Subject: [PATCH] [RESEND] ARM: bcm47094: add missing #cells for mdio-bus-mux
Date: Mon, 22 Jul 2019 16:55:52 +0200
Message-ID: <20190722145618.1155492-1-arnd@arndb.de> (raw)

The mdio-bus-mux has no #address-cells/#size-cells property,
which causes a few dtc warnings:

arch/arm/boot/dts/bcm47094-linksys-panamera.dts:129.4-18: Warning (reg_format): /mdio-bus-mux/mdio@200:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
arch/arm/boot/dts/bcm47094-linksys-panamera.dtb: Warning (pci_device_bus_num): Failed prerequisite 'reg_format'
arch/arm/boot/dts/bcm47094-linksys-panamera.dtb: Warning (i2c_bus_reg): Failed prerequisite 'reg_format'
arch/arm/boot/dts/bcm47094-linksys-panamera.dtb: Warning (spi_bus_reg): Failed prerequisite 'reg_format'
arch/arm/boot/dts/bcm47094-linksys-panamera.dts:128.22-132.5: Warning (avoid_default_addr_size): /mdio-bus-mux/mdio@200: Relying on default #address-cells value
arch/arm/boot/dts/bcm47094-linksys-panamera.dts:128.22-132.5: Warning (avoid_default_addr_size): /mdio-bus-mux/mdio@200: Relying on default #size-cells value

Add the normal cell numbers.

As Florian is apparently on vacation at the moment, let's merge this
as a bugfix through arm-soc directly to get closer to clean allmodconfig
build.
