power: reset: reboot-mode: Make include file global

2017-06-08T16:18:19+00:00

Move the reboot-mode.h include file into include/linux to allow drivers outside drivers/power/reset to implement reboot-mode. Signed-off-by: Bjorn Andersson Signed-off-by: Sebastian Reichel

power: reset: Default POWER_RESET_BRCMSTB to BMIPS_GENERIC

2017-06-08T11:05:30+00:00

On Broadcom MIPS STB platforms, BMIPS_GENERIC is the Kconfig symbol that is used, make this reboot driver default to that value to make sure we can reboot a system properly. Signed-off-by: Florian Fainelli Signed-off-by: Sebastian Reichel

power: reset: Allow selecting POWER_RESET_BRCMSTB on ARM64

2017-06-08T11:05:29+00:00

Since commit 37eb56dc79a8 ("arm64: Add Broadcom Set Top Box Kconfig entry point") we have ARCH_BRCMSTB also visible on ARM64 platform, yet this reboot driver was not selectable, so fix that. Signed-off-by: Florian Fainelli Signed-off-by: Sebastian Reichel

power: reset: Add a driver for the Gemini poweroff

2017-04-13T23:41:33+00:00

The Gemini (SL3516) SoC has a special power controller block that only deal with shutting down the system. If you do not register a driver and activate the block, the power button on the systems utilizing this SoC will do an uncontrolled power cut, which is why it is important to have a special poweroff driver. The most basic functionality is to just shut down the system by writing a special bit in the control register after the system has reached pm_poweroff. It also handles the poweroff from a button or other sources: When the poweroff button is pressed, or a signal is sent to poweroff from an infrared remote control, or when the RTC fires a special alarm (!) the system emits an interrupt. At this point, Linux must acknowledge the interrupt and proceed to do an orderly shutdown of the system. After adding this driver, pressing the poweroff button gives this dmesg: root@gemini:/ root@gemini:/ gemini-poweroff 4b000000.power-controller: poweroff button pressed calling shutdown scripts.. setting /dev/rtc0 from system time unmounting file systems... umount: tmpfs busy - remounted read-only umount: can't unmount /: Invalid argument The system is going down NOW!

power: reset: syscon-poweroff: add a mask property

2017-04-13T23:41:33+00:00

Make the syscon-poweroff driver accept value and mask instead of just value. Prior to this patch, the property name for the value was 'mask'. If only the mask property is defined on a node, maintain compatibility by using it as the value. Signed-off-by: Guy Shapiro Acked-by: Rob Herring Signed-off-by: Sebastian Reichel

power: reset: at91-reset: remove leftover platform_device_id

2017-01-18T16:05:46+00:00

commit eacd8d09db7f ("power/reset: at91-reset: remove useless at91_reset_platform_probe()") removed non DT probe support but forgot to remove the now useless id_table. Do that now. Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel

power: reset: at91-reset: add samx7 support

2017-01-18T16:05:38+00:00

Add samx7 support. It is lacking a few bits and needs a new reset function. Signed-off-by: Szemző András Signed-off-by: Alexandre Belloni Signed-off-by: Sebastian Reichel
