| |/ | | | | | | | | | | | | | | | | | | | | Since we are using regmap framework's internal locks, so the lock_arg for dspi_regmap_config is redundant here. This patch just remove it, and then the dspi_regmap_config could be const type. Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* / spi: fsl-dspi: Fix CTAR selectionAlexander Stein2014-11-041-2/+2
|/ | | | | | | | | | | | There are only 4 CTAR registers (CTAR0 - CTAR3) so we can only use the lower 2 bits of the chip select to select a CTAR register. SPI_PUSHR_CTAS used the lower 3 bits which would result in wrong bit values if the chip selects 4/5 are used. For those chip selects SPI_CTAR even calculated offsets of non-existing registers.

|/ | | | | | | | | | | | Sort all the include headers alphabetically for the freescale spi drivers. If the inlcude headers sorted out of order, maybe the best logical choice is to append new ones after the exist ones, while this may create a lot of potential for duplicates and conflicts for each diffenent changes will add new headers in the same location.

| | * spi/fsl-dspi: Convert to use regmap and add big-endian supportChao Fu2014-02-161-27/+53
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Freescale DSPI module will have two endianess in different platform, but ARM is little endian. So when DSPI in big endian, core in little endian, readl and writel can not adjust R/W register in this condition. This patch will remove general readl/writel, and import regmap mechanism. Data endian will be transfered in regmap APIs. Documents: dspi add bool "big-endian" in dts node if DSPI module work in big endian.

| * | spi: bitbang: Let spi_bitbang_start() take a reference to masterAxel Lin2013-09-171-1/+1
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many drivers that use bitbang library have a leak on probe error paths. This is because once a spi_master_get() call succeeds, we need an additional spi_master_put() call to free the memory. Fix this issue by moving the code taking a reference to master to spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on success. With this change, the caller is responsible for calling spi_bitbang_stop() to decrement the reference and spi_master_put() as counterpart of spi_alloc_master() to prevent a memory leak. So now we have below patten for drivers using bitbang library: probe: spi_alloc_master -> Init reference count to 1 spi_bitbang_start -> Increment reference count remove: spi_bitbang_stop -> Decrement reference count spi_master_put -> Decrement reference count (reference count reaches 0) Fixup all users accordingly.

* spi:Add Freescale DSPI driver for Vybrid VF610 platformChao Fu2013-08-221-0/+557
The serial peripheral interface (SPI) module implemented on Freescale Vybrid platform provides a synchronous serial bus for communication between Vybrid and the external peripheral device. The SPI supports full-duplex, three-wire synchronous transfer, has TX/RX FIFO with depth of four entries. This driver is the SPI master mode driver and has been tested on Vybrid VF610TWR board.
