* mfd: axp20x: Support AXP803 variantIcenowy Zheng2017-04-272-0/+80
| | | | | | | | | | | | | AXP803 is a new PMIC chip produced by X-Powers, usually paired with A64 via RSB bus. The PMIC itself is like AXP288, but with RSB support and dedicated VBUS and ACIN. Add support for it in the axp20x mfd driver. Currently only power key function is supported. Signed-off-by: Icenowy Zheng <icenowy@aosc.io> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: intel_soc_pmic_core: Fix unchecked return valuePan Bian2017-04-271-0/+3
| | | | | | | | | | unction devm_regmap_init_i2c() returns an ERR_PTR on errors, and its return value should be checked before it is dereferenced. However, in function intel_soc_pmic_i2c_probe(), the return value of function devm_regmap_init_i2c() is used without validation. This patch fixes it.

* mfd: omap-usb-tll: Fix inverted bit use for USB TLL modeTony Lindgren2017-04-271-1/+1
| | | | | | | | | | | | | | | | Commit 16fa3dc75c22 ("mfd: omap-usb-tll: HOST TLL platform driver") added support for USB TLL, but uses OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF bit the wrong way. The comments in the code are correct, but the inverted use of OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF causes the register to be enabled instead of disabled unlike what the comments say. Without this change the Wrigley 3G LTE modem on droid 4 EHCI bus can be only pinged few times before it stops responding.

| | | | | | | | | | | | | | | | | | | | Crystal Cove and Whiskey Cove are two different PMICs which are installed on Intel Atom SoC based platforms. Moreover there are two independent drivers that by some reason were supposed (*) to get into one kernel module. Fix the mess by clarifying Kconfig option for Crystal Cove and split Whiskey Cove out of it. (*) It looks like the configuration was never tested with INTEL_SOC_PMIC=n.

* mfd: exynos-lpass: Add support for clocksMarek Szyprowski2017-04-271-0/+10
| | | | | | | | | | | | | | | | | | | Exynos LPASS requires some clocks to be enabled to make any access to its registers. This patch adds code for handling such clocks. For current set of registers it is enough to keep sfr0_ctrl clock enabled. Till now it worked only because those clocks were enabled by bootloader and driver probe() happened before they were disabled by clock core because of lack of users. Handling those clocks is also needed to make it possible to enable support for audio power domain. This patch requires adding sfr0_ctrl clock to device tree.

| | | | | | | | | | | | | | | | | | | | I made a mistake assuming the device tree configuration for interrupt triggering was somehow passed to the SPI device but it's not. In the Motorola Linux kernel tree CPCAP PMIC is configured as a rising edge triggered interrupt, but then then it's interrupt handler keeps looping until the GPIO line goes down. So the CPCAP interrupt is clearly a level interrupt and not an edge interrupt. Earlier when I tried to configure it as level interrupt using the device tree, I did not account that the triggering only gets passed to the SPI core and it also needs to be specified in the CPCAP driver when we do devm_regmap_add_irq_chip().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | MFD support for DA9061 is provided as part of the DA9062 device driver. The registers header file adds two new chip variant IDs defined in DA9061 and DA9062 hardware. The core header file adds new software enumerations for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration for distinguishing between DA9061/62 devices in software. The core source code adds a new .compatible of_device_id entry. This is extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The .data entry now holds a reference to the enumerated device type. A new regmap_irq_chip model is added for DA9061 and this supports the new list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the new sub system components for DA9061. Support is added for a new DA9061 regmap_config which lists the correct readable, writable and volatile ranges for this chip. The probe function uses the device tree compatible string to switch on the da9062_compatible_types and configure the correct mfd cells, irq chip and regmap config. Kconfig is updated to reflect support for DA9061 and DA9062 PMICs. Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Hence reset the MUX to GPIO_7 mode to release the POWERHOLD and the DEV_ON bit to take effect to power off the PMIC. PMIC Power off happens in dire situations like thermal shutdown so irrespective of the POWERHOLD setting go ahead and turn off the powerhold.

Additionally, arizona_poll_reg essentially hard-codes regmap_read_poll_timeout, update the implementation to use regmap_read_poll_timeout. We still keep arizona_poll_reg around as regmap_read_poll_timeout is a macro so rather than expand this for each caller keep it wrapped in arizona_poll_reg. Whilst we are doing this make the timeouts a little more generous as the previous system had a bit more slack as it was done as a delay per iteration of the loop whereas regmap_read_poll_timeout compares ktime's.

| | | | | | | | | | | | | | | | | | | | | This is a sucky change to bump up the time we'll wait for the EC. Why is it sucky? If 200ms for a transfer is a common thing it will have a massively bad impact on keyboard responsiveness. It still seems like a good idea to do this, though, because we have a gas gauge that claims that in an extreme case it could stretch the i2c clock for 144ms. It's not a common case so it shouldn't affect responsiveness, but it can happen. It's much better to have a single slow keyboard response than to start returning errors when we don't have to. In newer EC designs we should probably implement a virtual battery to respond to the kernel to insulate the kernel from these types of issues.

LMU fault monitor ----------------- LM3633 and LM3697 provide hardware monitoring feature. It enables open or short circuit detection. After monitoring is done, each device should be re-initialized. Notifier is used for this case. Separate patch for 'ti-lmu-fault-monitor' will be sent later. Backlight --------- It's handled by TI LMU backlight consolidated driver and chip dependent data. Separate patchset will be sent later. LED indicator ------------- LM3633 has 6 indicator LEDs. Programmable dimming pattern is also supported. Separate patch for 'leds-lm3633' will be sent later. Regulator --------- LM3631 has 5 regulators for the display bias. LM3632 supports 3 regulators. One consolidated driver enables it. The lm363x regulator driver is already upstreamed.

* mfd: axp20x: Add support for dts property "xpowers,master-mode"Rask Ingemann Lambertsen2017-04-271-8/+13
| | | | | | | | | | | | | commit b101829a029a ("mfd: axp20x: Fix AXP806 access errors on cold boot") was intended to fix the case where a board uses an AXP806 in slave mode, but the boot loader leaves it in master mode for lack of AXP806 support. But now the driver breaks on boards where the PMIC is operating in master mode. This patch lets the driver use the new device tree property "xpowers,master-mode" to set the correct operating mode for the board.

| | | | | | | | | | | Since commit 845c877009cf ("i2c / ACPI: Assign IRQ for devices that have GpioInt automatically") I2C core assigns interrupt line to I2C slave devices with regarding to GpioInt() resources.
