Subject: [PATCH] clk: qcom: apss-ipq-pll: add support for IPQ8074
|
||
|
|
|
||
|
|
Add support for IPQ8074 since it uses the same PLL setup, however it uses
|
||
|
|
slightly different Alpha PLL config.
|
||
|
|
|
||
|
|
Alpha PLL config was obtained by dumping PLL registers from a running
|
||
|
|
device.
