Re: [PATCH 1/1] ARM: dts: sunxi: Add a olinuxino-lime2-emmc

Hi Oliver,

I do: that 
http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7359
The syntax error seen there was fixed and the result is: 
http://forum.armbian.com/index.php/topic/853-armbian-customization/page-2#entry7361

The same tests was done on legacy kernel 3.4.111 modifying fex file and the 
result is the same:

Hi Olliver,

I have already test it a few weeks ago and definitely can say that 8-bit 
bus did not work on A20-Olinuxino-Lime2-eMMC with mainline kernel.
See may post here

.

I saw, but you forgot to define the pins for 4.x :)

See my patch from earlier:

Only 4 bits? We normally see eMMC with 8 bits. 4 bits are some kind

On A20 as well? Our investigations so far have concluded that the A10

A20 have those pins not mapped out to pads. The IP does support it

we assume. 

You're right. My bad. First time A10/A20 sees eMMC support. 

I can't say anything about A10/A20, but I have a board with A13 and 
the same eMMC chip and it works fine in 8 bit mode. 

Yep, sun5i actually brings them all out to pads, the A20 however does 
not :( We first thought that the A20 would also be an 8bitter, because 
the mmc IP appears to be the same as sun5i, but initial tests show it is 
not. As for A10, it has older IP and it might not even support 8 bit 
mode, let alone bring out the pins. 

But with A20's + eMMC being available via the lime2, others may repeat 
my experiments! The lime2 is 8 bit connected.
