From f2fd74c45c769127c2291ff2709c09ff8b168393 Mon Sep 17 00:00:00 2001 From: Subbaraman Narayanamurthy Date: Fri, 12 Oct 2018 17:44:19 -0700 Subject: [PATCH] platform: msm: Add snapshot of QPNP_REVID driver QPNP_REVID driver provides the PMIC revision, type and subtype of every PMIC device to the peripheral drivers on request. This is used by peripheral drivers to configure the hardware properly. This is taken as a snapshot from msm-4.19 kernel commit 9a702c565e5a ("Use 'GPL-2.0-only' as the SPDX-License-Identifier tag").
