From 744ef9b091b8b4f6c6246c8e70dd817175bde8bc Mon Sep 17 00:00:00 2001 From: Adam Ward Date: Mon, 30 Nov 2020 16:59:05 +0000 Subject: regulator: Update DA9121 dt-bindings Update bindings for the Dialog Semiconductor DA9121 voltage regulator to add device variants. Because several variants have multiple regulators, and to regard potential to add GPIO support in future, the 'regulators' sub-node is added, following the precedent set by other multi-regulator devices, including the DA9211 family. This breaks compatibility with the original submission by Vincent Whitchurch - but as this is still in for-next, the alignment could be made before upstreaming occurs.
