From d64102e00a8e3aebda8427df3b2c36bf4639928f Mon Sep 17 00:00:00 2001 From: Yanase Yuki Date: Sat, 18 Apr 2020 14:49:13 +0900 Subject: [PATCH] ipq806x: add support for Qualcomm IPQ8062 SoC 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.
