v6.7-rockchip-dts32-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/dt

Someone resurrected a rk3128 board and provided actual SMP support
for it. Of course firmware for that SoC does not come with TF-A so
it's the old-style SMP the older arm32 Rockchip SoCs use.

And additionally the rv1126 got pwm support.

* tag 'v6.7-rockchip-dts32-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  ARM: dts: rockchip: Switch to operating-points-v2 for RK3128's CPU
  ARM: dts: rockchip: Enable SMP bring-up for RK3128
  ARM: dts: rockchip: Add CPU resets for RK3128
  ARM: dts: rockchip: Add SRAM node for RK3128
  ARM: dts: rockchip: Enable pwm fan for edgeble-neu2
  ARM: dts: rockchip: Add pwm11 node to rv1126
  ARM: dts: rockchip: Add pwm11m0 pins to rv1126
  ARM: dts: rockchip: Add pwm2 node to rv1126
  ARM: dts: rockchip: Add pwm2m0 pins to rv1126
  dt-bindings: pwm: rockchip: Document rv1126-pwm
