This patch introduces support for the tcc platform by creating an arch/arm/plat-tcc and arch/arm/mach-tcc8k directories and adding basic include files plus Kconfig and Makefile.

These look like a duplication (n << 2) of the standard 8250 definitions in serial_reg.h

Yep. Meanwhile I've got confirmation from Telechips that this is actually supposed to be a 8250-compatible thing. I will use that driver in the future, so for the moment, I threw away all UART-related stuff. Thanks for that hint!

etc. Please use the already established definitions from linux/serial_reg.h

I don't think that's true; what you're saying is that the CPU will never execute any instructions after the __raw_writel - what if the write is buffered and doesn't take effect immediately - are you happy for the CPU to start executing data?

Grmbl... The meaning of unreachable() has changed. OK, I replaced it with a while(1);

New patch series will follow.

Thanks,
Hans

Is this left over from the old clk_set_parent() implementation - with the handling of refcounting in the main clk_set_parent(), this refcounting seems unnecessary (and seems buggy.)

Right. All refcounting is already done in plat-tcc/clock.c, so this __set_parent() became obsolete. I removed it completely, because the initial parent setting is already done elsewhere.
