   4 Subject: [PATCH] clk: qcom: apss-ipq-pll: use OF match data for Alpha PLL
   5  config
   6
   7 Convert the driver to use OF match data for providing the Alpha PLL config
   8 per compatible.
   9 This is required for IPQ8074 support since it uses a different Alpha PLL
  10 config.
  11
  12 While we are here rename "ipq_pll_config" to "ipq6018_pll_config" to make
  13 it clear that it is for IPQ6018 only.
