James" This series adds some functionality to the pmbus core. The first two patches provide support for the STATUS_WORD register. This allows more default alarm attributes to be used, as the upper byte of the status register is available. The third patch then uses the STATUS_INPUT bit of the status register to setup boolean attributes for input voltage and input power attributes. The fourth patch provides support for raw reads of pmbus status registers through the debugfs interface. These can be very useful for hardware diagnostics, especially on multi-page pmbus devices, as user-space access of the i2c space could corrupt the pmbus page accounting. Since v1: * Pull all debugfs stuff into pmbus_core.c to prevent problems when running without SENSORS_PMBUS. * Better boolean attr conditional. * Don't cache additional attributes, and display uncached registers for debugfs. * #ifdef around debugfs stuff. Since RFC series: * Just use u16 instead of complicated u8 method for STATUS_WORD. * Re-ordered the changes. * Added conditional for creating bool attr for higher byte STATUS_WORD bits. Edward A.
