H A D | system.dts | 7cca9b8b Fri Aug 23 04:47:28 CDT 2019 Linus Walleij <linus.walleij@linaro.org> microblaze: Switch to standard restart handler
The microblaze uses the legacy APIs to dig out a GPIO pin defined in the root of the device tree to issue a hard reset of the platform.
Asserting a hard reset should be done using the standard DT-enabled and fully GPIO descriptor aware driver in drivers/power/reset/gpio-restart.c using the bindings from Documentation/devicetree/bindings/power/reset/gpio-restart.txt
To achieve this, first make sure microblaze makes use of the standard kernel restart path utilizing do_kernel_restart() from <linux/reboot.h>. Put in some grace time and an emergency print if the restart does not properly assert.
As this is basic platform functionality we patch the DTS file and defconfig in one go for a lockstep change.
