Subject: [PATCH v2 3/3] regulator: lp87565: Add 4-phase lp87561 regulator support
Date: Thu, 16 May 2019 10:02:18 +0530	[thread overview]
Message-ID: <20190516043218.8222-4-j-keerthy@ti.com> (raw)
In-Reply-To: <20190516043218.8222-1-j-keerthy@ti.com>

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.

Changes in v2:

  * Changed if/else block to switch statement.
