[PATCH v2 0/2] pinctrl: single: fixes for davinci

[Axel Haslam]

After recent pinctl patches we see a warning when booting davinci
due to a bad memory allocation:

This series fixes this error.

Changes form v1 -> v2
* Add an error message, and correct also other places where the
issue is seen

* Add patch to parse for bits instead of pins

Axel Haslam (2):
  pinctrl: single: check for any error when getting rows
  pinctrl: single: search for the bits property when parsing bits
