This commit adds support for Qualcomm IPQ8062 SoC.
IPQ8062 is a lower clock variant of IPQ8064.
CPU and NSS clocks:
- CPU: 384 MHz - 1 GHz
- NSS: 110 MHz - 550 MHz
opp and l2 clock values are taken from WG2600HP3 GPL source code [1].
Due to a lack of devices, I didn't test the following features.
- SATA
- NAND flash memory controller
- SD
- USB
- GSBI2, GSBI7
- PCIE2
- GMAC0, GMAC3
Works properly:
- GSBI4 UART
- GSBI5 SPI
- GMAC1, GMAC2
- PCIE0, PCIE1
- MDIO0
Does not work properly:
- CPU SPC
- This can cause a system hang. Same as IPQ8065.
See 2336c2dbb1
