* ARM: ux500: Add placeholder for clk_set_parentOla Lilja2012-02-291-0/+7
| | | | | | | | Calling clk_set_parent (e.g. from Ux500 ASoC-driver) generates build-errors. Signed-off-by: Ola Lilja <ola.o.lilja@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: ux500: fix the smp_twd clock calculationLinus Walleij2011-12-191-2/+2
| | | | | | | | | | The clock for the smp_twd block is not equal to the CPU frequency, actually it is divided by two, so fix this, and set the initial frequency to half of 1GHz which is the most common case.

* ARM: ux500: remove support for early silicon revisionsLinus Walleij2011-12-191-154/+49
| | | | | | | | | | | The DB8500 ED (Early Drop) and V1 are only available inside of ST-Ericsson or partners, we have actively replaced and scrapped these prototypes. All Nova products on the open market (such as the Snowball board) are based on V2 and later ASIC variants. So let us focus on supporting the silicon that will be used and delete this to get a clear overview. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* | ARM: 6145/1: ux500 MTU clockrate correctionLinus Walleij2010-05-271-6/+98
|/ | | | | | | | | | | | | | | | | | This adjusts the clockrate for the MTU timer. On the different UX500 variants this rate is different. The platform can also have been set up at hardware initialization, bootloader or early init for different clock speeds. To have the clock framework available early so the timers can use them, the clock initialization for Nomadik and ux500 is moved to IRQ init time. A custom per-clock callback is added to handle special cases like this. This solves a user-visible bug: without this patch the current UX500 platforms will not be synchronized to wall-clock time and the platform will drift in time.

* ARM: Consolidate clks_register() and similarRussell King2010-02-121-4/+1
