[RFC PATCH 16/34] msm: clock-pcom: Expose pc_clk_reset
From: David Brown <hidden>
Date: 2011-11-02 18:42:03
Also in:
linux-arm-msm, lkml
Subsystem:
arm port, the rest · Maintainers:
Russell King, Linus Torvalds
From: Stephen Boyd <redacted> 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.
