2016-05-06spi: pic32-sqi: Remove pic32_sqi_setup and pic32_sqi_cleanupAxel Lin1-41/+0
Current code does not use ctldata at all, so remove spi_set_ctldata call. spi_setup() will set spi->bits_per_word = 8 if it was not set, so remove !spi->max_speed_hz checking. The spi core allows absent of spi->max_speed_hz setting, if it was not set spi_setup() assigns spi->master->max_speed_hz to it. spi core allows spi->max_speed_hz > spi->master->max_speed_hz, in this case spi core will limit the transfer speed to ensure xfer->speed_hz won't greater than spi->master->max_speed_hz so remove checking if spi->max_speed_hz is higher than spi->master->max_speed_hz.

2016-04-26spi: pxa2xx: Do not detect number of enabled chip selects on Intel SPTJarkko Nikula1-1/+1

Detection in pxa2xx_spi_probe() sets master->num_chipselect to 0 leading to -EINVAL from spi_register_master() where chip select count is validated. Fix this by not using SPI capabilities register on Sunrisepoint. They don't have more than one chip select so use the default value 1 instead of detection.

2016-04-13dmaengine: dw: rename masters to reflect actual topologyAndy Shevchenko1-4/+4
The source and destination masters are reflecting buses or their layers to where the different devices can be connected. The patch changes the master names to reflect which one is related to which independently on the transfer direction. The outcome of the change is that the memory data width is now always limited by a data width of the master which is dedicated to communicate to memory. The patch will not break anything since all current users have the same data width for all masters. Though it would be nice to revisit avr32 platforms to check what is the actual hardware topology in use there. It seems that it has one bus and two masters on it as stated by Table 8-2, that's why everything works independently on the master in use. The purpose of the sequential patch is to fix the driver for configuration of more than one bus. The change is done in the assumption that src_master and dst_master are reflecting a connection to the memory and peripheral correspondently on avr32 and otherwise on the rest.

We clamp frame_len_words to a maximum of 4096, but do not actually limit the number of words written or read through the DATA registers or the length added to spi_message::actual_length. This results in silent data corruption for commands longer than this maximum. Recalculate the length of each transfer, taking frame_len_words into account. Use this length in qspi_{read,write}_msg(), and to increment spi_message::actual_length.

Each transfer can specify 8, 16 or 32 bits per word independently of the default for the device being addressed. However, currently we calculate the number of words in the frame assuming that the word size is the device default. If multiple transfers in the same message have differing bits_per_word, we bitwise-or the different values in the WLEN register field. Fix both of these. Also rename 'frame_length' to 'frame_len_words' to make clear that it's not a byte count like spi_message::frame_length.

The actual transfer length for DMA RX can be less than xfer->len in the specific condition and the last words will be filled after the DMA completion, but the commit doesn't consider it and the dmaengine is started with rx_sg mapped by spi core.
