* drivers: Introduce dev_set_name()Andrey Smirnov2018-10-181-1/+1
| | | | | | | | Introduce dev_set_name() in order to hide implementation details of setting device's name so it'd be easier to change it. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* drivers: bus: Match against id_table firstAndrey Smirnov2015-12-071-3/+2
| | | | | | | | | | | | | | | | Matching against driver's name before looking throught its id_table can lead to a somewhat strange and unintuitive behaviour where a device whose driver's name matches one of the lines in id_table (which is not unheard of in Linux kernel) will be probed against said driver with 'id_table' field set to NULL which in turn will result in dev_get_drvdata erroring out with -ENODEV. This patch changes the behaviour such that device_match() only tries to match against driver's name only if id_table of that driver is not present.

* drivers/base: Mark (of|platform)_device_id data as constantUwe Kleine-König2015-04-171-2/+2
| | | | | | | | | | There should be no reason to ever change the data pointed to by id_table or of_compatible. So make this offical by adding some 'const's. In Linux the corresponding pointers are marked as const, too. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* i2c/spi: match of_modaliasesSascha Hauer2014-02-071-0/+37
| | | | | | | | i2c/spi devices in the devicetree often come with a "vendor,device" comaptible string. These do not match in barebox, so add a device_match_of_modalias function which does exactly that. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: Add missing includesSascha Hauer2013-11-081-0/+1
| | | | | | | | A lot of files rely on include/driver.h including include/of.h (and this including include/errno.h. include the files explicitly so we can eventually get rid of including of.h from driver.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* base: Transform "platform_match" into "device_match" and make this function ↵Alexander Shiyan2013-07-151-0/+24
| | | | | | | | | public This change will allow reuse this function for other buses. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bus: Make struct device a pointerSascha Hauer2013-03-141-3/+4
| | | | | | | | struct bus_type contains an embedded struct device_d which is quite a big structure. Dynamically allocate this instead to save the space in the binary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
