I don't think you should select 'PINCTRL and PINMUX' here, as long as the code builds without them. Arnd

I use it to show something sensible in /proc/cpuinfo, to report whether the soc is a 4760 or 4761 and the silicon revision. If the proper way to deal with this has so much boilerplate as you say, I think I'll drop it altogether. I'd like to print the info somewhere in the bootlog anyway. btw this could well be one of the accesses requiring the io mapping above. >> + uart0@c0000 { >> + compatible = "brcm,bcm4760-pl011", "arm,pl011", "arm,primecell"; >> + reg = <0xc0000 0x1000>; >> + interrupt-parent = <&vic0>; >> + interrupts = <14>; >> + }; >> + >> + uart1@c1000 { >> + compatible = "brcm,bcm4760-pl011", "arm,pl011", "arm,primecell"; >> + reg = <0xc1000 0x1000>; >> + interrupt-parent = <&vic0>; >> + interrupts = <15>; >> + }; >> + >> + uart2@b2000 { >> + compatible = "brcm,bcm4760-pl011", "arm,pl011", "arm,primecell"; >> + reg = <0xb2000 0x1000>; >> + interrupt-parent = <&vic0>; >> + interrupts = <16>; >> + }; >> + }; > >Please change the names here to say "serial" rather than "uartX".

If it's just for informational purposes, soc_device_register() sounds like the correct place to put that information, you can register a couple of strings there that get put into sysfs at a known location for the SoC, and keeps the cpuinfo for the actual CPU core.

Shouldn't the mach-bcm subdir be included always and let then Makefile therein sort what to build? As I side note, I think this CONFIG_ARCH_BCM option is misnamed, shouldn't be something like CONFIG_ARCH_BCM281XX? It looks about this ARMv7 family only. Thanks, Domenico

This showed to be also the only user of the early io mapping, which is now gone. I'll respin the patchset as soon as you suggest what to do with the clock-frequency of the system timer. BRs, Domenico
