[PATCH v2 0/6] GPIO reset support

[Anup Patel]

This series adds generic GPIO reset (poweroff/restart) support which is
required by SiFive platforms.

These patches can be found in gpio_reset_v2 branch at:
https://github.com/avpatel/opensbi.git

Changes since v2:
 - Re-designed the GPIO framework to probe GPIO drivers on demand
   and avoid touching generic OpenSBI library.

Anup Patel (4):
  lib: utils/fdt: Add fdt_parse_phandle_with_args() API
  lib: utils/gpio: Add generic GPIO configuration library
  lib: utils/gpio: Add simple FDT based GPIO framework
  lib: utils/fdt: Disable GPIO restart and poweroff nodes in
    fdt_fixups()

Green Wan (2):
  lib: utils/gpio: Add minimal SiFive GPIO driver
  lib: utils/reset: Add generic GPIO reset driver
