* mfd: smsc-ece1099: Make it explicitly non-modularPaul Gortmaker2016-10-041-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_SMSC drivers/mfd/Kconfig: bool "SMSC ECE1099 series chips" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. We replace module.h with init.h and delete an unused moduleparam.h include. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

* mfd: as3722: Convert MFD_AS3722 from bool to tristatePaul Gortmaker2016-10-041-1/+1

In response to an earlier patch set suggesting removal of the unused modular code, Laxman suggested that this driver be instead moved to tristate. We do that here, and confirm it can build and modpost as a tristate. However there remains to be runtime testing in order to ensure this change is 100% functional for "=m".

* mfd: ucb1x00: Remove NO_IRQ checkArnd Bergmann2016-10-041-1/+1
| | | | | | | | | | | | | | probe_irq_off() returns '0' on failure, not NO_IRQ, so the check in this driver is clearly wrong. This replaces it with the regular '!irq' check used in other drivers. The sa1100 platform that this driver is used on originally numbered all its interrupts starting at '0', which would have conflicted with this change, but as of commit 18f3aec ("ARM: 8230/1: sa1100: shift IRQs by one"), this is not a problem any more.

* mfd: arizona: Use suspend_noirq inplace of suspend_lateCharles Keepax2016-10-041-6/+4
| | | | | | | | | | | | | | | | | | | As runtime PM doesn't function whilst processing system suspend/resume operations and the Arizona IRQ handlers need runtime PM to function we must disable IRQs during these operations. Whilst this is already done in the driver we are using suspend/suspend_late and resume/resume_noirq to do so which has two problems. Firstly, as suspend_late is before suspend_noirq that means we still have a small window where an IRQ can cause issues. Secondly, if another suspend_late handler fails after ours has run then (as resume_noirq will not run) we will make unbalanced calls to enable_irq. This is all simply fixed by using the suspend_noirq callback rather than suspend_late. Whilst we are doing this tidy the code up a little, and use the appropriate helper macros.

* mfd: arizona: Add sensible return value to some error pathsCharles Keepax2016-10-041-1/+4
| | | | | | | | | | | | | | | There are some cases in arizona_dev_init, such as where we don't recognise the chip ID, in which we head to the error path without setting a sensible error code in ret. This would lead to the chip silently failing probe, as it would still return 0. Fix this up by adding appropriate sets of the return value. Whilst adding these update the existing paths that do return an error when the chip is not recognised to use ENODEV, which seems like a better fit.

Clearance of any the persistent information within the DA9053 FAULT_LOG register must be completed during start-up so the fault-log does not continue with previous values.

| | | | | | | | | | | | | | | | | Member "status" of struct usb_sg_request is managed by usb core. A spin lock is used to serialize the change of it. The driver could check the value of req->status, but should avoid changing it without the hold of the spinlock. Otherwise, it could cause race or error in usb core.

* mfd: qcom_rpm: Handle message RAM clockLinus Walleij2016-10-041-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSM8660, APQ8060, IPQ806x and MSM8960 have a GCC clock to the message RAM used by the RPM. This needs to be enabled for messages to pass through. This is a crude solution that simply prepare/enable at probe() and disable/unprepare at remove(). More elaborate PM is probably possible to add later. The construction uses IS_ERR() to gracefully handle the platforms that do not provide a message RAM clock. It will bail out of probe only if the clock is hitting a probe deferral situation. Of course this requires the proper device tree set-up: rpm: rpm@104000 { compatible = "qcom,rpm-msm8660"; clocks = <&gcc RPM_MSG_RAM_H_CLK>; clock-names = "ram"; ... }; I have provided this in the MSM8660 device tree, and will provide patches for the other targets.

It's a temporary change until the CODEC's clock controller gets exposed through the clk API and is helpful for board configurations where the MCLK clocks are not provided by always on oscillators.

This PMIC has a new register layout, and supports some functions not seen in other X-Powers PMICs, such as master-slave mode, or having multiple AXP806 PMICs on the same bus with address space extension, or supporting both I2C and RSB mode. I2C has not been tested. This patch adds support for the interrupts of the PMIC. A regulator sub-device is enabled, but actual regulator support will come in a later patch.
