* 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>

* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-6/+9

* firmware: socfpga: Add parameter "programmed" to fpgamgr driverTrent Piepho2015-11-111-11/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This boolean parameter tells you if the FPGA is programmed or not. It can be accessed from the shell as "$fpga.programmed". One could use this to not program the FPGA if it's already programmed. There is an annoying limitation of the way barebox puts parameters into the shell env: it requires they have no periods in the device name. It uses the first period to divide the variable name into a device and parameter name, which doesn't work correctly if the device name has a period in it. Since the names of any devices created from the OF device tree have a period in them, this is a problem. So what I did here was create a new device. Its parent will be the OF device for the fpgamgr and it will in turn be the parent of the firmware cdev. Previously the cdev's parent was the OF device. This device won't have period in the name and the parameter is attached to it. Even without the period limitation, doing this gives a nicer name "fpga.programmed" instead of "ff706000.fpgamgr.programmed". The fpgamgr code had a pointer to the OF device in its private state. I changed this to be a struct for the new "fpga" device, which is then used in all the places the former pointer was (nothing but dev_dbg, etc. calls).
