Simplify the code and reduce its size by using is_visible to determine
valid attributes, and sysfs_create_group to create all of them with
a single call.Signed-off-by: Guenter Roeck

Some sysfs attributes are only supported on LTC2978 and not on LTC3880.
Update documentation to reflect which attributes are supported for which chips.Output current attributes supported on LTC3880 were described as providing
input current values. Fix text to reflect that the attributes provide output
current values."reset history" attribute descriptions were misleading and seemed to imply
that all history was reset when writing a single attribute. Replace with more
accurate text.Replace 'internal temperature" with "chip temperature". Temperature limits
not only apply to the chip temperature, but also to external temperatures
on LTC3880, so remove the word "chip" from the attribute description.Signed-off-by: Guenter Roeck

Use u16 instead of int to store cached limit attributes.
This reduces allocated data size per driver instance by 48 bytes.
Use defines for the number of pages supported by individual chips.
Use ARRAY_SIZE for loops to initialize array variables, and
initialize all variables in the same code block.Signed-off-by: Guenter Roeck

The read/write lock is acquired for each read/write operation from/to the chip.
This occurs either during initialization, when it is not needed, or during
updates, when the update_lock is held as well, and it is not needed either.Signed-off-by: Guenter Roeck

This patch adds DT support to NTC driver to parse the
platform data.Also adds the support to work as an iio device client.
During the probe ntc driver gets the respective channels of ADC
and uses iio_raw_read calls to get the ADC converted value.Signed-off-by: Naveen Krishna Chatradhi

The adt7310/adt7320 is the SPI version of the adt7410/adt7420. The register map
layout is a bit different, i.e. the register addresses differ between the two
variants, but the bit layouts of the individual registers are identical. So both
chip variants can easily be supported by the same driver. The issue of non
matching register address layouts is solved by a simple look-up table which
translates the I2C addresses to the SPI addresses.The patch moves the bulk of the adt7410 driver to a common module that will be
shared by the adt7410 and adt7310 drivers. This common module implements the
driver logic and uses a set of virtual functions to perform IO access. The
adt7410 and adt7310 driver modules provide proper implementations of these IO
accessor functions for I2C respective SPI.Signed-off-by: Lars-Peter Clausen

Currently each time the temperature register is read the driver also reads the
threshold and hysteresis registers. This increases the amount of I2C traffic and
time needed to read the temperature by a factor of ~5. Neither the threshold nor
the hysteresis change on their own, so once we have read them, we should be able
to just use the cached value of the registers. This patch modifies the code
accordingly and only reads the threshold and hysteresis registers once during
probe.Signed-off-by: Lars-Peter Clausen

Due to all of the goodness being packed into today's kernels, the
resulting image isn't as slim as it once was.In light of this, don't pass -msmall-data to gcc, which otherwise results
in link failures due to impossible relocations when compiling anything but
the most trivial configurations.Cc: Richard Henderson

This patch adds support for kvm_gfn_to_hva_cache_init functions for
reads and writes that will cross a page. If the range falls within
the same memslot, then this will be a fast operation. If the range
is split between two memslots, then the slower kvm_read_guest and
kvm_write_guest are used.Tested: Test against kvm_clock unit tests.
