spi/pxa2xx: Restore private register bits.

2013-11-28T11:23:37Z

The Intel LPSS SPI private register bits have to be restored when system resume from S3 suspend. Signed-off-by: Chew, Chiau Ee Acked-by: Mika Westerberg Signed-off-by: Mark Brown

spi/qspi: Fix qspi remove path.

2013-11-24T14:15:11Z

There is a bug in qspi removal path, as a result of which qspi cannot be removed when used as a module. The patch solves the bug and qspi can be removed cleanly. The bugs fixed are: -pm_runtime used around register access. - pm_runtime_disable need to be done before removal. - spi_unregister_master need to be called to unregister the spi device. Tested on DRA7 board. Signed-off-by: Sourav Poddar Signed-off-by: Mark Brown

spi/qspi: cleanup pm_runtime error check.

clean up pm_runtime error check in accordance with rest of the check in the driver. Signed-off-by: Sourav Poddar Signed-off-by: Mark Brown

spi/qspi: set correct platform drvdata in ti_qspi_probe()

2013-11-24T14:15:10Z

The ti_qspi_remove() use the platform drvdata as a type of struct ti_qspi, we should pass correct platform drvdata to platform_set_drvdata() in ti_qspi_probe(). Signed-off-by: Wei Yongjun Signed-off-by: Mark Brown

spi/pxa2xx: add new ACPI IDs

2013-11-24T14:10:45Z

Newer Intel PCHs with LPSS have the same SPI controllers than Haswell but ACPI IDs are different. Add these IDs to the driver list. Signed-off-by: Mika Westerberg Signed-off-by: Mark Brown Cc: stable@vger.kernel.org

spi: core: invert success test in devm_spi_register_master

2013-11-22T00:07:29Z

devres_add() should be called when the action to be undone succeeded, not when it failed. Fix the inverted test in devm_spi_register_master() which was doing the opposite. The user-visible issue without this fix is: insmod spi-tegra114.ko Assume there's an MTD device on that SPI bus, which creates /dev/mtd0. rmmod spi-tegra114 Doesn't remove devices on the SPI bus. insmod spi-tegra114.ko Creates a duplicate SPI device which creates /dev/mtd1. hexdump -C /dev/mtd0 That's the old device, which uses an SPI bus hosted by a non-existent module, which causes the oops below.

Pull slave-dmaengine changes from Vinod Koul: "This brings for slave dmaengine: - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as dmaengine can only transfer and not verify validaty of dma transfers - Bunch of fixes across drivers: - cppi41 driver fixes from Daniel - 8 channel freescale dma engine support and updated bindings from Hongbo - msx-dma fixes and cleanup by Markus - DMAengine updates from Dan: - Bartlomiej and Dan finalized a rework of the dma address unmap implementation. - In the course of testing 1/ a collection of enhancements to dmatest fell out. Notably basic performance statistics, and fixed / enhanced test control through new module parameters 'run', 'wait', 'noverify', and 'verbose'.
