This patch series adds support to show and change the bus frequency via sysfs, by exposing files to show the minimum, maximum and current frequency as well as allowing the frequency to be changed. This allows the user to view or change the bus frequency on a per bus level. Changes since v3: * use DEVICE_ATTR_RO and make i2c_adapter_visible_attr static * implement sysfs bus frequency support for the diolan u2c bus Octavian Purdila (4): i2c: document the existing i2c sysfs ABI i2c: document struct i2c_adapter i2c: show and change bus frequency via sysfs i2c: i2c-diolan-u2c: sysfs bus frequency support Documentation/ABI/testing/sysfs-bus-i2c | 75 +++++++++++++++++++++++++++ drivers/i2c/busses/i2c-diolan-u2c.c | 49 ++++++++++++------ drivers/i2c/i2c-core.c | 90 +++++++++++++++++++++++++++++++++ include/linux/i2c.h | 32 ++++++++++-- 4 files changed, 228 insertions(+), 18 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-i2c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
