Its not only DTS entries, we are still missing the CPR APSS voltage regulator and APSS PLL clk driver.
I dont think they are scaling the cache at all, or its being done outside of Linux control as only the generic OPP DT frequency scaling is used.
Tsens does not work out of the box, they have modified the v2 a bit as it seems.
Their ethernet driver is using switchdev + the awfull SSDK for the PHY-s/switch.
I dont like that at all.
PHY-s are not hard as I already have a working QCA8075 PHY driver, QCA8081 for 2.5G is much simpler and it should not be hard and for 10G Aquantia ones are already mainline.
But the switch is still the same one from IPQ40xx with the same issues, but they now have multiple EDMA ethernet adapters modified to run at higher speeds.
MDIO controller is the same one as in IPQ40xx, I have upstreamed that and even Clause 45 support was merged into 5.10.
I will add clock handling to it as well as IPQ807x/IPQ60xx have a separate MDIO clocks.
No pending upstream patches for anything clk or networking related stuff.
