[PATCH v3 00/15] net: dsa: Fixes and enhancements

[Guenter Roeck <linux@roeck-us.net>]

Patch 01/15 addresses a bug indicated by an an annoying and unhelpful
log message.

Patches 02/15 and 03/15 are minor enhancements, adding support for
known switch revisions.

Patches 04/15 and 05/15 add support for MV88E6352 and MV88E6176.

Patch 06/15 adds support for hardware monitoring, specifically for
reporting the chip temperature, to the dsa subsystem.

Patches 07/15 and 08/15 implement hardware monitoring for MV88E6352,
MV88E6176, MV88E6123, MV88E6161, and MV88E6165.

Patch 09/15 and 10/15 add support for EEPROM access to the DSA subsystem.

Patch 11/15 implements EEPROM access for MV88E6352 and MV88E6176.

Patch 12/15 adds support for reading switch registers to the DSA
subsystem.

Patches 13/15 amd 14/15 implement support for reading switch registers
to the drivers for MV88E6352, MV88E6176, MV88E6123, MV88E6161, and MV88E6165.

Patch 15/15 adds support for reading additional RMON registers to the drivers
for  MV88E6352, MV88E6176, MV88E6123, MV88E6161, and MV88E6165.

The series was tested on top of v3.18-rc2 in an x86 system with MV88E6352.
Testing in systems with 88E6131, 88E6060 and MV88E6165 was done earlier
(I don't have access to those systems right now). The series was also build
tested using my build system at http://server.roeck-us.net:8010/builders.
Look into the 'dsa' column for build results.

The series merges cleanly into net-next as of today (10/29).

v3:
- Fix bug in eeprom patches seen if devicetree is enabled:
  eeprom-length property is attached to switch devicetree node,
  not to dsa node, and there was a compile error.
v2:
- Made reporting chip temperatures through the hwmon subsystem optional
  with new Kconfig option
- Changed the hwmon chip name to <network device name>_dsa<index>
- Made EEPROM presence and size configurable through platform and devicetree
  data
- Various minor changes and fixes (see individual patches for details)
