[PATCH v2 2/3] arm64: dts: armada-3720-espressobin: split common parts to .dtsi

[Andre Heider]

Move most of the dts to the new common armada-3720-espressobin.dtsi
file, just like Linux, but keep the current, downstream based, version.

The dts itself is imported from Linux.

[PATCH v2 3/3] arm64: dts: a3720: add support for espressobin with populated emmc

[Andre Heider]

Import armada-3720-espressobin-emmc.dts from Linux, but use sdhc1 for
emmc, since our dtsi is still based on downstream and sdhc0 is used for
the sd card.

We've found a tester with an eMMC board, and unfortunately this patch is 
not sufficient. eMMC shows up, but accessing it errors out with "MMC: no 
card present".

Stefan, please ignore 3/3 for now.
If you agree, 1/3 and 2/3 are still worth having, they prepare for 
syncing dts files with Linux.

Regards,
Andre

Thanks to G?rald we managed to fix it. 3/3 is good to go, the missing 
piece was just respecting "non-removable", see [0].

That patch combined with this set makes it work, so please go ahead and 
review :)

Thanks,
Andre

Hello! Does not it really make sense to do autodetection of eMMC
presence and enable it in U-Boot code only when needed and therefore
avoid having two DTS files and needs for specifying DEVICE_TREE variable
and therefore variant of Espressobin, as I stated in previous emails?

I think this just complicates build process... E.g. we already have a
code in U-Boot which detects V5 vs V7 variant.

I still like the idea, but I'm still hesitating to just enable the emmc 
everywhere. There's the issue with powering down the emmc block if it's 
not populated. How would that work once we switch to atf for comphy control?

 From a different angle: If we could just do that, why does Linux have 
different devicetrees?

Andre

Is there issue with powering it down? I just do not know about it. And
could we fix it?

I do not know exact answer, so I just guess two reasons:

1) historic, nobody wanted to think about it, so rather created
secondary DTS

2) linux driver model does not have API and solution how to do this
auto-detection and in case of absence, turn blocks off and reconfigure
it.

IIRC similar problem was with MOX (also based on A3720) and final
solution is that kernel has only one DTB and U-Boot "modifies" it prior
booting kernel, based on autodetection which U-Boot did. Similarly like
MAC address of MTD partitions are put into espressobin DTB prior booting
kernel.

MOX has uSD slot for uSD card and SDIO slot for SDIO wifi card, both
removable. Standard product configuration does not contain SDIO wifi
card, but kernel's DTS file have it enabled by default:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/marvell/armada-3720-turris-mox.dts

So it is really problem to enable eMMC by default on espressobin?
