Subject: [PATCH v3 1/1] clk: qcom: smd: Add support for SDM660 rpm clocks
Date:   Mon, 22 Jun 2020 11:02:52 +0200
Message-Id: <20200622090252.36568-1-konradybcio@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add rpm smd clocks, PMIC and bus clocks which are required on
SDM630/660 (and APQ variants) for clients to vote on.

changes since v2:
- separate from SDM630 enablement series
- fix indentation in Docs
- sort compatible strings alphabetically
- drop an accidental newline
