Subject: [PATCH V9 1/6] dt-bindings: mfd: pm8008: Add reset-gpios

Add reset-gpios property for pm8008.

Signed-off-by: Satya Priya <quic_c_skakit@...cinc.com>
---
Changes in V7:
 - Removed the intermediate regulators node and added ldos
   directly under mfd node.

Changes in V8:
 - Change the compatible as per driver, remove interrupts from required
   properties, add reset-gpios and move regulators to separate binding.

Changes in V9:
 - Undo the changes from V8 and only add reset-gpios. Leave interrupts
   as required properties and do not change compatible.
