2016-07-12mfd: db8500 stop passing around platform dataArnd Bergmann
Except for the constant DB8500_PRCMU_FW_VERSION_OFFSET number, nothing is ever passed through the platform data and used in a driver, so we can simply stop passing it around.

2015-12-04mfd: ab8500: Delete static IRQ resourcesLinus Walleij

2015-08-11mfd: Kill off set_irq_flags usageRob Herring
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

The AD8500 defines itself as interrupt-controller in DT, but it doesn't assign DT node to IRQ domain when creates it. As result, of_irq_xx() helpers don't work because they can't find necessary IRQ domain. Hence, fix it by assigning AD8500 core device DT node to IRQ domain when it's created.

Get rid of all the static assignments everywhere, delete it from the driver, platform data and the board files in one swift strike.

2013-05-17mfd: ab8500-core: Pass GPADC compatible string to MFD coreLee Jones
When booting with Device Tree enabled the MFD core uses each device's compatible string to find and allocate its associated of_node pointer, which in turn is passed to the driver via the platform_device struct. Without it, the driver won't be able to interrogate the Device Tree or locate suitable regulators and will most likely fail to probe.

2013-05-17mfd: ab8500-core: Use the correct driver name when enabling gpio/pinctrlLee Jones
When we're using Device Tree to enable GPIO drivers we're forced to be OS agnostic, thus we are forbidden use names like pinctrl as they are specific only to Linux, at least for the time being. However, when we are registering devices using internal systems such as MFD or platform registration, we can use such terminology. In this case we can and should use the platform device ID mechanism to specify which device we wish to utilise by detailing pinctrl-<device_name>. This patch fixes a regression that when booting with Device Tree enabled the ABx500 GPIO/Pinctrl devices are not probed.

2013-05-17mfd: ab8500: Pass AB8500 IRQ to debugfs code by resourceLinus Walleij
The AB8500 debug code which was merged in parallell with the multiplatform work incidentally introduced a new instance using the <mach/irqs.h> header which is now deleted, causing this build regression: drivers/mfd/ab8500-debugfs.c:95:23: fatal error: mach/irqs.h: No such file or directory compilation terminated. make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1 The code most certainly never worked with device tree either since that does not rely on this kind of hard-coded interrupt numbers.

We are using a generic abx500 hwmon layer, so rename specific ab8500 to generic abx500 for hwmon device and driver matching. Signed-off-by: Hongbo Zhang <hongbo.zhang@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-02-08mfd: ab8500: allow AB9540 based devices to use ABX500 pinctrlLee Jones
The old AB8500 GPIO driver has been un-BROKEN and converted into a multi-platform pinctrl driver. If any AB9540 based devices wish to request any GPIO pins that it offers, they can after this patch.

2013-02-08mfd: ab8500: ensure new AB8500 pinctrl driver is probed correctlyLee Jones
The old, BROKEN AB8500 GPIO driver has been revamped as a shiny new pinctrl driver and has been renamed as such. So, if we would like to make use of it, we need to register it via its new name.

2013-02-08mfd: ab8500: provide a irq_set_type() functionLee Jones
In the AB8500 IRQ mask and unmask functions, we rely on testing for IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to physically mask and unmask the correct interrupt lines. In order for us to do that, the trigger needs to be set in the associated flags. However, unless a irq_set_type() function pointer is passed when registering the IRQ chip, the IRQ subsystem will refuse to do it. For that reason, we're providing one.

2013-02-08mfd: ab8500: actually handle the AB8500 GPIO IRQs correctlyLinus Walleij
The patch: "mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly" altered the AB8500 IRQ mask/unmask functions such that they would handle masking on/off the falling edge IRQ if this was requested by the consumer. However the bit mask for hwirqs 43 and 44 was shifting the bit mask incorrectly, resulting in the wrong IRQ being mased/unmasked. Further while the patch would mask/unmask the correct line, when the interrupt actually came in, it would still be treated as a valid hwirq. The offsetting applied when masking/unmasking was not applied when handling the IRQ, i.e. the falling edge lines were not routed back to the rising edge lines. This fixes both cases. The end result has been tested with the SIM detect IRQ, GPIO12, hwirq 46 and 62.

2013-02-08mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctlyLee Jones
In an upcoming patch, the gpio-ab8500 driver will relinquish all IRQ handling capability and pass it back into the AB8500 core driver. This will aid in reducing massive code duplication within the kernel. Also, most of the functionality is already in the AB8500 core driver, as the GPIO IRQs are actually sandwiched between lots of other IRQs which the core driver already handles. All we're doing here is providing the core driver with knowledge that each GPIO has two IRQs assigned to it; one for rising and a separate one for falling.

2013-01-23u8500-charger: Delay for USB enumerationPaer-Olof Haakansson
If charging is started before USB enumeration of an Accessory Charger Adapter has finished, the AB8500 will generate a VBUS_ERROR. This in turn results in timeouts and delays the enumeration with around 15 seconds. This patch delays the charging and then ramps currents slowly to avoid VBUS errors. The delay allows the enumeration to have finished before charging is turned on.

Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.
