2010-11-26ARM: 6483/1: arm & sh: factorised duplicated clkdev.cJean-Christop PLAGNIOL-VILLARD1-1/+1
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 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-10-25ARM: platform data to use the FSMC NAND with the U300Linus Walleij1-3/+3
Just as it says, if this is merged along with the other patch, the driver supports the U300 NAND flash interface. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-08-10ARM: 6297/1: move U300 timer to dynamic clock lookupLinus Walleij1-1/+5
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.

2010-08-10ARM: 6296/1: clock U300 intcon and timer properlyLinus Walleij1-19/+0
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.

2010-08-10ARM: 6295/1: fix U300 apb_pclk splitLinus Walleij1-63/+53
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.

2010-07-22ARM: AMBA: Add pclk definition for platforms using primecellsRussell King1-0/+6
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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-02-24ARM: 5958/1: ARM: U300: fix inverted clk round rateLinus Walleij1-12/+12
The clk_round_rate() functions in the U300 clocking will always select the lowest clocking frequency due to inverted rounding comparisons. Fix this. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-02-12ARM: Consolidate clks_register() and similarRussell King1-4/+1
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().

2009-07-02[ARM] 5581/1: U300 clock updatesLinus Walleij1-41/+80
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().

2009-04-28[ARM] 5474/1: U300 clocking frameworkLinus Walleij1-0/+1487
