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.
Yes, since you are adding this from scratch, I would suggest adding a complete clock driver, which is close to the Linux driver.
With this you mean adding every single mux, divider, gate, fixed_factor and pfd(i.e. linux/drivers/clk/imx/clk-imxq6.c)?
Or only a shrinked version of that? I mean, is it ok if I list everything during imxrt_clk_probe()?
Thanks in advance
