The PL011 driver in this downstream kernel tree supports an extra compatible string - arm,pl011-axi - for use by RP1. This registers as a platform driver, not an AMBA driver, and has the advantage of responding to dynamic Device Tree changes such as loading one of the "uart<n>" overlays. Change all of the downstream Raspberry Pi dts files to use the new compatible string. At the same time, remove the override of the periphid as the upstream code now has the correct value.

So uart10 is on the bcm2712 SoC itself and not on the RP1 chip so I don't think the change to uart10 is correct @pelwell but it should just be for the RP1 uarts. |

Although prompted by RP1, I think the new compatible string is equally applicable to 2712 and 2711. There is no AMBA bus on any of these chips, and we'd rather have the benefit of responding to dynamic DT changes that you get from using a platform driver. |

You should leave the original compatibles so there's fall back, eg this breaks with an upstream kernel. |
