Commit 28c015a9daabe4e ("mtd: davinci-nand: disable subpage write for
keystone-nand") disables subpage write for Keystone SOCs due to hw
issues.
But subpage writes doesn't work even for DaVinci SOCs due to hw issues.
So set NAND_NO_SUBPAGE_WRITE option for all devices compatible to
this driver.
I tested this patch using DA850 board.

Hi Sushaanth,
Sorry for the late reply, I'm dequeing old NAND related patches and
found this one.
Is this patch still needed?

I dont think so. I suspect the real root cause was addressed by Karl in
commit f6d7c1b5598b ("mtd: nand: davinci: Reinitialize the HW ECC
engine in 4bit hwctl")
I just ran mtd_subpagetest on my da850 lcdk board and it passed[1]. If
there are more tests to run to determine if subpage write really works,
let me know too.
I suspect even the original workaround for keystone boards may not be
needed after Karl's patch. I will test and send a patch dropping the
workaround altogether if the tests succeed.
Thanks,
Sekhar

Okay, cool. I'll just mark the patch as 'Superseeded' in patchwork.

No, that should be good.
