With the new hwmon API, all attributes have to be created as groups.
Use sysfs_create_group and sysfs_remove_group instead of device_create_file
and device_remove_file to prepare for the new API.
Exception is the 'pec' attribute which will stay with the i2c device.

hwmon: (k10temp) Add support for AMD F16 M30h processor
- Merged in a branch of irqchip changes from Thomas
Gleixner: we need to have new callbacks from the
irqchip to determine if the GPIO line will be eligible
for IRQs, and this callback must be able to say "no".
After some thinking I got the branch from tglx and
have switched all current users over to use this.
- Based on tglx patches, we have added some generic
irqchip helpers in the gpiolib core. These will
help centralize code when GPIO drivers have simple
chained/cascaded IRQs. Drivers will still define
their irqchip vtables, but the gpiolib core will
take care of irqdomain set-up, mapping from local
offsets to Linux irqs, and reserve resources by
marking the GPIO lines for IRQs.
- Initially the PL061 and Nomadik GPIO/pin control
drivers have been switched over to use the new
gpiochip-to-irqchip infrastructure with more
drivers expected for the next kernel cycle. The
factoring of just two drivers still makes it worth
it so it is already a win.
- A new driver for the Synopsys DesignWare APB GPIO
block.
- Modify the DaVinci GPIO driver to be reusable also
for the new TI Keystone architecture.
- A new driver for the LSI ZEVIO SoCs.
- Delete the obsolte tnetv107x driver.
- Some incremental work on GPIO descriptors: have
gpiod_direction_output() use a logical level,
respecting assertion polarity through ACTIVE_LOW
flags, adding gpiod_direction_output_raw() for the
case where you want to set that very value. Add
gpiochip_get_desc() to fetch a GPIO descriptor from
a specific offset on a certain chip inside driver
code.
- Switch ACPI GPIO code over to using
gpiochip_get_desc() and get rid of gpio_to_desc().
- The ACPI GPIO event handling code has been reworked
after encountering an actual real life implementation.
- Support for ACPI GPIO operation regions.
- Generic GPIO chips can now be assigned labels/names
from platform data.
- We now clamp values returned from GPIO drivers to
the boolean [0,1] range.
- Some improved documentation on how to use the polarity
flag was added.
- The a large slew of incremental driver updates and
non-critical fixes. Some targeted for stable.
