r350591:
Add a driver for Texas Instruments ADS101x/ADS111x i2c ADC chips.

Instances of the device can be configured using hints or FDT data.

Interfaces to reconfigure the chip and extract voltage measurements from
it are available via sysctl(8).

r350971:
Fix the driver name in ads111x.4, and hook the manpage up to the build.

The driver was originally written with the name ads1115, but at the last
minute it got renamed to ads111x to reflect its support for many related
chips, but I forgot to update the manpage to match the renaming before
committing it all.

r351724:
Fix the name of the devicetree bindings document file cited in the manpage.

The jedec_ts(4) driver has been marked as deprecated in stable/11, and is
now being removed from -HEAD. Add a notice in UPDATING, and update the few

Instead of building ofw_iicbus as a separate module, just compile it in to
the iicbus module for FDT-based systems.

The primary motivation for this is that host controller drivers which
declare DRIVER_MODULE(ofw_iicbus, thisdriver, etc, etc) now only need a
single MODULE_DEPEND(thisdriver, ofw_iicbus) for runtime linking to resolve
all the symbols. With ofw_iicbus and iicbus in separate modules, drivers
would need to declare a MODULE_DEPEND() on both, because symbol lookup is
non-recursive through the dependency chain. Requiring a driver to have
MODULE_DEPENDS() on both amounts to requiring the drivers to understand the
kobj inheritence details of how ofw_iicbus is implemented, which seems like
something they shouldn't have to know (and could even change some day).

Also, this is somewhat analogous to how the drivers get built when compiled
into the kernel. You don't have to ask for ofw_iicbus separately, it just
gets built in along with iicbus when option FDT is in effect.

jedec_dimm(4): report asset info and temperatures for DDR3 and DDR4 DIMMs

A super-set of the functionality of jedec_ts(4). jedec_dimm(4) reports asset
information (Part Number, Serial Number) encoded in the "Serial Presence
Detect" (SPD) data on JEDEC DDR3 and DDR4 DIMMs. It also calculates and
reports the memory capacity of the DIMM, in megabytes. If the DIMM includes
a "Thermal Sensor On DIMM" (TSOD), the temperature is also reported.

Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.

This driver supports only basic timekeeping functionality. It completely
replaces the ds133x driver. It can also replace the ds1374 driver, but that
will take a few other changes in MIPS code and config, and will be committed
separately. It does NOT replace the existing ds1307 driver, which provides
access to some of the extended features on the 1307 chip, such as controlling
the square wave output signal. If both ds1307 and ds13rtc drivers are
present, the ds1307 driver will outbid and win control of the device.

This driver can be configured with FDT data, or by using hints on non-FDT
systems. In addition to the standard hints for i2c devices, it requires
a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
(i.e., the same format as FDT compat strings).

Add a driver for the Intersil ISL12xx family of i2c RTC chips.

Supports ISL1209, ISL1218, ISL1219, ISL1220, ISL1221 (just basic RTC

Build iicbus/{ds1307,ds3231,nxprtc} as modules.

Restructure the SUBDIR list as 1-per-line and alphabetize, so it will be
easier to add new things (and see what changed) in the future.

jedec_ts: a driver for thermal sensors on memory modules

The driver currently supports chips that are fully compliant with the
JEDEC SPD / EEPROM / TS standard (JEDEC Standard 21-C,
TSE2002 Specification, frequenlty referred to as JEDEC JC 42.4).

Additionally some chips from STMicroelectronics are supported as well.
They are compliant except for their Device ID pattern.

Given the continued lack of any common sensor infrastructure, the driver
uses an ad-hoc sysctl to report the temperature.
