This was suggested by Mark Brown in response to a patch for adding this functionality only for the s3c2410 bus: https://lkml.org/lkml/2012/11/20/681 I have also modified the i2c-pxa driver to use this new functionality. As Haojian Zhuang has Acked this patch, I believe that this has now been tested. Reposting (with Haojian Zhuang's ack) in the hopes that a maintainer will pick it up. :) Doug Anderson (2): i2c-core: dt: Pick i2c bus number from i2c alias if present i2c: pxa: Use i2c-core to get bus number now drivers/i2c/busses/i2c-pxa.c | 8 +--- drivers/i2c/i2c-core.c | 105 ++++++++++++++++++++++++++++++----------- 2 files changed, 78 insertions(+), 35 deletions(-) -- 1.7.7.3 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
