From 51c2a4871c1b47255ff8d74f0a86b2a0defff319 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 12 Mar 2013 11:38:46 +0100 Subject: hwmon: (adt7410) Add support for the adt7310/adt7320 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.
