[PATCH v4 0/2] make kurobox-pro be able to shutdown after device-tree migration

[Roger Shimizu <rogershimizu@gmail.com>]

Dear Kernel Maintainers,

Kurobox-Pro (and variants) need more commands sending to UART1 to shutdown.
So here I make this patch series to let current qnap-poweroff implementation
be able to handle such case.

Here I give 3 patches, for 3 different kernel subsystems respectivelay:
  - Patch 1/3: System reset/shutdown driver
  - Patch 2/3: Open firmware and flattened device tree bindings
  - Patch 3/3: ARM/Marvell Dove/MV78xx0/Orion SOC support

Ryan Tandy, the issue reporter, and I have already tested those changes on
Linkstation/KuroBoxPro devices, and confirmed it's working well.

Merry Xmax and look forward to your feedback!

Changes:
  v0 => v1:
  - Update 0003 to split kuroboxpro related code into kuroboxpro-common.c
  v1 => v2:
  - Split off linkstation/kuroboxpro related code to linkstation-reset.c
    Because linkstation before kuroboxpro also need this driver to power
    off properly. It's more proper to call it linkstation driver.
  v2 => v3:
  - Split off devicetree bindings doc into a separate patch.
  - Add device-tree patch to make Linkstation LS-GL and KuroBox Pro to
    use the newly created linkstation-reset driver.
  - Remove the unused one-byte command sending case in linkstation-reset
    driver.
  v3 => v4:
  - Reduce the global singleton variables by moving to structure, which makes
    the driver easy to support reboot function in the future.  Thanks to
    Florian Fainelli.
  - Simplify the power_off function registration. Thanks to Florian Fainelli.
  - Drop DT binding doc.
