2023-11-16power: reset: qnap-poweroff: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2014-10-20power: reset: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-03-04Power: Reset: Generalize qnap-poweroff to work on Synology devices.Andrew Lunn1-12/+37
The Synology NAS devices use a very similar mechanism to QNAP NAS devices to power off. Both send a single charactor command to a PIC, over the second serial port. However the baud rate and the command differ. Generalize the driver to support this.

2013-01-07power/reset: Add a new driver to turn QNAP board power offAndrew Lunn1-0/+116
The QNAP NAS boxes have a microcontroller attached to the SoCs second serial port. By sending it a simple command, it will turn the power for the board off. This driver registers a function for pm_power_off to send such a command. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
