* dma: mv_xor: Remove multi-slot supportLior Amsalem2014-09-232-93/+32
| | | | | | | | | | Although the driver supported multiple-slot allocation, only one slot was ever allocated for each transaction. So, given we have no users of the multi-slot support, we can remove it and greatly simplify the code.

* dma: mv_xor: Simplify the DMA_MEMCPY operationLior Amsalem2014-09-231-65/+12
| | | | | | | | | | | | | A memory copy operation can be expressed as an XOR operation with one source. This commit removes code duplication in the driver by reusing the XOR operation for the MEMCPY. As an added benefit, we can now put MEMCPY and XOR descriptors on the same chain, which improves performance.

* spi/pxa2xx: Don't use slave_id of dma_slave_configMika Westerberg2014-09-184-36/+54
| | | | | | | | | | | | | | | | | That field has been deprecated in favour of getting the necessary information from ACPI/DT. However, we still need to deal systems that are PCI only (no ACPI to back up). In order to support such systems, we allow the DMA filter function and its corresponding parameter via pxa2xx_spi_master platform data. Then when the pxa2xx_spi_dma_setup() doesn't find the channel via ACPI, it falls back to use the given filter function.

| | | | | | | | | | | | | | | | | | | | | | | | SPI PXA2XX core layer has dependency on common clock framework to obtain information on host supported clock rate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On BayTrail platform DMA is not functional in the PCI mode, whereby it always failed and exit at the point when it tries to get a clock.

* | dmaengine: dw: introduce generic filter functionAndy Shevchenko2014-09-113-67/+40
| | | | | | | | | | | | | | | | | | | | | | | | The introduced filter function would be reused in the ACPI and DT cases since in those cases we have to apply mandatory data to the requested channel. Thus, patch moves platform driver to use it in that case. The function unlikely can't be used by users of the driver due to an implicit dependency to the dw_dmac_core module.

* | dmaengine: dw: apply both HS interfaces and remove slave_id usageAndy Shevchenko2014-09-113-35/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of one request line member let's use both source and destination ones. Usually we have no such hardware except Atmel MMC controller found on AVR32 platform (see arch/avr32/mach-at32ap/at32ap700x.c and drivers/mmc/host/atmel-mci.c). This patch removes slave_id usage since it'll be removed from the generic structure in later. This breaks the non-ACPI / non-DT cases for the users of the driver, i.e. SPI and HSUART. However, these cases mean only PCI enumerated devices for now, which is anyway broken (considering more than one DMA controller in the system) and this patch series is intended to fix that eventually. The ACPI and DT cases shall be aware of the channel direction when setting request lines, but this is a minor problem that would be addressed in future.

| | | | | | | | | | | | | | | | | | Constify the asus_quirks[] DMI table. There's no need to have it writeable during runtime. Signed-off-by: Mathias Krause <minipli@googlemail.com> Cc: Corentin Chary <corentin.chary@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
| * acer-wmi: Mark init data and code as suchMathias Krause2014-08-161-20/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | Quite a lot of code and data of acer-wmi.c is only ever used during initialization. Mark those accordingly -- and constify, where appropriate -- so the memory can be released afterwards. All in all those changes move ~10 kB of code and data to the .init sections, marking them for release after initialization has finished.
