Add support for handling IRQs: power button, AC and USB power state changes. Mask and interrupt bits are shared within one register, which prevents us to use regmap_irq implementation. New irq_domain is created in order to add interrupt handling for each tps65217's subsystem. IRQ resources have been added for charger subsystem to be able to notify about AC and USB state changes.

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 18f3aec3 ("ARM: 8230/1: sa1100: shift IRQs by one"), this is not a problem any more.

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. Signed-off-by:

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. Signed-off-by:

This patch adds common driver for the Top block of the Samsung Exynos SoC Low Power Audio Subsystem. This is a minimal driver which prepares resources for IP blocks like I2S, audio DMA and UART and exposes a regmap for the Top block registers. Also system power ops are added to ensure the Audio Subsystem is operational after system suspend/resume cycle. Signed-off-by:

The function da9052_clear_fault_log() is added to mitigate the case of persistent data being transferred between reboots. 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. A clearance function has been added here in the kernel driver because wiping the fault-log cannot be counted on outside the Linux kernel. Signed-off-by:

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. This patch could be backported to stable kernels with version later than v3.14.

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.

The X-Powers AXP806 is a new PMIC that is paired with Allwinner's A80 SoC, along with a master AXP809 PMIC. 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. Signed-off-by:
