Subject: [PATCH v3 05/12] phy: qcom-ufs: Skip obtaining rx/tx_iface_clk for msm8996 based phy
Date: Sun, 30 Oct 2016 01:52:07 +0530	[thread overview]
Message-ID: <1477772534-14170-6-git-send-email-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <1477772534-14170-1-git-send-email-vivek.gautam@codeaurora.org>

The tx_iface_clk and rx_iface_clk no longer exist with UFS Phy
present on msm8996. So skip obtaining these clocks using
compatible match.

Signed-off-by: Vivek Gautam <vivek.gautam@codeaurora.org>

New patch in v3 of this cleanup series.
Comes in place of the following patch in v2 -
 phy: qcom-ufs: remove failure when rx/tx_iface_clk are absent
