2015-05-27mfd: da9052: Fix broken regulator probeJohan Hovold
Fix broken probe of da9052 regulators, which since commit b3f6c73db732 ("mfd: da9052-core: Fix platform-device id collision") use a non-deterministic platform-device id to retrieve static regulator information. Fortunately, adequate error handling was in place so probe would simply fail with an error message. Update the mfd-cell ids to be zero-based and use those to identify the cells when probing the regulator devices.

2015-05-06can: janz-ican3: add support for CAL/CANopen firmwareAndreas Gröger
In our department we are using some older Janz ICAN3-modules in our dekstop pcs. There we have slightly different carrier boards than the janz-cmodio supported in the kernel sources, called CAN-PCI2 with two submodules. But the pci configuration regions are identical. So extending the supported pci devices to the corresponding device ids is sufficient to get the drivers working. * The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart after reset. I've increased the timeout to 500ms. * The janz_ican3 module uses the raw can services of the Janz-firmware, this means firmware must be ICANOS/2. Our ICAN3-modules are equipped with CAL/CANopen-firmware, so I must use the appropriate commands for the layer management services. Te driver detects the firmware after module reset and selects the commands matching the firmware. This affects the bus on/off-command (ican3_set_bus_state) and the configuration of the bittiming (ican3_set_bittiming). For better diagnostics the detected firmware string is presented as sysfs attribute (fwinfo).

Main new things this cycle is: - Driver changes to expose the lightbar to users. With this, you can make your own blinkenlights on Chromebook Pixels. - Changes in the way that the atmel_mxt trackpads are probed. The laptop driver is trying to be smart and not instantiate the devices that don't answer to probe. For the trackpad that can come up in two modes (bootloader or regular), this gets complicated since the driver already knows how to handle the two modes including the actual addresses used. So now the laptop driver needs to know more too, instantiating the regular address even if the bootloader one is the probe that passed. - mfd driver improvements by Javier Martines Canillas, and a few bugfixes from him, kbuild and myself" * tag 'chrome-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/chrome-platform: platform/chrome: chromeos_laptop - instantiate Atmel at primary address platform/chrome: cros_ec_lpc - Depend on X86 || COMPILE_TEST platform/chrome: cros_ec_lpc - Include linux/io.h header file platform/chrome: fix platform_no_drv_owner.cocci warnings platform/chrome: cros_ec_lightbar - fix duplicate const warning platform/chrome: cros_ec_dev - fix Unknown escape '%' warning platform/chrome: Expose Chrome OS Lightbar to users platform/chrome: Create sysfs attributes for the ChromeOS EC mfd: cros_ec: Instantiate ChromeOS EC character device platform/chrome: Add Chrome OS EC userspace device interface platform/chrome: Add cros_ec_lpc driver for x86 devices mfd: cros_ec: Add char dev and virtual dev pointers mfd: cros_ec: Use fixed size arrays to transfer data with the EC

2015-04-09mfd: sec: Fix RTC alarm interrupt number on S2MPS11Krzysztof Kozlowski
The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of RTC alarms 0 and 1 were inversed between these two devices. So when rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to S2MPS11_IRQ_RTCA1, not RTCA0. Fix this by using consistent RTC alarm interrupt numbers and adding a BUILD_BUG_ON for future generations.

2015-03-30mfd: core: Fix platform-device name collisionsJohan Hovold
Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when registering mfd-devices. Unfortunately, some mfd-drivers rely on the old behaviour of generating platform-device ids by adding the cell id also to the special value of PLATFORM_DEVID_NONE. The resulting platform ids are not only used to generate device-unique names, but are also used instead of the cell id to identify cells when probing subdevices. These drivers should be updated to use PLATFORM_DEVID_AUTO, which would also allow more than one device to be registered without resorting to hacks (see for example wm831x), but lets fix the regression first by partially reverting the above mentioned commit with respect to PLATFORM_DEVID_NONE.

2015-03-12mfd: rk808: Disable the under voltage detectChris Zhong
Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck. So let's disable this function. Signed-off-by: Chris Zhong <zyw@rock-chips.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2015-03-12mfd: rt5033: MFD_RT5033 needs to select REGMAP_IRQArtem Savkov
Since commit 0b2712585(linux-next.git) this driver uses regmap_irq and so needs to select REGMAP_IRQ. This fixes the following compilation errors: ERROR: "regmap_irq_get_domain" [drivers/mfd/rt5033.ko] undefined! ERROR: "regmap_add_irq_chip" [drivers/mfd/rt5033.ko] undefined!

2015-03-12mfd: da9052: Fix register access via SPIAdam Ward
The range of registers used by this driver exceeds that available via SPI with no paging (127), so we have to override the values from the default config which is set-up for I2C access. Also change SPI settings to match device's recommended OTP values. Signed-off-by: Adam Ward <adam.ward.opensource@diasemi.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
