Subject: [RESEND PATCH v2 3/3] regulator: lp87565: Add 4-phase lp87561 regulator support
Date: Wed, 12 Jun 2019 20:16:20 +0530 [thread overview]

The LP8756x family has a single output 4-phase regulator
configuration. Add support for the same. The control
lies in the master buck which is buck0 for 4-phase
configuration. Enable/disable/voltage set happen via
buck0 registers.
