change email address for Pali Rohár

2020-04-10T22:36:22Z

For security reasons I stopped using gmail account and kernel address is now up-to-date alias to my personal address. People periodically send me emails to address which they found in source code of drivers, so this change reflects state where people can contact me.

power: reset: sc27xx: Allow the SC27XX poweroff driver building into a module

2020-03-11T22:32:09Z

Change the config to 'tristate' and use module_platform_driver() to allow the SC27XX poweroff driver building into a module, as well as adding some mudule information. Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel

power: reset: sc27xx: Change to use cpu_down()

2020-03-11T22:32:09Z

To allow the SC27XX driver can be built as a module, and the freeze_secondary_cpus() symbol is not exported, thus we can change to use the exported cpu_down() API to shut down other cpus to avoid racing, which is same as the freeze_secondary_cpus().

power: reset: sc27xx: Power off the external subsystems' connection

2020-03-11T22:32:09Z

When powering off the whole system, we should power off some external subsystems' connection firstly, otherwise some external subsystems will hold some power and result in powering down abnormally. Signed-off-by: Sherry Zong Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel

power: twl4030: Use scnprintf() for avoiding potential buffer overflow

2020-03-11T22:20:32Z

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf(). Signed-off-by: Takashi Iwai Signed-off-by: Sebastian Reichel

power: supply: bq27xxx_battery: Silence deferred-probe error

2020-03-11T22:08:07Z

The driver fails to probe with -EPROBE_DEFER if battery's power supply (charger driver) isn't ready yet and this results in a bit noisy error message in KMSG during kernel's boot up. Let's silence the harmless error message. Signed-off-by: Dmitry Osipenko Reviewed-by: Andrew F. Davis Reviewed-by: Pali Rohár Signed-off-by: Sebastian Reichel

power: reset: at91-reset: handle nrst async for sam9x60
