…binding
Raspberry Pi 5 booted with no ethernet and no USB. The boot log showed
the PCIe root complex that RP1 hangs off failing at probe:
brcm-pcie 1000120000.pcie: Unable to find MSI PCI address
brcm-pcie: probe of 1000120000.pcie failed with error -22
The firmware-provided device tree uses the upstreamed MIP MSI-X binding
("brcm,bcm2712-mip") which differs from the older downstream binding
("brcm,bcm2712-mip-intc") that these 6.1 drivers were written against:
- MIP compatible is "brcm,bcm2712-mip" (no "interrupt-controller"
property, only "msi-controller"), so of_irq_init()/IRQCHIP_DECLARE
never matches the node.
- The GIC SPI base/count come from the "msi-ranges" property instead
of brcm,msi-base-spi / brcm,msi-num-spis.
- The MSI doorbell address is the second reg region instead of the
brcm,msi-pci-addr property.
Adapt both drivers to accept either binding (keeping backward
compatibility with the in-tree device tree):
- irq-bcm2712-mip: parse msi-ranges and reg[1] as fallbacks, and
register a platform driver (IRQCHIP_PLATFORM_DRIVER) for
"brcm,bcm2712-mip" since the node is populated as a platform device
rather than picked up by of_irq_init().
- pcie-brcmstb: when brcm,msi-pci-addr is absent, take the MSI PCI
(doorbell) address from reg[1] and the MIP register base from reg[0],
reading the raw untranslated reg cells.

Enable SPI support for Raspberry Pi 5 (driven by the RP1 chip). This is needed specially for TPMs connected through the SPI bus. Signed-off-by: Renê de Souza Pinto <rene@renesp.com.br>
