| |
Hi all,
Here are the bindings, again. Still RFC.
This patch series depends on: http://lkml.org/lkml/2008/10/16/250 http://lkml.org/lkml/2008/10/24/416 + of_gpio_flags enum (Trent Piepho will post an updated patch soon, I believe).
Pierre, the approach is somewhat similar to this one: http://lkml.org/lkml/2008/5/26/135 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. http://lkml.org/lkml/2008/10/21/425 Hacks are possible, but they're are ugly. 2. Don't want to write new drivers to solely handle the platform data: http://lkml.org/lkml/2008/10/28/257 http://lkml.org/lkml/2008/10/28/268
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: http://lkml.org/lkml/2008/10/23/24
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 better".
Thanks,
