Hi all,
After merging the arm-soc tree, today's linux-next build (arm
multi_v7_defconfig) produced these warnings:
arch/arm/boot/dts/bcm953012hr.dts:57.3-33: Warning (reg_format): /nand-controller@18028000/nand@0/partition@0:reg: property has invalid length (8 bytes) (#address-cells == 2, #size-cells == 1)

I don't know what caused this now.

Thank you for the reminder, I have now reverted commit 90103611d573 ("ARM: dts:
BCM5301X: Fix DTC warning for NAND node"), which caused the problem.
The patch was meant to fix a different warning
Warning (avoid_unnecessary_addr_size):
/nand-controller@18028000/nand@0: unnecessary
#address-cells/#size-cells without "ranges" or child "reg" property
but I don't see that here, so I don't know if it was actually required.
Arınç, Rafał, Florian: if the original problem comes back now, please
send a follow-up patch
that addresses all the warnings.

I was using an unusual method to compile DTs which produced the warning:
$ cpp -nostdinc -I include -I arch -undef -x assembler-with-cpp
arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts processed.dts &&

Now that I know how to properly compile the dt files, I don't see any
issues before the fix DTC commit or after the revert:

Hi all,
After merging the arm-soc tree, today's linux-next build (arm
multi_v7_defconfig) produced these warnings:
arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): /soc/apb@d4000000/spi@d4037000: incorrect #address-cells for SPI bus
also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3
arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): /soc/apb@d4000000/spi@d4037000: incorrect #size-cells for SPI bus
also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3
arch/arm/boot/dts/mmp2-olpc-xo-1-75.dtb: Warning (spi_bus_reg): Failed prerequisite 'spi_bus_bridge'
I have no idea what causes these warnings.

These warnings now appear in builds of Linus' tree.
