2013-05-02Merge tag 'cleanup-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanup from Olof Johansson: "Here is a collection of cleanup patches. Among the pieces that stand out are: - The deletion of h720x platforms - Split of at91 non-dt platforms to their own Kconfig file to keep them separate - General cleanups and refactoring of i.MX and MXS platforms - Some restructuring of clock tables for OMAP - Convertion of PMC driver for Tegra to dt-only - Some renames of sunxi -> sun4i (Allwinner A10) - ... plus a bunch of other stuff that I haven't mentioned" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (119 commits) ARM: i.MX: remove unused ARCH_* configs ARM i.MX53: remove platform ahci support ARM: sunxi: Rework the restart code irqchip: sunxi: Rename sunxi to sun4i irqchip: sunxi: Make use of the IRQCHIP_DECLARE macro clocksource: sunxi: Rename sunxi to sun4i clocksource: sunxi: make use of CLKSRC_OF clocksource: sunxi: Cleanup the timer code ARM: at91: remove trailing semicolon from macros ARM: at91/setup: fix trivial typos ARM: EXYNOS: remove "config EXYNOS_DEV_DRM" ARM: EXYNOS: change the name of USB ohci header ARM: SAMSUNG: Remove unnecessary code for dma ARM: S3C24XX: Remove unused GPIO drive strength register definitions ARM: OMAP4+: PM: Restore CPU power state to ON with clockdomain force wakeup method ARM: S3C24XX: Removed unneeded dependency on CPU_S3C2412 ARM: S3C24XX: Removed unneeded dependency on CPU_S3C2410 ARM: S3C24XX: Removed unneeded dependency on ARCH_S3C24XX for boards ARM: SAMSUNG: Fix typo "CONFIG_SAMSUNG_DEV_RTC" ARM: S5P64X0: Fix typo "CONFIG_S5P64X0_SETUP_SDHCI" ...

2013-04-09staging:iio:adt7316 Fix some 'interesting' string operationsLuck, Tony
Calling memcmp() to check the value of the first byte in a string is overkill. Just use buf[0] == '1' or buf[0] != '1' as appropriate. Signed-off-by: Tony Luck <tony.luck@intel.com> Acked-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-04-02iio:magnetometer:ak8975 move driver out of stagingJonathan Cameron
Issues raised in last series to propose this have now been resolved so there should be no reason this driver cannot graduate from staging. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>
2013-04-02staging:iio:magnetometer:ak8975 use standard i2c_smbus read functions.Jonathan Cameron
Now the mysterious NOSTART flag is gone from the read, we can use the i2c_smbus_read_byte/word/i2c_block_data functions instead of the local reimplementation of these standard functions. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>
2013-04-02staging:iio:magnetometer:ak8975 drop I2C_M_NOSTART flag in read_dataJonathan Cameron
This flag makes no sense whatsoever where it is. Documentation/i2c/i2c-protocol states: If you set the I2C_M_NOSTART variable for the first partial message, we do not generate Addr, but we do generate the startbit S. This will probably confuse all other clients on your bus, so don't try this. This is exactly what is going on here. Likelihood given that the driver never checked for this protocol mangling being available is that it wasn't present on the test boards and hence this flag was simply ignored. No indication of why it would be necessary has been found in the datasheets. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>

2013-03-29iio: mxs-lradc: Do hardware initialization earlierAlexandre Belloni
We need to initialize hardware before registering the touchscreen. Else, we end up setting registers in mxs_lradc_ts_open(), getting called just after registering the touchscreen with input_register_device() and by the end of mxs_lradc_probe(), we reset the LRADC block hence losing the correct configuration.

2013-03-29staging:iio:ad799x: Preallocate sample bufferLars-Peter Clausen
Avoid allocating and freeing the sample buffer for each transfer. Instead allocate it once when we start sampling. Also pre-compute the number of bytes we need to transfer in the same way. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-03-29staging:iio:ad799x: Set IIO_CHAN_INFO_SCALE maskLars-Peter Clausen
The driver has support for reporting a channels scale, but none of the channels set the IIO_CHAN_INFO_SCALE mask. Add the IIO_CHAN_INFO_SCALE to all channels to indicate that the drivers supports reporting the scale.

2013-03-25iio:trigger: Introduce iio_tigger_{set,get}_drvdataLars-Peter Clausen
Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific data to a trigger. The functions wrap access to the triggers private_data field and all current users are updated to use iio_tigger_{set,get}_drvdata instead of directly accessing the private_data field. This is the first step towards removing the private_data field from the iio_trigger struct.

2013-03-23hwmon: Move the IIO client driver for hwmon out of stagingJonathan Cameron
This driver uses channel maps, defined either through device tree or platform data, to create a hwmon driver which acts as a client for the underlying IIO device channels. Thus a general purpose IIO adc driver can be used to provide hardware monitoring using a subset of its channels. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Guenter Roeck <linux@roeck-us.net> -- The only non move changes here concern the description and changes to the dependencies to IIO explicit and hwmon implicit. I'm proposing moving this into hwmon on the basis of placing drivers based on what they provide rather than what their underlying hardware is. drivers/hwmon/Kconfig | 9 ++ drivers/hwmon/Makefile | 1 + drivers/hwmon/iio_hwmon.c | 196 ++++++++++++++++++++++++++++++++++++++++ drivers/staging/iio/Kconfig | 8 -- drivers/staging/iio/Makefile | 2 - drivers/staging/iio/iio_hwmon.c | 196 ---------------------------------------- 6 files changed, 206 insertions(+), 206 deletions(-)

So far, all instances of iio_hwmon set their hwmon name attribute to "iio_hwmon", which is not very descriptive.
