Hi,
This series syncs AM64 DT files from Linux v6.5-rc1.
Tested on AM642-EVM GP SR1.0 and AM642-SK-EVM HS-FS SR2.0.
Couldn't verify Linux boot on AM642-SK-EVM so would appreciate
if someone can give a Tested-by for that. Thanks!
cheers,
-roger
Changelog:
v3:
- include board DT file in -r5 DT file.
- move including -u-boot.dtsi file at the top of -r5 DT file.
- drop duplicate nodes
- document why we need to delete clock/power properties from
main_timer0
v2:
- Sync with v6.5-rc1
- Rebase on latest uboot/master
- CPSW node cleanup
- Timer node cleanup

AM64-HSEVM is AM64-GPEVM with High Security Device.
Gets rid of "Unidentified board claims AM64-HSEVM in eeprom header".

This reverts commit 28a4c3113445d4400639f357fae0def007a41093.
This node should be in the board DT file and should come from upstream.
Moreover, this PMIC is no present on all variants of am642-sk
and will need a separate board DT file.

Sync all am642-evm/am642-sk related DT files
with Linux v6.5-rc1.
- drop timer1 in favor of main_timer0 in am64-main.dtsi.
Need to delete clock & power domain properties of
main_timer1 in -r5.dts else won't boot. This is because
timer_init is done during rproc_start to start System Firmware,
but we can't do any clock/power-domain operations before
System Firmware starts.
- drop cpsw3g custom DT property 'mac_efuse' and custom
DT node cpsw-phy-sel as driver picks these from standard
property/node.
- include board dts file in -r5 dts file to avoid duplication
of nodes. Include -u-boot.dtsi on top.
- drop duplicate nodes in -r5 dts and -u-boot.dtsi

if that is the argument for main_uart0 and main_i2c0 main_gpio0 etc.
- please document in the r5.dts as well as to why we are
/delete-property/ power-domains. I think we feed in boardconfig etc by
the time we get around to this, correct? if not, we might need to state
that information - that without boardconfig being fed to the sysfw pm
functions are'nt active.
Otherwise, this is coming along just right.

Please drop this entirely -> If you look at proc schematics
https://www.ti.com/tool/TMDS64GPEVM#design-files
MMC0_CLK is G18, MMC0_DAT0 is K20 and so on. This matches with what we
see in
dev.ti.com/sysconfig tool as well and the data sheet - these pins have a
single mux mode - that is MMC, no specific register exists for override.
infact B25 as a pin does'nt even exist on the package.
you also want to fix the reference in arch/arm/dts/k3-am642-r5-evm.dts

no you aren't looking at the wrong svg files: because

Right. Also vtt_supply is always-on fixed regulator.
So will drop vtt-supply property from memory_controller node.

I added them in -u-boot.dtsi along with cbass_main and cbass_mcu.
Should I move them to -r5-sk instead?

I got rid of /delete-property/ for main_i2c0 and main_gpio0 and
didn't see any ill effects. So will drop them from there.
Looks like we need to have it only for main_uart0 and main_timer0.
I'll add a comment for main_uart0.
