[PATCH v2 0/3] diverse at91 related fixes

[Sam Ravnborg]

This is a rework of the two patches sent earlier + an extra patch.
With these patches my AT91SAM9263EK board boots barebox.

clk: fix clk_get error handling
- changed based on feedback from Uwe, test for -ENOENT

gpiolib: fix: do not access oftree on non-OFDEVICE boards
- rebased on top of Alexenaders original fix

And a third patch that just adds a missing static (found while browsing code)
