[05/11] clk: qcom: ipq8074: add remaining PLL’s

Commit Message

Abhishek Sahu Sept. 26, 2017, 12:23 p.m. UTC

- GPLL2, GPLL4 and GPLL6 are general PLL clocks and parent
  for all core peripherals.
- UBI PLL is mainly used by NSS (Network Switching System).
  IPQ8074 has 2 instances of NSS UBI cores and UBI PLL will
  be used to control the core frequency.
- NSS Crypto PLL is mainly used by NSS Crypto Engine which
  supports the multiple cryptographic algorithm used in
  Ethernet.
