[PATCH 0/8] ARM: i.MX7: add serial download reboot mode

[Ahmad Fatoum]

BootROM can be forced into USB recovery on i.MX7 just like on the
i.MX8M, with the difference that reset is a bit more involved,
because warm resets via watchdogs are broken on this SoC.

We do a bit of cleanup and then tackle that via a syscon-reboot
device describing the Cortex-A7 CPU0 reset.

Ahmad Fatoum (8):
  restart: make restart.h header self-contained
  restart: do restart-priority OF parsing in restart_handler_register
  restart: add reset -w for warm bootrom reset
  watchdog: imxwd: don't register broken imxwd-warm for i.MX7
  watchdog: imxwd: set imxwd-warm as reboot mode default handler
  Documentations: devicetree: bindings: document watchdog-priority
  ARM: i.MX7: describe USB serial download boot mode
  ARM: stm32mp: mark iwdg2 with barebox,restart-warm-bootrom
