2014-10-13spi/dw: use dmaengine_slave_config() APIVinod Koul1-4/+2
The drivers should use dmaengine_slave_config() API instead of accessing the device_control which will be deprecated soon Signed-off-by: Vinod Koul <[email protected]> Signed-off-by: Mark Brown <[email protected]>
2014-09-24spi: dw: fix style of code in few placesAndy Shevchenko1-4/+3
Make comments be surrounded by spaces and move part of code to one line where it suits 80 characters. There is no functional changes. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]>
2014-09-24spi: dw: introduce support of loopback modeAndy Shevchenko1-1/+4
For testing purposes it's good to have a loopback mode enabled. The patch adds necessary bits for that. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]>
2014-09-24spi: dw-mid: terminate ongoing transfers at exitAndy Shevchenko1-0/+4
Do full clean up at exit, means terminate all ongoing DMA transfers. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]> Cc: [email protected]
2014-09-24spi: dw-mid: respect 8 bit modeAndy Shevchenko1-2/+2
In case of 8 bit mode and DMA usage we end up with every second byte written as 0. We have to respect bits_per_word settings what this patch actually does. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]> Cc: [email protected]
2014-09-13spi: dw: don't use mrst prefix anymoreAndy Shevchenko1-17/+15
Since driver is used on other platforms and debugfs stuff would be useful there as well let's substitute mrst_ by dw_ where it suits. Additionally let's use SPI master device name when print registers dump. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]>

2014-09-13spi: dw-mid: check that DMA was inited before exitAndy Shevchenko1-0/+2
If the driver was compiled with DMA support, but DMA channels weren't acquired by some reason, mid_spi_dma_exit() will crash the kernel. Fixes: 7063c0d942a1 (spi/dw_spi: add DMA support) Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Mark Brown <[email protected]>

2014-08-16toshiba_acpi: Add extra check to backlight codeAzael Avalos1-4/+17
Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support. This patch changes the set_lcd_brightness function, checking the returned values for values greater than zero to avoid registering a broken backlight interface.
