ASoC: TWL6040: Add twl6040 codec driver

Initial version of TWL6040 codec driver.

The TWL6040 codec uses a proprietary PDM-based digital audio interface.
Audio paths supported are:

- Input: Main Mic, Sub Mic, Headset Mic, Auxiliary-FM Left/Right
- Output: Headset Left/Right, Handsfree Left/Right

TWL6040 codec supports power-up/down manual and automatic sequence.
Manual sequence is done through a specific register writes sequence.
Automatic sequence is done when the codec is powered-up through the
external AUDPWRON line. The completion of the sequence is signaled
through the audio interrupt.

TWL6040 codec sysclk can be provided by: low-power or high
performance PLL:

- The low-power PLL takes a low-frequency input at 32,768 Hz and
generates an approximate of 17.64 or 19.2 MHz (for 44.1 KHz and 48 KHz
respectively)

- The high-performance PLL generates an exact 19.2 MHz clock signal
from high-frequency input at 12/19.2/26/38.4 MHz.

Low-power playback mode is a special scenario where only headset path
(headset DAC and driver) is active.

For the particular case of headset path, PLL being used defines the
headset power mode: low-power, high-performance.

ASoC: PCM_RATE: Check for KNOT and CONTINUOUS flags

For ASoC, if either CPU or CODEC driver has set the flag, the MACHINE driver
should be given a chance to figure out if the dai, that set the flag, can
accomodate a rate that it does not explicitly specify but is specified
by the dai at the other end of the link.

14 years agosysfs: Serialize updates to the vfs inode
Eric W. Biederman [Sat, 13 Feb 2010 03:22:23 +0000 (19:22 -0800)]
sysfs: Serialize updates to the vfs inode

The vfs depends upon filesystem methods to update the
vfs inode.   Sysfs adds to the normal number of places
where the vfs inode is updated by also updatng the
vfs inode in sysfs_refresh_inode.

Typically the inode mutex is used to serialize updates
to the vfs inode, but grabbing the inode mutex in
sysfs_permission and sysfs_getattr causes deadlocks,
because sometimes the vfs calls those operations with
the inode mutex held.  Therefore sysfs  can not use the
inode mutex to serial updates to the vfs inode.

The sysfs_mutex is acquired in all of the routines
where sysfs updates the vfs inode, and with a small
change we can consistently protext sysfs vfs inode
updates with the sysfs_mutex. To protect the sysfs
vfs inode updates with the sysfs_mutex simply requires
extending the scope of sysfs_mutex in sysfs_setattr
over inode_setattr, and over inode_change_ok (so we
have an unchanging inode when we perform the check).

UIO: Remove SMX Cryptengine driver

Ben Nizette, the author of this driver, told me in a private mail that this
project has been cancelled. He suggested to remove the driver for now, and
will come back with a new version should the hardware really exist.
This patch completely removes the driver.

UIO: minor Kconfig fixes

Two trivial fixes for the Userspace IO Kconfig file:
1) uio_sercos3 is a PCI driver, so let it depend on PCI.
2) "default n" under UIO_PCI_GENERIC is luxury since it is already the default.

UIO: Add a driver for Hilscher netX-based fieldbus cards

This patch adds a Userspace IO driver for netX-based fieldbus cards by
Hilscher (see http://www.hilscher.com). ATM, cifX and comX cards are
supported. The userspace part for this driver is provided by Hilscher
and should come with the card.
The driver is in use for several months now and has been tested by
people at Hilscher and Linutronix.

auxdisplay: move cfag12864bfb's probe function to .devinit.text

A pointer to cfag12864bfb_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
