We try to use DM in U-Boot proper as much as possible, but using DM in
SPL is currently not a requirement, especially due to internal RAM
size constraints.
IOMUXC and LPUART(using 24Mhz clock) work correctly using DM.
About clk drivers, I've seen all around that they are very shrinked
Linux's version drivers. Would it make sense to add complete clk driver
in u-boot starting from Linux one(i.e. vf610) or it would only grow
size? I mean, after adding initial support I would like to add Lcd
controller driver etc. etc. so a complete driver would be useful.
Instead what I see on IMX6 clk driver is only a subsection of all PLLs
and ref_sel to start Linux up.
I wait for your answer before proceeding with clk.
In the meanwhile I clean up and rebase then I begin adding sdram driver
for semc.
If you want you can take a look here:
https://github.com/giuliobenetti/u-boot/commits/imxrt-dts
btw I need to clean up everything and rebase, so at the moment it's a mess.
It's based on U-boot 2019.10
Best regards
