2012-11-20dma: mv_xor: remove the pool_size from platform_dataThomas Petazzoni2-9/+7
The pool_size is always PAGE_SIZE, and since it is a software configuration paramter (and not a hardware description parameter), we cannot make it part of the Device Tree binding, so we'd better remove it from the platform_data as well.

2012-11-20dma: mv_xor: remove hw_id field from platform_dataThomas Petazzoni1-3/+3
There is no need for the platform_data to give this ID, it is simply the channel number, so we can compute it inside the driver when registering the channels. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: remove useless backpointer from mv_xor_chan to mv_xor_deviceThomas Petazzoni2-2/+0
The backpointer from mv_xor_chan to mv_xor_device is now useless, get rid of it. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: rename mv_xor_private to mv_xor_deviceThomas Petazzoni2-35/+35
Now that mv_xor_device is no longer used to designate the per-channel DMA devices, use it know to designate the XOR engine themselves (currently composed of two XOR channels). So, now we have the nice organization where: - mv_xor_device represents each XOR engine in the system - mv_xor_chan represents each XOR channel of a given XOR engine Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: merge mv_xor_device and mv_xor_chanThomas Petazzoni2-55/+34
Even though the DMA engine infrastructure has support for multiple channels per device, the mv_xor driver registers one DMA engine device for each channel, because the mv_xor channels inside the same XOR engine have different capabilities, and the DMA engine infrastructure only allows to express capabilities at the DMA engine device level. The mv_xor driver has therefore been registering one DMA engine device and one DMA engine channel for each XOR channel since its introduction in the kernel. However, it kept two separate internal structures, mv_xor_device and mv_xor_channel, which didn't make a lot of sense since there was a 1:1 mapping between those structures. This patch gets rid of this duplication, and merges everything into the mv_xor_chan structure. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: use mv_xor_chan pointers as arguments to self-test functionsThomas Petazzoni1-11/+6
In preparation for the removal of the mv_xor_device structure, we directly pass mv_xor_chan pointers to the self-test functions included in the driver. These functions were anyway selecting the first (and only channel) available in each DMA device, so the behaviour is unchanged. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: in mv_xor_device, rename 'common' to 'dmadev'Thomas Petazzoni2-8/+8
The mv_xor_device structure embeds a 'struct dma_device', which is named 'common', a not very meaningful name. Rename it to 'dmadev', which will help avoid confusions later as we merge the mv_xor_device and mv_xor_chan structures together. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2012-11-20dma: mv_xor: introduce a mv_chan_to_devp() helperThomas Petazzoni1-29/+32
In many place, we need to get the 'struct device *' pointer from a 'struct mv_chan *', so we add a helper that makes this a bit easier. It will also help reducing the change noise in further patches. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: simplify dma_sync_single_for_cpu() callsThomas Petazzoni1-6/+2
In mv_xor_memcpy_self_test() and mv_xor_xor_self_test(), all DMA functions are called by passing dma_chan->device->dev as the 'device *', except the calls to dma_sync_single_for_cpu() which uselessly goes through mv_chan->device->pdev->dev. Simplify this by using dma_chan->device->dev direclty in dma_sync_single_for_cpu() calls. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

'struct mv_xor_shared_platform_data' used to be the platform_data structure for the 'mv_xor_shared', but this driver is going to be renamed simply 'mv_xor', so also rename its platform_data structure accordingly. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: rename mv_xor_platform_data to mv_xor_channel_dataThomas Petazzoni1-1/+1
mv_xor_platform_data used to be the platform_data structure associated to the 'mv_xor' driver. This driver no longer exists, and this data structure really contains the properties of each XOR channel part of a given XOR engine. Therefore 'struct mv_xor_channel_data' is a more appropriate name.

2012-11-20dma: mv_xor: remove sub-driver 'mv_xor'Thomas Petazzoni1-48/+1
Now that XOR channels are directly registered by the main 'mv_xor_shared' device ->probe() function and all users of the 'mv_xor' device have been removed, we can get rid of the latter. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: allow channels to be registered directly from the main deviceThomas Petazzoni2-3/+50
Extend the XOR engine driver (currently called "mv_xor_shared") so that XOR channels can be passed in the platform_data structure, and be registered from there. This will allow the users of the driver to be converted to the single platform_driver variant of the mv_xor driver. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2012-11-20dma: mv_xor: split initialization/cleanup of XOR channelsThomas Petazzoni1-27/+48
Instead of doing the initialization/cleanup of the XOR channels directly in the ->probe() and ->remove() hooks, we create separate utility functions mv_xor_channel_add() and mv_xor_channel_remove(). This will allow to easily introduce in a future patch a different way of registering XOR channels: instead of having one platform_device per channel, we'll trigger the registration of all XOR channels of a given XOR engine directly from the XOR engine ->probe() function.

2012-11-20dma: mv_xor: do not use pool_size from platform_data within the driverThomas Petazzoni2-6/+5
The driver currently pokes into the platform_data structure during its normal operation to get the pool_size value. Poking into the platform_data structure is not nice when moving to the Device Tree, so this commit adds a new pool_size field in the mv_xor_device structure, which gets initialized at ->probe() time. The driver then uses this field instead of the platform_data. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2012-11-15ioat: Do not enable DCA if tag map is invalidAlexander Duyck1-0/+23
I have encountered several systems that have an invalid tag map. This invalid tag map results in only two tags being generated 0x1F which is usually applied to the first core in a Hyper-threaded pair and 0x00 which is applied to the second core in a Hyper-threaded pair. The net result of all this is that DCA causes significant cache thrash because the 0x1F tag will send traffic to the second socket, which the 0x00 tag will not DCA tag the frame resulting in no benefit. For now the best solution from the driver's perspective is to just disable DCA if the tag map is invalid. The correct solution for this would be to have the BIOS on affected systems updated so that the correct tags are generated for a given APIC ID.

This code will be eventually in drivers, and for the code in the drivers we don't want to have any cpu_is_omap usage. Those macros should be private to arch/arm/mach-omap1 and arch/arm/mach-omap2. To fix this, let's move the define for dma_omap2plus() to dma-omap.h, and use the existing dma_attr passed in the platform_data as the revision registers are what they are.

2012-10-25drivers/dma/dw_dmac: make driver's endianness configurableHein Tibosch2-5/+24
The dw_dmac driver was originally developed for avr32 to be used with the Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to the device's i/o memory was done with the little-endian readl/writel functions(1) This broke the driver for the avr32 platform, because it needs big (native) endian accessors. This patch makes the endianness configurable using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32 I submitted this patch before(2) but then waited for Andy to finish other changes to the same module(3).

2012-10-15ARM: OMAP: Trivial driver changes to remove include plat/cpu.hTony Lindgren1-2/+7
Drivers should not use cpu_is_omap or cpu_class_is_omap macros, they should be private to the platform init code. And we'll be removing plat/cpu.h and only have a private soc.h for the arch/arm/*omap* code. This patch is intended as preparation for the core omap changes and removes the need to include plat/cpu.h from several drivers. This is needed for the ARM common zImage support. These changes are OK to do because: - omap-rng.c does not need plat/cpu.h - omap-aes.c and omap-sham.c get the proper platform_data passed to them so they don't need extra checks in the driver - omap-dma.c and omap-pcm.c can test the arch locally as omap1 and omap2 cannot be compiled together because of conflicting compiler flags Cc: Deepak Saxena <dsaxena@plexity.net> Cc: Matt Mackall <mpm@selenic.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: David S.

Partly because of additional API support and partly because of constantly developed ASoC and ARM stuff. Some highlights: - Introduced the helper function and documentation for exposing the channel map via control API, as discussed in Plumbers; most of PCI drivers are covered, will follow more drivers later - Most of drivers have been replaced with the new PM callbacks (if the bus is supported) - HD-audio controller got the support of runtime PM and the support of D3 clock-stop. Also changing the power_save option in sysfs kicks off immediately to enable / disable the power-save mode. - Another significant code change in HD-audio is the rewrite of firmware loading code. Other than that, most of changes in HD-audio are continued cleanups and standardization for the generic auto parser and bug fixes (HBR, device-specific fixups), in addition to the support of channel-map API. - Addition of ASoC bindings for the compressed API, used by the mid-x86 drivers. - Lots of cleanups and API refreshes for ASoC codec drivers and DaVinci. - Conversion of OMAP to dmaengine. - New machine driver for Wolfson Microelectronics Bells. - New CODEC driver for Wolfson Microelectronics WM0010. - Enhancements to the ux500 and wm2000 drivers - A new driver for DA9055 and the support for regulator bypass mode."

2012-10-04dma: tegra: fix interrupt name issue with apb dma.Laxman Dewangan1-3/+3
When watching the interrupts through /proc/interrupts, the name of the interrupts are blank or garbage. The reason is the pointer passed for devname during irq registration is stack and so it get changed after dma registration completes. Allocate the pointer as part of dma channel and pass this pointer as the devname for irq registration to avoid change of name.

2012-10-01Merge tag 'multiplatform' of ↵Linus Torvalds6-7/+7
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

Pull ARM soc general cleanups from Olof Johansson: "This is a large branch that contains a handful of different cleanups: - Fixing up the I/O space remapping on PCI on ARM. This is a series from Rob Herring that restructures how all pci devices allocate I/O space, and it's part of the work to allow multiplatform kernels. - A number of cleanup series for OMAP, moving and removing some headers, sparse irq rework and in general preparation for multiplatform. - Final removal of all non-DT boards for Tegra, it is now device-tree-only! - Removal of a stale platform, nxp4008. It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel. We have not been able to find anyone interested in keeping it around in the kernel. - Removal of the legacy dmaengine driver on tegra + A handful of other things that I haven't described above."
