* SPI: Put SPI devices on their own busSascha Hauer2012-09-141-0/+7
| | | | | | | | | This patch adds a SPI bus on which the SPI devices and drivers register. This makes it cleaner as SPI devices won't accidently end up probed by a platform_device driver.

* spi: indicate in the docs that per-transfer bpw setting is not supportedPaul Fertser2011-09-291-1/+2
| | | | | | | | Currently it's not implemented by any driver so add a note to the documentation. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* nor: Add SPI flash driverFranck Jullien2011-08-241-0/+30
| | | | | | | | | This patch adds the m25p80 driver. It has been ported from Linux. MTD code has been removed. It has been tested with a m25p40 chip and the Altera SPI master driver. Signed-off-by: Franck Jullien <franck.jullien@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* spi: add bits_per_word to proxy structureFranck Jullien2011-07-061-0/+1
| | | | | | | | | | | | | During the creation of a new spi device, we need to have the possiblility to give the bits_per_word value to master->setup. As a matter of fact, spi master could check the spi device bits_per_word and compare this value against its capabilities.

* eeprom: add at25 eeprom driverHubert Feurstein2011-06-211-0/+22

* spi: add more spi transfer functionsHubert Feurstein2011-06-211-0/+74
| | | | | | | | | | | | | This commit adds the following spi transfer functions: - spi_write - spi_read - spi_write_then_read - spi_w8r8 The code has been ported from the linux kernel. Signed-off-by: Hubert Feurstein <h.feurstein@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* spi: add platform_data pointer to spi_board_infoHubert Feurstein2011-06-211-2/+2
| | | | | | | | | In the spi layer this pointer will be assigned to the platform_data pointer of the new spi device, thus it can be accessed in the drivers 'probe' handler. Signed-off-by: Hubert Feurstein <h.feurstein@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
