The TWL4030 IRQ handler has a bug which leads to spinlock lock-up. It is
calling the 'unmask' function in a process context. :The mask/unmask/ack
functions are only designed to be called from the IRQ handler code,
or the proper API interfaces found in linux/interrupt.h.Also there is no need to have IRQ chaining mechanism. The right way to
handle this is to claim the parent interrupt as a standard interrupt
and arrange for handle_twl4030_pih to take care of the rest of the devices.Mail thread on this issue can be found at:

The keypad driver for the DM355 EVM got slightly broken as it merged,
since it moved from input/keyboard to input/misc and its Kconfig

Since ASIC3 has to work on both PXA and S3C and since their
struct clk implementations differ, we can't register out

For now we have to keep clock handling internal to this

mfd_cell->enable/disable functions.Signed-off-by: Philipp Zabel

The PCAP Asic as present on EZX phones is a multi function device with
voltage regulators, ADC, touch screen controller, RTC, USB transceiver,
leds controller, and audio codec.It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).Signed-off-by: Daniel Ribeiro

found in the ST-Ericsson U300 series platforms. This driver
is a singleton proxy for all accesses to the AB3100

regulators, battery and system power control, vibrator,
LEDs, and an ALSA codec.Signed-off-by: Linus Walleij

The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons. After more than two years it's
time to remove them finally.This patch cleans up one of the remaining users. When all such patches
hit mainline we can remove the defines and typedefs finally.Impact: cleanup
Convert the last remaining users and remove the typedef.

Impact: Fix section mismatch.
clocks_init() has been called from twl4030_probe() which is a non-init
function. Since probing can be done anytime so clocks_init will be
called anytime too. So we mark clock_init() as non-init.LD drivers/mfd/built-in.o
WARNING: drivers/mfd/built-in.o(.text+0x8dd9): Section mismatch in
reference from the function twl4030_probe() to the function
.init.text:clocks_init()
The function twl4030_probe() references
the function __init clocks_init().
This is often because twl4030_probe lacks a __init
annotation or the annotation of clocks_init is wrong.Signed-off-by: Rakib Mullick

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.Cc: Samuel Ortiz

Due to the way that the WM8350 audio driver handles CODEC_ENA many of
the WM8350 audio registers are marked as volatile when they aren't
actually so. Allow the audio driver to see a cache of these values for
inspection during interrupt context.To do this we need to stop satisfying any bits from volatile registers
from cache - there's no real benefit from doing so anyway, we did the
read already.Signed-off-by: Mark Brown

Some I2C controllers have high overheads for setting up I2C operations

need later.Signed-off-by: Mark Brown
