6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luca Weiss luca.weiss@fairphone.com
commit 3b0011059334a1cf554c2c1f67d7a7b822d8238a upstream.
As per dt-bindings the property is called vddio-supply, so use the correct name in the driver instead of iovdd. The datasheet also calls the supply 'VDDIO'.
