Subject: [PATCH 4.2.y-ckt 177/206] clk: qcom: msm8916: Fix crypto clock flags

4.2.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Andy Gross <andy.gross@...aro.org>

commit 2a0974aa1a0b40a92387ea03dbfeacfbc9ba182c upstream.

This patch adds the CLK_SET_RATE_PARENT flag for the crypto core and
ahb blocks.  Without this flag, clk_set_rate can fail for certain
frequency requests.
