[PATCH V2 RESEND 0/4] ARM: bcm2835: DT improvements

[PATCH V2 RESEND 0/4] ARM: bcm2835: DT improvements

[Stefan Wahren]

This patch series contains DT improvements for the Raspberry Pi.

Patch 1,2: Add missing vendor prefix and root compatible properties
Patch 3,4: Use constants for pin function instead of error-prone numbers

Changes in V2:
- add all currently known Raspberry Pi boards to binding documentation 
  as suggested by Stephen Warren

Stefan Wahren (4):
  dt-bindings: Add vendor prefix for Raspberry Pi
  dt-bindings: Add root properties for Raspberry Pi
  ARM: bcm2835: Add header file for pinctrl constants
  ARM: bcm2835: Use pinctrl header

[PATCH V2 RESEND 1/4] dt-bindings: Add vendor prefix for Raspberry Pi

[Stefan Wahren]

Since the prefix is already in use, we need to add it in the
vendor list.

It doesn't look like it. I was under the impression that Lee was 
applying bcm2835 patches now, hence why I simply gave my reviewed-by tag 
rather than doing anything else. Lee, can you comment?

All I can do is apologise.  My filters are working correct, but my

Who do you intend to apply this? For the DT binding parts:

I assume Lee Jones will take this through the Tegra tree, to avoid any 
potential conflicts with other changes to these files in that tree.

I do still want to double-check with the Pi Foundation's downstream tree 
what compatible values they use. If they already have board-specific 
values, and they're sane, it'd be nice to align with those. 
Unfortunately, I haven't got around to that yet:-(
