spi: qup: Remove chip select function

2014-06-22T10:48:09Z

This patch removes the chip select function. Chip select should instead be supported using GPIOs, defining the DT entry "cs-gpios", and letting the SPI core assert/deassert the chip select as it sees fit. The chip select control inside the controller is buggy. It is supposed to automatically assert the chip select based on the activity in the controller, but it is buggy and doesn't work at all. So instead we elect to use GPIOs. Signed-off-by: Andy Gross Signed-off-by: Mark Brown

spi: qup: Fix order of spi_register_master

2014-06-21T10:11:54Z

This patch moves the devm_spi_register_master below the initialization of the runtime_pm. If done in the wrong order, the spi_register_master fails if any probed slave devices issue SPI transactions. Signed-off-by: Andy Gross Acked-by: Ivan T. Ivanov Signed-off-by: Mark Brown

spi/pxa2xx: fix incorrect SW mode chipselect setting for BayTrail LPSS SPI

2014-06-17T14:45:52Z

It was observed that after module removal followed by insertion, the SW mode chipselect is not properly set. Thus causing transfer failure due to incorrect CS toggling. Signed-off-by: Chew, Chiau Ee Acked-by: Mika Westerberg Signed-off-by: Mark Brown

spi/pxa2xx: change default supported DMA burst size to 1

2014-06-06T09:52:46Z

This is to fix the SPI DMA transfer failure for speed less than 1M. If using current DMA burst size setting (16), the Rx data bytes are invalid due to each data byte is multiplied according to the burst size setting. Let's said supposedly we shall receive the following 18 bytes of data: 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 Instead, the data bytes received consist of "16 bytes of '01' + 2 bytes of '02'" : 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 02 02 Signed-off-by: Chew, Chiau Ee Acked-by: Mika Westerberg Signed-off-by: Mark Brown
