2012-12-19hwmon: (w83627hf) Don't touch nonexistent I2C address registersJean Delvare
Only the W83627HF could be accessed through I2C. All other supported chips are LPC-only, so they do not have I2C address registers. Don't write to nonexistent or reserved registers on these chips. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <linux@roeck-us.net>

2012-12-19hwmon: (w83627hf) Add support for suspendJean Delvare
On suspend some register values are lost, most notably the Value RAM areas but also other limits. Restore them on resume. On top of that, some fixups are needed to work around BIOS bugs, in particular when the BIOS omits running the same initialization sequence on resume that it does after boot. In that case we have to carry initialization over suspend. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <linux@roeck-us.net> Tested-by: Guenter Roeck <linux@roeck-us.net>

2012-12-05hwmon: (coretemp) Drop dependency on PCI for TjMax detection on Atom CPUsGuenter Roeck
So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping (x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs with TjMax of 100 degrees C. This was verified by checking the output of /proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx). Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90 degrees C, except for E6xxT models which have a TjMax of 110 degrees C. E6xxT CPUs can however not be detected by software. Calculate TjMax for Atom CPUs as follows. Note that the listed values are not correct in some cases (230, 330). tjmax_table is used for those to override the default values. ID Stepping TjMax Models 0x1c 10 100 D4xx, N4xx, D5xx, N5xx 0x1c not 10 90 Z5xx, N2xx, 230, 330, others 0x26 - 90 Atom Tunnel Creek (Exx), Lincroft (Z6xx) 0x27 - 90 Atom Medfield (Z2460) 0x36 - 100 Atom Cedar Trail (N2xxx, D2xxx) Also drop the module dependency on PCI.

As there is no reliable way to identify the chip, it is preferable to remove the detect callback, to avoid misdetection. Module parameters are not worth it here, so let's get rid of them and add an ads7828_platform_data structure instead.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while.

This movement is needed because the hwmon entries and corresponding sysfs interface is a duplicate of utilities already provided by driver/thermal/thermal_sys.c. The goal is to place it in thermal folder and add necessary functions to use the in-kernel thermal interfaces.

2012-09-24hwmon: (lm70) Simplify show_name functionGuenter Roeck
Instead of using a switch statement to determine the device name, use to_spi_device(dev)->modalias to simplify the code and reduce module size. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2012-09-24hwmon: (adcxx) Simplify show_name functionGuenter Roeck
Display device name using to_spi_device(dev)->modalias instead of computing it from the number of ADC channels. This is cleaner and reduces code size. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
