[PATCH 0/7] dts: sunxi: Add sunxi NAND Flash Controller support

[Aleksei Mamlin]

Hello,

This series adds the sunxi NAND Flash Controller nodes to dts.

The first 4 patches is Boris Brezillon's patches with dtsi changes.
The second 1 patch adds Hynix H27UBG8T2BTR-BC NAND chip definition.
The last 2 patches enables NAND on Marsboard A10 board and Wexler TAB7200
tablet.

Aleksei Mamlin (3):
  mtd: nand: Add Hynix H27UBG8T2BTR-BC to nand_ids table
  ARM: dts: sun4i: Enable NAND on Marsboard A10
  ARM: dts: sun7i: Enable NAND on Wexler TAB7200

Boris Brezillon (4):
  ARM: dts: sun4i: Add A10 NAND controller pin definitions
  ARM: dts: sun4i: Add NFC node to Allwinner A10 SoC
  ARM: dts: sun7i: Add A20 NAND controller pin definitions
  ARM: dts: sun7i: Add NFC node to Allwinner A20 SoC

We usually enable only the pin groups that are actually used by some
board to avoid bloating the DT too much.

And the nodes should be sorted alphabetically.

Still hoping to get this series [1] merged in 4.8, but if that's
not the case, I'll apply your patch.

BTW, that would be great if you could test it on your platforms.

It seems that Hynix-specific initialization code can't handle H27UBG8T2BTR-BC
chip:

Can you try this patch? It should fix the problem [1].

It should be ignored: your NAND is not 'ONFI compatible', the datasheet
just says that it supports the' ONFI command set', which is not the
same :).
The trace you're seeing here is just notifying that the core failed to
detect an ONFI NAND, which is expected in your case.

Brian, I have a question regarding the extended NAND ids (not full-ids)
defined in the nand_ids table. Are they really valid for all vendors?

If that's the case, why are we extracting the bus width from the id[3]
since we already have this information in the options field?

This feels a bit premature. The two boards you're using have an MLC
NAND which is not supported yet. Until there's proper MLC support in
the kernel, I'm not sure we want to enable that for end-users when we
know that things will get wrong.

However, after discussing this with Boris, I appreciate that we don't
have any example available because of this policy for people that want
to opt-in anyway.

What we could do is to still mark the status as disabled in the DTS,
with a big fat warning as comment just before, so that it requires
user action, and that user will have been warned.

Would that work for you?

Let's drop this two patches with boards dts changes until we get proper MLC
support in kernel.

As for examples - I'll update linux-sunxi wiki with how to enable NAND 
controller and describe NAND chips in DTS. People who want to add NAND support 
to their boards will be warned that it is risky for now.

[PATCH v2 0/4] dts: sunxi: Add sunxi NAND Flash Controller support

[Aleksei Mamlin]

Hello,

This series adds the sunxi NAND Flash Controller pin definitions and nodes to
dts.

Changes since v1:
- Remove patch with Hynix H27UBG8T2BTR-BC MLC NAND chip definition.
- Remove patches with NAND support on Marsboard A10 board and Wexler TAB7200.
- Enable only the pin groups that are actually used by sunxi boards.
- Enable DMA support. Depends on sunxi NFC DMA support([1], [2]), merged into
  linux-nand.

Unfortunately, we don't have any user for it at the moment.

Please re-submit it later when we'll have some :)
