Subject: ARM: imx: use MXxy_IO_P2V macros to setup static mappings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes less code rely on the virtual constants.

To further simplify code and reduce the needed boilerplate when
defining the static mappings a new helper macro is defined in
mach/hardware.h.

Subject: ARM: 6483/1: arm & sh: factorised duplicated clkdev.c

factorise some generic infrastructure to assist looking up struct clks
for the ARM & SH architecture.

as the code is identical at 99%

put the arch specific code for allocation as example in asm/clkdev.h
