* devfs: Drop dev_lseek_default()Andrey Smirnov2019-01-291-1/+0
| | | | | | | | | | | | | | | | | | | | | Only the following cdevs do not declare an .lseek() operation: - Console devices in common/console.c - Firmware framework in common/firmware.c - JTAG driver in drivers/misc/jtag.c - UBI in drivers/mtd/ubi/barebox.c Of those four, first two are marked DEVFS_IS_CHARACTER_DEV and implement only .write() operation and the last two don't implement anything but .ioctl(). While there's probably no meaningful way to use lseek() against any of those devices, there doesn't seem to be any harm in allowing it either. Change devfs_lseek() to ignore absense of .lseek() callback and drop dev_lseek_default() and all references to it in the codebase.

* 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>
* rename file_operations -> cdev_operationsSascha Hauer2018-04-061-1/+1
| | | | | | | | Linux also has struct file_operations which are something different. Rename our file_operations to cdev_operations which better matches what we have. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ratp: implement generic command supportAleksander Morgado2018-03-011-0/+5
| | | | | | | | | | | | | | | | | | | The RATP implementation now allows executing generic commands with a binary interface: binary requests are received and binary responses are returned. Each command can define its own RATP request contents (e.g. to specify command-specific options) as well as its own RATP response contents (if any data is to be returned). Each command is associated with a pair of numeric unique request and response IDs, and for easy reference these IDs are maintained in the common ratp_bb header. Modules may override generic implemented commands or include their own new ones (as long as the numeric IDs introduced are unique).

* sandbox: use 'poweroff' command for exitAntony Pavlov2018-01-253-18/+18
| | | | | | | | The 'poweroff' command is more appropriate for exit barebox than 'reset'. Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* sandbox: fix registering multiple consolesAleksander Morgado2017-06-011-3/+2
| | | | | | | | | | | | | | | | | | Consoles need to be registered with the "console" device name so that they are probed by the correct driver. The barebox_register_console() was already forcing this as it was overwriting the name that was being passed as argument, but it was failing to provide a unique id for each new console, so the underlying register_device() would just return an error when wanting to re-register a device with device name "console" and id 0. We remove the unused name parameter from barebox_register_console() as it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id, so that a new unique device id is given to each newly registered console device.

* treewide: Use of_property_write_string() where appropriateSascha Hauer2017-03-301-4/+2

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-272-0/+18
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

* Set model and hostname at boardlevelSascha Hauer2013-08-161-0/+3
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
