Subject: [PATCH v3 7/7] mtd: rawnand: ams-delta: use GPIO API for data I/O
Date: Tue, 14 Aug 2018 00:34:48 +0200 [thread overview]
Message-ID: <20180813223448.21316-8-jmkrzyszt@gmail.com> (raw)
In-Reply-To: <20180813223448.21316-1-jmkrzyszt@gmail.com>
Don't readw()/writew() data directly from/to GPIO port which is under
control of gpio-omap driver, use GPIO API instead.
Degrade of performance on Amstrad Delta is significant, can be
recognized as a regression, that's why I'm still submitting this patch
as RFC.
The driver should work with any 8+-bit bidirectional GPIO port, not
only OMAP.

I think most of the overhead is in iterations performed both inside and
outside get/set array functions:
- building a mask for get_multiple() and transfering results to value array
in gpiod_get_array_value_complex(), then again from the array by a caller,
- building a value array by the caller, the building a mask and tranferiing
values from array to bitmap for .set_multiple() in
gpiod_set_array_value_comples().
Thanks,
Janusz
