Subject: [PATCH] clk: qcom: apss-ipq-pll: use OF match data for Alpha PLL
|
||
|
|
config
|
||
|
|
|
||
|
|
Convert the driver to use OF match data for providing the Alpha PLL config
|
||
|
|
per compatible.
|
||
|
|
This is required for IPQ8074 support since it uses a different Alpha PLL
|
||
|
|
config.
|
||
|
|
|
||
|
|
While we are here rename "ipq_pll_config" to "ipq6018_pll_config" to make
|
||
|
|
it clear that it is for IPQ6018 only.
