Subject[PATCH 05/11] clk: qcom: ipq8074: add remaining PLL’s
Date
- 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.
