would it be possible to rename dts file to
microchip_mpfs_icicle_kit.dts? Dashes will not work with
SOC_BUILTIN_DTB_DECLARE(), and I do want to use built-in device tree
for XIP on Icicle. Thanks! :)
Best regards,
Vitaly

Please see the patch series I sent for the Canaan Kendryte K210 support: I want
to retire SOC_BUILTIN_DTB_DECLARE() as it is broken: the arch, vendor and imp ID
given by an SOC does not necessarily reflect the fact that the SoC is used on
different boards that need different DT. That makes differentiation of the
builtin DT for different boards using multiple SOC_BUILTIN_DTB_DECLARE()
declaration impossible. In short, SOC_BUILTIN_DTB_DECLARE() does not work.
http://lists.infradead.org/pipermail/linux-riscv/2020-December/003497.html
In the K210 series, I have this patch:
http://lists.infradead.org/pipermail/linux-riscv/2020-December/003498.html
that replaces SOC_BUILTIN_DTB_DECLARE() with a more traditional
BUILTIN_DTB_SOURCE config option. That is a lot more simple and a lot more solid.

Can you please change "microchip,pfsoc-clkcfg" to
"microchip,mpfs-clkcfg" to align with the v2 clock driver?

There is a newer version of U-Boot patch. Probably needs to sync again.

Add initial DTS for Microchip ICICLE board having only
essential devices (clocks, sdhci, ethernet, serial, etc).
The device tree is based on the U-Boot patch.
