Subject: [PATCH 0/3 RFC] MMC SPI support for OpenFirmware platforms
Date: Thu, 30 Oct 2008 22:55:46 +0300	[thread overview]
Message-ID: <> (raw)

Hi all,

Here are the bindings, again. Still RFC.

This patch series depends on: 
+ of_gpio_flags enum (Trent Piepho will post an updated patch soon,
I believe).

Pierre, the approach is somewhat similar to this one:
Posted few months ago.

I know you don't like it, but I ask you to reconsider it. The
I2C and SPI cases are similar, and recently we tried to write
bindings for some I2C GPIO controllers.

There we've learned that we:

1. Don't like the bus notifiers approach b/c we can't place the OF
   code into the module.
   Hacks are possible, but they're are ugly.
2. Don't want to write new drivers to solely handle the platform

And personally I don't want to do refactoring for every driver that
we'd want to use with the OpenFirmware...

If I understood correctly, for GPIO controllers David agreed that
we can live with the platform data accessors, at least for now:

And when/if we'll find something better I'll be the first who
will offer help to convert the bindings code to this "something
