Subject: [PATCH] pinctrl: nomadik: decomission non-DT boot path
After the patches deleting the last board registering this
pin controller as a platform device has been deleted,
proceed to remove the non-DT boot patch and depend on
OF being available and the device to be coming up by
a DT node.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
---
This will be merged through ARM SoC with dependent
patches removing the dependence on platform data headers
etc.
