2013-07-14arm: delete __cpuinit/__CPUINIT usage from all ARM usersPaul Gortmaker1-2/+2
The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

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.

2013-05-27ARM: ux500: Provide supplies for AUX1, AUX2 and AUX3Lee Jones1-0/+3
This patch fixes a bug introduced in the v3.10 merge window. The AB8500 External Regulator driver has recently landed upstream, which registers each of the 3 external regulators located on the AB8500. If these regulators are marked as 'always on', there is a potential for power-loss. If they're not and are seemingly unused the Regulator subsystem will attempt to disable them to save power. This causes an issue for AUX1, AUX2 and AUX3 as they obtain their power from EXT3. So we're specifying that here to prevent EXT3 from being powered down.

2013-05-27ARM: ux500: Create a new of_dev_auxdata structure for u8540 enablementLee Jones1-2/+17
If we attempt to use the existing u8500 of_dev_auxdata struct to boot the u8540, we fail to obtain a console, due to a lack of DMA support on the platform. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-05-27ARM: ux500: regulators: Remove misleading commentLee Jones1-1/+0
This patch removes a comment which explains that the ab8505 platform uses the same initialisation settings as the ab8500. Well when this changed and the ab8505 started using its own set of initialisation values, someone forgot to remove it.

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
For several reasons, the mmc protocol layer expects devices being non-removable to use MMC_CAP_NONREMOVABLE, so then we adapt to this expectation. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-05-27ARM: ux500: Enable support for RPMB and Reliable Write for eMMCUlf Hansson1-4/+8
By adding MMC_CAP_CMD23 for the eMMC devices, we can support RPMB and Reliable Write. Additionally it will mean CMD12 will not be sent to end a successful data transfer. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
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). Thus it is pointless of specifing these mask and why we do remove them. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-05-23ARM: ux500: Register Cryp and Hash platform drivers on SnowballLee Jones1-0/+2

2013-05-23ARM: ux500: Stop passing Cryp DMA channel config information though pdataLee Jones1-8/+0
DMA channel configuration information should be setup in the driver. The Ux500 Cryp driver now does this, so there's no need to send it though here too. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-05-23ARM: ux500: Remove unnecessary attributes from DMA channel request pdataLee Jones1-8/+0
DMA data width and packet size information is only required at channel configuration time. Any information passed from platform data is passed directly to the DMA40 driver to use during channel allocation, but these pieces of information are subsequently ignored by the driver, so we may as well remove them.

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: Stop passing UART's platform data for Device Tree bootsLee Jones1-3/+3
It was required to pass DMA channel configuration information to the UART driver before the new DMA API was in place. Now that it is, and is fully compatible with Device Tree we can stop doing that.

2013-05-23ARM: ux500: Pass remnant platform data though to DMA40 driverLee Jones3-11/+5
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.
