* 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>
* param: make parameter functions more consistentSascha Hauer2017-04-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* amba: check if on remove callbackAlexander Aring2015-10-271-1/+2
| | | | | | | | | | | Currently we get a null pointer dereference when booting linux on RPi which use "uart-pl011" driver. This driver doesn't implement a remove driver callback. This patch adds a check before calling the remove callback if the driver which use the amba bus implement such functionality.

* Introduce ARM AMBA busJean-Christophe PLAGNIOL-VILLARD2012-09-111-0/+210
This will allow to detect the amba device and use the right driver for it at runtime. The code is base on linux 3.5. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
