2013-07-02Merge tag 'drivers-for-linus' of ↵Linus Torvalds1-40/+16
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 ...

2013-05-27ARM: ux500: Enable support for UHS-I SD-cardsUlf Hansson1-1/+3
By setting the host capabilities MMC_CAP_UHS_SDR12|25 for the SD card device we enable support for UHS cards. The supported mode is SDR12 and SDR25. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-05-27ARM: ux500: Set eMMC and WLAN card slot as non-removableUlf Hansson1-1/+4

2013-05-27ARM: ux500: Don't set plf ocr mask for SD/MMC deviceUlf Hansson1-2/+0
The mmci host driver overrides platform ocr mask when a vmmc regulator can be used. This is the case for sdi0(SD-card) and for sdi4(eMMC).

DMA configuration data is now allocated in the MMCI driver, so these are just ignored. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-05-23dmaengine: ste_dma40: Amalgamate DMA source and destination channel numbersLee Jones1-16/+8
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.

2012-02-13ARM: ux500: pass parent pointer to each platform deviceLee Jones1-15/+16
This patch provides a means for any device within ux500 platform code to allocate its own parent. This is particularly prudent with the introduction of /sys/devices/socX, as a device can now proclaim to be integral part of an SoC, rather than a more generic platform device.

2012-01-20ARM: 7219/1: mmc: mmci: Change vdd_handler to a generic ios_handlerUlf Hansson1-13/+8
The purpose of the vdd_handler does not make sense. We remove it and use a generic approach instead. A new ios_handler is added, the purpose of which e.g. can be to control GPIO pins to a levelshifter. Previously the vdd_handler was also used for making additional changes to the power register bits. This option is superfluous and is therefore removed. Adaptaptions from the old vdd_handler to the new ios_handler is done for mach-ux500 board, which was the only one using the vdd_handler. This patch is based upon a patch from Sebastian Rasmussen.

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.

The DB8500v2 and DB5500 has a fifth version of the "PL023" and PL180 blocks. However the ASIC engineers have forgot to bump the revision in the PrimeCell peripheral ID registers.
