In the move to the upstream bcm2712.dts, the A76 PMU was omitted from the required downstream additions. Link: raspberrypi#6507 Signed-off-by: Phil Elwell <[email protected]>
Following the merging of [1], it is safe to re-enable DMA to UART0 without fear of losing data. Seen while looking at raspberrypi#6507. [1] dmaengine: dw-axi-dmac: Allow client-chosen width Signed-off-by: Phil Elwell <[email protected]>

gpio-direct mode is a modification of the brcmstb GPIO driver that makes it play nicely with the userspace pinctrl utility. The mode forces the drive to read its state from the hardware each time, rather than relying on cached state. Doing so slightly reduces performance, but this is not a heavily used code path.

As noticed in #6507, the arm-pmu declaration is missing from rpi-6.12.y. Likewise, the re-enabling of DMA to RP1's UART0.
