* eeprom: at25: check return value of devfs_createUwe Kleine-König2016-05-311-1/+4
| | | | | | | | Also only emit the message that the device was probed when it actually was. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* eeprom/at25: parse partitions from device treeHarald Welte2016-02-181-0/+1
| | | | | | | | | | | | Unlike at24 (I2C), the at25 (spi) EEPROM driver doesn't check if the device tree node contains partition definitions. This means that one for example cannot have bootstate partitions on an at25 EEPROM, while it works on an at24 EEPROM. This patch adds device tree based partition support to the at25 driver.

* remove redundant NULL check on freeLucas Stach2014-02-101-2/+1
| | | | | | | | free() already checks the pointer to be non NULL. No need to do it again. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* SPI: Put SPI devices on their own busSascha Hauer2012-09-141-1/+1
| | | | | | | | | 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.
