Hi, This series adds support for GMT G762/G763. This work is based on a basic version for 2.6.31 kernel developed Olivier Mouchet (kept as author for this reason in g762.c) for LaCie NAS. Updates have been performed to run on recent kernels. Supported has been completed and additional features added: ability to configure various characteristics from .dts file, better initialization, alarms and error reporting support, gear mode, polarity, fan pulse per revolution, fan startup voltage control. The following detailed datasheet has been used as a basis for this work: http://natisbad.org/NAS/refs/GMT_EDS-762_763-080710-0.2.pdf The patch was developed for and tested against the GMT G762 fan controller used in a Netgear ReadyNAS Duo v2 (kirkwood 88F6282-based NAS). This is the main reason for the device tree bindings provided in first patch. The patches are against current ARM tree; tell me if you need me to rebase it against something else. Patch 2 and 3 provides documentation for the driver and DT bindings, respectively. I hope the comments provided on v0 have all been correctly taken into account. A list of changes is provided below. Comments welcome, Cheers, a+ Changes since v0: Removed forward declaration Used bool for 'valid' field instead of bit field. Protected macro args Fixed typo in subject line Added mention for G763 support in Kconfig Fixed typo in driver name in Kconfig Do not use DRVNAME in i2c_device_id g762_id[] Following discussions, kept DEVICE_ATTR (i.e. no switch to SENSOR_DEVICE_ATTR) Removed useless casts when flipping bit values Sanity check user input value (e.g. to prevent 256 to silenty become 0) Added extra lines for multiline comments when needed Removed various testing knobs Make removed knobs available via DT Passed checkpatch script on the patch Removed useless lock protection againt clk setting Moved all setter at the beginning of the file Removed bad (u16) casts in g762_write_value() calls Added config structure and helpers Provide specific helper to overload config from dts Arnaud Ebalard (3): Add support for GMT G762/G763 PWM fan controller Add documentation for g762 driver Add DT documentation for g762 driver Documentation/devicetree/bindings/hwmon/g762.txt | 57 ++ Documentation/hwmon/g762 | 67 ++ drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/g762.c | 1058 ++++++++++++++++++++++ 5 files changed, 1193 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/g762.txt create mode 100644 Documentation/hwmon/g762 create mode 100644 drivers/hwmon/g762.c -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
