Subject: nand: denali: issue with 4.13
Date: Thu, 21 Sep 2017 08:44:06 +0200	[thread overview]
Message-ID: <25edd455-ad6c-f222-f552-2aa3d807112a@pengutronix.de> (raw)

Hi Masahiro,

you are probably the expert of denali nand driver.
With kernel v4.13 i have following issue, it works on FPGASoC 
5CSEBA5U... but is now working on FPGASoC 5CSXFC6C6U... both of them 
have same NAND chip, and seems to have similar IP core.

FPGASoC 5CSXFC6C6U...:

Initially both of SoCs worked with this patch:
commit 9a10df06caeecf39ceb32193c41a3b42c4b7cac3
Author: Graham Moore <grmoore@altera.com>
Date:   Mon Oct 28 11:01:37 2013 -0500

     FogBugz #163905: Support Denali NAND driver on socfpga platform


At least part of this patch is upstreamed. Are there any other pending, 
WIP patches on the way? Any of them covering this issue?

Thank you for work!
Kind regards,
Oleksij
