One of my programs frequently grabs the parport, does something with it
and then drops it again. This results in spamming of the kernel log with"... registered pardevice"
"... unregistered pardevice"These messages are completely useless, except for debugging ppdev,
probably. So put them under DEBUG (or dynamic debug).Signed-off-by: Michael Buesch

memory_open() ignores devlist and does a switch for each item, duplicating
code and conditional definitions.Clean it up by adding backing_dev_info to devlist and use it to lookup for
the minor device.[akpm@linux-foundation.org: coding-style fixes]

On OpenFirmware platforms, it makes the most sense to get platform_data
from the device tree. Make an attempt to translate OF node properties
into platform_data struct before bailing out.Note that the implementation approach taken differs from other device
drivers that make use of device tree information. This is because I2C
chips are already registered automatically by of_i2c, so we can get by
with a small translator function in the driver.[akpm@linux-foundation.org: coding-style fixes]

Add support for the Epson RX-8025SA/NB RTC chips. It includes support for
alarms, periodic interrupts (1 Hz) and clock precision adjustment.For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets
created in "/sys/class/rtc/rtcX/device". It permits to set and get the
clock adjustment in ppb (parts per billion), e.g.:# echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb
# cat /sys/class/rtc/rtc0/device/clock_adjust_ppb
-183000This allows to compensate temperature dependent clock drifts. According
to the RX8025 SA/NB application manual the frequency and temperature
characteristics can be approximated using the following equation:df = a * (ut - t)**2
df: Frequency deviation in any temperature
a : Coefficient = (-35 +-5) * 10**-9
ut: Ultimate temperature in degree = +25 +-5 degree
t : Any temperature in degreeSigned-off-by: Wolfgang Grandegger

The RTC driver for ds1742 / ds1743 uses a static nvram attribute. This
patch replaces this static attribute with one nvram attribute for each
ds174x registered.The nvram size is not the same for all types of ds174x. The nvram size is
accessible as the file size of the nvram attribute in sysfs. With only a
single nvram attribute, this file size will be incorrect if more than one
type of ds174x is present on a system. See the comment in the removed
code below.This patch have been tested with linux-2.6.28 and linux-2.6.29-rc5/6 on a
custom board with one ds1743.Signed-off-by: Torsten Ertbjerg Rasmussen

Move some common spi_setup() error checks into the SPI framework from the
spi_master controller drivers:- Add a new "mode_bits" field to spi_master
- Use that in spi_setup to validate the spi->mode value being
requested. Setting this new field is now mandatory for any
controller supporting more than vanilla SPI_MODE_0.- Update all spi_master drivers to:
* Initialize that field
* Remove current spi_setup() checks using that value.This is a net minor code shrink.

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

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
