git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (101 commits) crypto: ux500: use dmaengine_submit API crypto: ux500: use dmaengine_prep_slave_sg API crypto: ux500: use dmaengine_device_control API crypto: ux500/crypt: add missing __iomem qualifiers crypto: ux500/hash: add missing static qualifiers crypto: ux500/hash: use readl on iomem addresses dmaengine: ste_dma40: Declare memcpy config as static ARM: ux500: Remove mop500_snowball_ethernet_clock_enable() ARM: ux500: Correct the EN_3v3 regulator's on/off GPIO ARM: ux500: Provide a AB8500 GPIO Device Tree node gpio: rcar: fix gpio_rcar_of_table gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections gpio-rcar: Reference core gpio documentation in the DT bindings clk: exynos5250: Add enum entries for divider clock of i2s1 and i2s2 ARM: dts: Update Samsung I2S documentation ARM: dts: add clock provider information for i2s controllers in Exynos5250 ARM: dts: add Exynos audio subsystem clock controller node clk: samsung: register audio subsystem clocks using common clock framework ARM: dts: use #include for all device trees for Samsung pinctrl: s3c24xx: use correct header for chained_irq functions ...

2013-05-23ARM: ux500: Remove DMA address look-up tableLee Jones1-80/+0
DMA addresses are now passed as part of the dmaengine API by invoking dmaengine_slave_config(). So there's no requirement for the DMA40 driver to look them up in a table provided by platform data. This method does not fit in well using Device Tree either.

2013-05-23ARM: ux500: Pass remnant platform data though to DMA40 driverLee Jones1-1/+1
Ironically, in order to remove lots of the auxdata assignments, we have to add just one more. A lot of them require DMA information to be passed into clients for DMA channel allocation, but we now have this capability in Device Tree. However, the DMA40 driver still relies on a reverse table look-up to obtain DMA addresses. Until all of the clients are converted, over to the new API, we're stuck with this. Also, now the DMA40 has been DT:ed, there's no requirement to register it using traditional methods, so let's remove it.

2013-05-23dmaengine: ste_dma40: Calculate number of logical channels from physical onesLee Jones1-1/+0
This change will cost ~25KB of memory, but it's worth the trade-off, as it removes a great deal of overhead. It means that instead of only allocating memory for the logical channels in use, it does so for all available ones, which is 32 per physical channel. However, this now means we can remove some platform data and we don't have to worry about adding vendor specific variables to Device Tree.

2013-05-23dmaengine: ste_dma40: Amalgamate DMA source and destination channel numbersLee Jones1-60/+60
Devices which utilise DMA use the same device numbers for transmitting and receiving. In this patch we encode the source and destination information into one single attribute. We can subsequently exploit the direction attribute to see which of the transfer directions are being described. This also lessens the burden on platform data.

2013-05-23dmaengine: ste_dma40: Move default memcpy configs into the driverLee Jones1-28/+0
There are only two default memcpy configurations used for the DMA40 driver; one for physical memcpy and one for logical memcpy. Instead of invariably passing the same configurations though platform data, we're moving them into the driver instead.

2013-05-23dmaengine: ste_dma40: Assign memcpy channels in the driverLee Jones1-12/+0
The channels reserved for memcpy are the same for all currently supported platforms. With this in mind, we can ease the platform data passing requirement by moving these assignments out from platform code and place them directly into the driver.

There is some impact outside the ux500 machine, but most of it is dealt with in earlier patches. Contains portions of a clean-up patch from Arnd Bergmann.

This untangles the final bits of the prcmu code from the platform code: * The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c because they are only of local significance. * u8500_thsens_device goes into the prcmu, because it uses a PRCMU IRQ that the platform does not see. * IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data because the PRCMU does not see it.

2013-02-12mfd: db8500-prcmu: update resource passingLinus Walleij1-0/+44
When trying to get rid of the cross-includes of <mach/id.h> from different drivers, so we can localize ASIC/CPU detection to the mach-ux500 folder, we run into the way the PRCMU handles base addresses and firmware detection. This patch updates the firmware version detection to pass the required information as platform data instead of relying on cpu_is_* macros. Now the PRCMU base address, the secondary TCDM area, the TCPM area and the IRQ are passed as resources instead of being grabbed from <mach/*> files. Incidentally this also removes part of the reliance on <mach/irqs.h>. Further it updates the firmware version detection, since the location of the firmware ID bytes in the designated memory are is now passed from the platform data instead. There is no reason not to include the nice split-off of a struct to hold the firmware information and a separate function to populate it. The patch actually rids the need to use the external db8500_prcmu_early_init call at all, but I'm keepin back that removal as I don't want the patch to be too big.
