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

93ac5a552c ARM: platform data to use the FSMC NAND with the U300
Just as it says, if this is merged along with the other patch, the
driver supports the U300 NAND flash interface.

3af8a8dad0 ARM: 6297/1: move U300 timer to dynamic clock lookup
This moves the U300 timer code to look up its clock rate from the
clock framework as is apropriate and also switches it over to use
the generic code for *calc_mult_shift() on clock source and clock
event.

b7276b236d ARM: 6296/1: clock U300 intcon and timer properly
This removes the quirks to clock the U300 VIC and timer by custom
hooks and moves the control out to the clock framework where it
belongs. This is possible now that clocks are available early.

379aae5d6c ARM: 6295/1: fix U300 apb_pclk split
This fixes a regression due to the new apb_pclk stuff in the U300
platform, makes it run by splitting the apb clock off the single
UART clocks. For the MMCI and PL022 clocks we don't split them:
these are actually hardwired to the same clock terminal and will
thus simply have a double reference count and will be referenced
twice.

We also move clock registration to .init_irq() so they are
available early enough for probing to be successful and remove the
earlier quirk to clock primecells during PrimeCell registration.

3126c7bc41 ARM: AMBA: Add pclk definition for platforms using primecells
Add a dummy clk definition for the APB pclk signal on all platforms
using the AMBA bus infrastructure.  This ensures that these platforms
continue to work when the core amba bus code controls the APB pclk.

cd71f8f48e ARM: 5958/1: ARM: U300: fix inverted clk round rate
The clk_round_rate() functions in the U300 clocking will always
select the lowest clocking frequency due to inverted rounding
comparisons. Fix this.

0a0300dc8c ARM: Consolidate clks_register() and similar
Most machine classes want some way to register a block of clk_lookup
structures, and most do it by implementing a clks_register() type
function which walks an array, or by open-coding a loop.

Consolidate all this into clkdev_add_table().

4ebfc3dba5 [ARM] 5581/1: U300 clock updates
This adds a few default locks to the clocks (the clocks were used
before the locks were initialized by code), then renames the clocks
a bit to fit with the latest driver names (some changed during
review). Lastly it moves the initialization of the clock debugfs
entry to module_init() initcall level since the debugfs isn't up
in core_initcall().
