Subject[RFC PATCH 16/34] msm: clock-pcom: Expose pc_clk_reset
Date
From: Stephen Boyd <sboyd@codeaurora.org>

The 7x30 clock driver needs to perform clock resets and the only
way that is possible is through proc_comm. Expose the reset
functionality as a new function callable from the 7x30 clock
driver.
