85922e54a3 arm: tcc8k: Choose PLL settings conforming to board layout
The evaluation board is driven with 1.2V core voltage, so system clock
must not exceed 192 MHz, bus clock must not exceed 110 MHz. Choose
appropriate values and set DTCMWAIT accordingly. Adapt UART setting to
avoid console log interruption and wait for the specified locking time
of 300us to pass.

6b46340a18 ARM: tcc8k: update clock source registration
In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.

6d803ba736 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

6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]
