Subject: [PATCH v2 02/17] phy: qcom-qmp: Adapt to clk_bulk_* APIs
Date: Wed, 27 Sep 2017 14:28:58 +0530	[thread overview]
Message-ID: <1506502753-27408-3-git-send-email-mgautam@codeaurora.org> (raw)
In-Reply-To: <1506502753-27408-1-git-send-email-mgautam@codeaurora.org>

From: Vivek Gautam <vivek.gautam@codeaurora.org>

Move from using array of clocks to clk_bulk_* APIs that
are available now.
