[PATCH 0/4] Pass reset reason to Linux via FDT

[A. Sverdlin]

From: Alexander Sverdlin <alexander.sverdlin at siemens.com>

Make get_reset_reason() available on TI K3 AM62x and AM64x SoCs a model
for further SoC/platform-specific implementations.

Introduce new CONFIG_RESET_REASON_FDT option and optionally populate reset
reason in FDT passed to Linux under /chosen/reset-reason with a string
returned by get_reset_reason().

The above paves a way to pass reset reason information to Linux user space
in a platform-agnostic way.

Alexander Sverdlin (4):
  arm: mach-k3: Allow for calling get_reset_reason() twice
  nxp: imx9: rename get_reset_reason() -> print_reset_reason()
  common: Make TI K3 get_reset_reason() a weak global
  fdt: Optionally populate /chosen/reset-reason
