mfd: Only unregister platform devices allocated by the mfd core

2013-01-17T16:45:58+00:00

commit b9fbb62eb61452d728c39b2e5020739c575aac53 upstream.

mfd_remove_devices would iterate over all devices sharing a parent with
an mfd device regardless of whether they were allocated by the mfd core
or not. This especially caused problems when the device structure was
not contained within a platform_device, because to_platform_device is
used on each device pointer.

This patch defines a device_type for mfd devices and checks this is
present from mfd_remove_devices_fn before processing the device.

mfd: twl4030: Fix chained irq handling on resume from suspend

2012-11-21T16:46:41+00:00

The irqs are enabled one-by-one in pm core resume_noirq phase.
This leads to situation where the twl4030 primary interrupt
handler (PIH) is enabled before the chained secondary handlers
(SIH). As the PIH cannot clear the pending interrupt, and
SIHs have not been enabled yet, a flood of interrupts hangs
the device.

Fixed the issue by setting the SIH irqs with IRQF_EARLY_RESUME
flags, so they get enabled before the PIH.

mfd: arizona: Sync regcache after reset

2012-11-20T11:46:45+00:00

In the absence of a physical reset line the chip is reset by writing the
first register, which is done after the register patch has been applied.
This patch synchronises the register cache after the reset to preserve
any register changes that had been applied.

mfd: arizona: Correctly report when AIF2/AIF1 is underclocked

2012-11-20T11:46:45+00:00

In the interrupt handler for an underclocked event, whilst checking for
the source of the interrupt, AIF3 was checked twice and AIF1 was not
checked. This change correctly checks the AIF1 underclocked bit and
reports the correct error messages for all cases.

mfd: arizona: Use correct array for ARRAY_SIZE in mfd_add_devices call

2012-11-20T11:46:45+00:00

wm5102_devs array was used for ARRAY_SIZE whilst adding the wm5110
devices. This change corrects this to get the size from the wm5110_devs
array. As both arrays are the same size no issues should have been
caused by this bug.

mfd: twl-core: Fix chip ID for the twl6030-pwm module

2012-11-20T11:35:16+00:00

The correct chip id is 1 since the PWM module is on address 0x49. With the
current TWL6030_MODULE_ID1 the kernel will crash early since we have:

 #define TWL6030_MODULE_ID1 0x0E
and
 static struct twl_client twl_modules[4];

Down in the stack we try to get the module by:
struct twl_client	*twl = &twl_modules[chip];

Which is obviously going to do nasty things.

Pull battery updates from Anton Vorontsov:
 "1. New drivers:
     - Marvell 88pm860x charger and battery drivers;
     - Texas Instruments LP8788 charger driver;
  2. Two new power supply properties: whether a battery is authentic,
     and chargers' maximal currents and voltages;
  3. A lot of TI LP8727 Charger cleanups;
  4. New features for Charger Manager, mainly now we can disable
     specific regulators;
  5. Random fixes and cleanups for other drivers."
