commit 59ee93a528b94ef4e81a08db252b0326feff171f upstream.
The irq_to_gpio function was removed from the pxa platform
in linux-3.2, and this driver has been broken since.
There is actually no in-tree user of this driver that adds
this platform device, but the driver can and does get enabled
on some platforms.
Without this patch, building ezx_defconfig results in:
drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work':
drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration]

commit c5857ccf293968348e5eb4ebedc68074de3dcda6 upstream.
With the new interrupt sampling system, we are no longer using the
timer_rand_state structure in the irq descriptor, so we can stop
initializing it now.
[ Merged in fixes from Sedat to find some last missing references to
rand_initialize_irq() ]

commit 775f4b297b780601e61787b766f306ed3e1d23eb upstream.
We've been moving away from add_interrupt_randomness() for various
reasons: it's too expensive to do on every interrupt, and flooding the
CPU with interrupts could theoretically cause bogus floods of entropy
from a somewhat externally controllable source.
This solves both problems by limiting the actual randomness addition
to just once a second or after 64 interrupts, whicever comes first.
During that time, the interrupt cycle data is buffered up in a per-cpu
pool. Also, we make sure the the nonblocking pool used by urandom is
initialized before we start feeding the normal input pool. This
assures that /dev/urandom is returning unpredictable data as soon as
possible.
(Based on an original patch by Linus, but significantly modified by
tytso.)

commit 3f8349e6e98ba0455437724589072523865eae5e upstream.
TWL6030 family of PMIC use a shadow interrupt status register
while kernel processes the current interrupt event.
However, any write(0 or 1) to register INT_STS_A, INT_STS_B or
INT_STS_C clears all 3 interrupt status registers.
Since clear of the interrupt is done on 32k clk, depending on I2C
bus speed, we could in-adverently clear the status of a interrupt
status pending on shadow register in the current implementation.
This is due to the fact that multi-byte i2c write operation into
three seperate status register could result in multiple load
and clear of status and result in lost interrupts.
Instead, doing a single byte write to INT_STS_A register with 0x0
will clear all three interrupt status registers without the related
risk.

This sleep should not be required on normal circuitry provided the
pull-ups on the bus are correctly adapted to the slaves. Unfortunately,
this is not always the case. The sleep is restored but as a parameter to
the probe function in the pdata.

With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

TPS65911 adds new interrupt sources, as well as two new registers
to handle them, one for interrupt status and one for interrupt
masking. The added irqs are:
-VMBCH2 - Low and High threshold
-GPIO1-8 - Rising and falling edge detection
-WTCHDG - Watchdog interrupt
-PWRDN - PWRDN reset interrupt
The code should handle these new registers only when the chip
version is TPS65911.

The TPS65911 is the next generation of the TPS65910 family of
PMIC chips. It adds a few features:
- Watchdog Timer
- PWM & LED generators
- Comparators for system control status
It also adds a set of Interrupts and GPIOs, among other things.
The driver exports a function to identify between different
versions of the tps65910 family, allowing other modules to
identify the capabilities of the current chip.

Following patch should fix the dependency problems. Please review:
From: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk>
[PATCH] MFD: TPS65910: Fix I2C dependency
TPS65910 driver can only be compiled built-in, so the I2C driver
should be as well.

The following patch should solve this:
From: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk>
MFD: Fix TPS65910 build
Support for tps65910 as a module is not available. The driver can
only be compiled as built-in. OTOH, the regulator driver can still
be built as module without breaking the compilation.

This module controls the interrupt handling for the tps chip. The
interrupt sources are the following:
- GPIO falling/rising edge detection
- Battery voltage below/above threshold
- PWRON signal
- PWRHOLD signal
- Temperature detection
- RTC alarm and periodic event

The TPS65910 chip is a power management IC for multimedia and handheld
devices. It contains the following components:
- Regulators
- GPIO controller
- RTC
The tps65910 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.

The usbhs core driver does not enable/disable the interface and
functional clocks; These clocks are handled by hwmod and runtime pm,
hence insted of the clock enable/disable, the runtime pm APIS are
used. however,the port clocks and tll clocks are handled
by the usbhs core.

1. Return proper error if omap_usbhs_alloc_child fails
2. In the case of goto err_ehci, we should call platform_device_unregister(ehci)
instead of platform_device_put(ehci) because we have already added the
platform device to device hierarchy.

The charger fault IRQs from the twl will in future patches be handled
by a seperate IRQ handler in the charger driver than the general charger
IRQ. Give them different IRQ numbers now to allow the charger driver to

Phoenix Lite is based on the twl6030 family of PMICs. It has mostly the
same feature set of twl6030 but with small changes. The codec block has
also been removed. It also has a new charger block and new features in
its ADC block. VUSB handling also differs.
