[PATCH 0/3] OMAP hwspinlock DT updates

[Suman Anna]

Hi,

This series updates the existing OMAP hwspinlock DT nodes to have a
#hwlock-cells property as suggested by Mark Rutland [1], and adds the
hwspinlock nodes for two other newer SoCs - DRA7xx and AM43xx.

Posting the series separately from the driver DT adapation changes [2]
to avoid maintainer confusion.

[PATCH 1/3] ARM: dts: OMAP: Add #hwlock-cells property to hwspinlock nodes

[Suman Anna]

Add a new generic property "#hwlock-cells" to the hwspinlock
DT nodes on OMAP4, OMAP5 and AM33xx. This common property allows
different platform implementations to define the args specifier
length. OMAP implementations will always use a value of 1.
