Subject: clk: qcom: Fix mmcc-8974's PLL configurations
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9e0126ef80c2c33f6ce8aeca9035e8baa6e7d3d0;p=karo-tx-linux.git

clk: qcom: Fix mmcc-8974's PLL configurations

commit 437ae6a1b8f2eedebfbf0f6572e19ca5c58a3f71 upstream.

We forgot to add the status bit for the PLLs and we were using
the wrong register and masks for configuration, leading to
unexpected PLL configurations. Fix this.

Fixes: d8b212014e69 (clk: qcom: Add support for MSM8974's multimedia clock controller (MMCC))
