Subject: [PATCH 0/3] of: functions to count number of elements and convert regulators

In a different thread [0] Mark Rutland suggested that drivers should not
repeatedly open-code the counting of array elements in a property as well
as handling the format and endianes of the DTB, as these should be limited
to the of_ helper functions.

Therefore the first patch introduces a set of helper functions for counting
the number of u8,...,u64 elements in a property.

The second and third patch convert the two regulator drivers that use this
pattern to instead use both of_property_count_u32_elemens as well as
of_property_read_u32_index.

gpio-regulator change tested on a s3c2416-based device, ti-abb-regulator
compile-tested only.

Heiko Stuebner (3):
  of: add functions to count number of elements in a property
  regulator: gpio-regulator: do not open-code counting and access of dt array elements
  regulator: ti-abb-regulator: do not open-code counting and access of dt array elements
