2013-11-15Merge branch 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/stagingLinus Torvalds1-97/+230
Pull hwmon fixes and updates from Jean Delvare: "All lm90 driver fixes and improvements" * 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging: Documentation: dt: hwmon: Add OF document for LM90 hwmon: (lm90) Add power control hwmon: (lm90) Add support for TI TMP451 hwmon: (lm90) Use enums for the indexes of temp8 and temp11 hwmon: (lm90) Add support to handle IRQ hwmon: (lm90) Define status bits hwmon: (lm90) Fix max6696 alarm handling
2013-11-15hwmon: (lm90) Add power controlWei Ni1-0/+19
The device lm90 can be controlled by the vcc rail. Adding the regulator support to power on/off the vcc rail. Enable the "vcc" regulator before accessing the device. [JD: Rename variables to avoid confusion with registers.] Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2013-11-15hwmon: (lm90) Add support for TI TMP451Wei Ni1-8/+37
TI TMP451 is mostly compatible with ADT7461, except for local temperature low byte and max conversion rate. Add support to the LM90 driver. Signed-off-by: Wei Ni <wni@nvidia.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2013-11-15hwmon: (lm90) Use enums for the indexes of temp8 and temp11Wei Ni1-64/+88
Using enums for the indexes and nrs of temp8 and temp11. This make the code much more readable. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2013-11-15hwmon: (lm90) Add support to handle IRQWei Ni1-0/+24
When the temperature exceed the limit range value, the driver can handle the interrupt. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2013-11-15hwmon: (lm90) Define status bitsWei Ni1-27/+61
Add bit defines for the status register. And add a function lm90_is_tripped() which will read status register and return tripped or not, then lm90_alert can call it directly, and in the future the IRQ thread also can use it. [JD: Adjusted to include all the new MAX6696 status flags.] Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2013-11-15hwmon: (lm90) Fix max6696 alarm handlingGuenter Roeck1-4/+7
Bit 2 of status register 2 on MAX6696 (external diode 2 open) sets ALERT; the bit thus has to be listed in alert_alarms. Also display a message in the alert handler if the condition is encountered. Even though not all overtemperature conditions cause ALERT to be set, we should not ignore them in the alert handler. Display messages for all out-of-range conditions.

Pull spi updates from Mark Brown: "As well as the usual driver updates and cleanups there's a few improvements to the core here: - The start of some improvements to factor out more of the SPI message loop into the core. Right now this is just simplifying the code a bit but hopefully next time around we'll also have managed to roll out some noticable performance improvements which drivers can take advantage of. - Support for loading modules for ACPI enumerated SPI devices. - Managed registration for SPI controllers. - Helper for another common I/O pattern" * tag 'spi-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (116 commits) spi/hspi: add device tree support spi: atmel: fix return value check in atmel_spi_probe() spi: spi-imx: only enable the clocks when we start to transfer a message spi/s3c64xx: Fix doubled clock disable on suspend spi/s3c64xx: Do not ignore return value of spi_master_resume/suspend spi: spi-mxs: Use u32 instead of uint32_t spi: spi-mxs: Don't set clock for each xfer spi: spi-mxs: Clean up setup_transfer function spi: spi-mxs: Remove check of spi mode bits spi: spi-mxs: Fix race in setup method spi: spi-mxs: Remove bogus setting of ssp clk rate field spi: spi-mxs: Remove full duplex check, spi core already does it spi: spi-mxs: Fix chip select control bits in DMA mode spi: spi-mxs: Fix extra CS pulses and read mode in multi-transfer messages spi: spi-mxs: Change flag arguments in txrx functions to bit flags spi: spi-mxs: Always clear INGORE_CRC, to keep CS asserted spi: spi-mxs: Remove mxs_spi_enable and mxs_spi_disable spi: spi-mxs: Always set LOCK_CS spi/s3c64xx: Add missing pm_runtime_put on setup fail spi/s3c64xx: Add missing pm_runtime_set_active() call in probe() ...

2013-10-19hwmon: (w83793) Clean up a signedness issueDan Carpenter1-1/+2

Its only caller, atxp1_storevcore(), doesn't use the return code but returns -1 instead, which is wrong anyway as it means -EPERM. Use the return value from vid_to_reg() instead to report the error.
