Subject: [PATCH v5 2/5] clk: qcom: gcc: Add support for modem clocks in GCC
Date: Mon, 24 Feb 2020 16:08:20 +0530	[thread overview]
Message-ID: <1582540703-6328-3-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1582540703-6328-1-git-send-email-tdas@codeaurora.org>

Add the required modem clocks in global clock controller which are
required to bring the modem out of reset.
