The I2C subsystem should be able to match via other means, such as via OF tables. The blocking factor during our previous conversation was to keep registering via sysfs up and running. This set does that. After thinking more deeply about the problem, it occurred to me that any I2C device driver which uses the sysfs method and issues an of_match_device() would also fail their probe(). Bolted on to this set is a new, more generic way for these devices to match against either of the I2C/OF tables. I hope this ticks all of your boxes. v2: - Removal of ACPI support (this is really an OF issue). - Add a new .probe2( with will seamlessly replace - Supply a warning on devices matching via OF without a suitable compatible - Remove unified match_device() - bad idea as it subverts type-safe behaviour - Provide examples of the kind of clean-up possible after this set. - I already have the full support from the maintainer of these drivers =;-) Kind regards, Lee drivers/i2c/i2c-core.c | 73 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++--------- drivers/mfd/88pm860x-core.c | 5 ++--- drivers/mfd/as3722.c | 12 ++---------- drivers/of/device.c | 19 ++++++++++++++++++- include/linux/i2c.h | 29 ++++++++++++++++++++++++++++- 5 files changed, 114 insertions(+), 24 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
