| |
Changes since v1: - Dropped reduntant i2c-octeon change
i2c controller drivers used to assume bus number 0 when none (-1) was specified.
This worked on non-device tree systems, where one could explicitly specify bus number via platform data. On DT-enabled systems bus number is always -1.
This patchset reworks few remaining drivers to use dynamic bus allocation when no id has been provided.
[ I've found out this when I've tried to instantiate more than one i2c-gpio instance on DT-enabled system. I've, hopefully, fixed few other drivers too. ]
Karol Lewandowski (2): i2c-pxa: Drop leftover comment i2c: Dynamically assign adapter id if it wasn't explictly specified
