Subject: [PATCH] w100fb: Rewrite for platform independence
X-Git-Tag: v2.6.14-rc1~581
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=aac51f09d96a0acfb73c1d1c0796358bb47ea07b;p=linux-2.6-omap-h63xx.git

[PATCH] w100fb: Rewrite for platform independence

The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
was little else that could be done as I had no access to anything else with
a w100 in it.  There is no real documentation about this chipset available.

Ian Molton has access to other platforms with the w100 (Toshiba e-series)
and so between us, we've improved w100fb and made it platform independent.
Ian Molton also added support for the very similar w3220 and w3200
chipsets.

There are a lot of changes here and it nearly amounts to a rewrite of the
driver but it has been extensively tested and is being used in preference
to the original driver in the Zaurus community.  I'd therefore like to
update the mainline code to reflect this.
