| * ARM: S3C2410: Add armclk for cpufreq supportBen Dooks2009-07-30
| | | | | | | | | | | | | | | | | | Add armclk for use with the cpufreq support and anything else that may want it. This clock is just a direct descendant of fclk. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | Add a sysdev S3C2410A sysdev to allow the differentiation of the S3C2410A from the S3C2410. This is needed for the CPUFREQ code to enable the extra features and update cpu specific information. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| * ARM: S3C: Update CPU register mapping practices.Ben Dooks2009-07-30
| | | | | | | | | | | | | | | | | | | | | | | | Currently map-base.h defines the main virtual address mappings made for all the support S3C SoC series, but does not then define any base for per-cpu mappings to be made from. Add S3C_ADDR_CPU() macro to define an virtual address as an offset from the last of the core mappings. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | Add ARCH_HAS_CPUFREQ so that each machine config can select it if they have CPUFREQ driver support.

| * ARM: S3C: Add ADC synchronous read call.Ben Dooks2009-07-18
| | | | | | | | | | | | | | | | | | To add HWMON support, we need a synchronous read() call that blocks until completion. Add the client that is being service to the select and convert callbacks to make the code easier. Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the hwmon device name to something more generic as this should be functional for both the s3c24xx and s3c64xx archs. Since it has yet to have a driver, it is pretty safe to change as there are no extant users. Also add the necessary entry in devs.h which seems to have been missed out at somepoint.

* | S3C64XX: Fix ARMCLK configurationMark Brown2009-07-29
| | | | | | | | | | | | | | | | | | | | | | The value of armclk_mask needs to be inverted for use as a mask on the register value when updating ARM_RATIO. This is critical for cpufreq support, without it attempts to scale the frequency of the core trash pretty much the entire clock tree.

* | S3C64XX: Fix get_rate() for ARMCLKMark Brown2009-07-29
| | | | | | | | | | | | | | | | | | If the requested clock is faster than the parent clock then the parent clock is the closest we can get to the request so we need to return that instead of the requested clock.

* | S3C24XX: GPIO: Fix pin range check in s3c_gpiolib_getchipLars-Peter Clausen2009-07-29
| | | | | | | | | | | | | | | | | | | | In the s3c_gpiolib_getchip implementation for s3c24xx the check whether a pin is in the gpio banks range is reversed. Thus the function returns NULL for valid pins and the gpio chip if its not valid. As a result gpio states are not saved/restored properly during suspend/resume.

* | mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt2009-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

| | * ARM: add support for the EET board, based on the i.MX31 pcm037 moduleGuennadi Liakhovetski2009-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "EET" variant of the pcm037 board has an OLED display, using a S6E63D6 display controller on the first SPI interface, using GPIO57 as a chip-select for it. S6E63D6 is initialised in the boot-loader, so we only have to take care of the LCD. EET also adds several buttons and LEDs on GPIOs. This patch adds a "pcm037_variant=" kernel command line parameter to specify at boot-time which board the kernel is running on, default is "pcm970", specify "eet" for the EET board.
