This driver is a general version for LM642 led chip of TI.
LM3642 :
The LM3642 is a 4MHz fixed-frequency synchronous boost
converter plus 1.5A constant current driver for a high-current
white LED.
The LM3642 is controlled via an I2C-compatible interface.

Hello,
This series will switch the OMAP audio to use dmaengine.
The final patch which does the switch was based on Russell King's earlier patch.

- sDMA FRAME sync mode is removed and replaced with PACKET

This is necessary to reference the PWM in board device trees.

Some device drivers (panel backlights especially) need to follow precise
sequences for powering on and off, involving gpios, regulators, PWMs
with a precise powering order and delays to respect between each steps.
These sequences are board-specific, and do not belong to a particular
driver -
Make use of the power sequences specified in the device tree or platform
data to control how the backlight is powered on and off.

New revision of the power sequences, taking as usual the feedback that was
kindly provided about the last version.
I think now is a good time to discuss integrating this and to start looking for
a maintainer who would be willing to merge this into his/her tree (I am

The respective values are evaluated at each read/write, so no further
action is required than to change the perm argument to module_param.
Note there is no sanity check so root can make the driver effectively
unusable but that's what root is for :-)

The output of 'git describe' is relative to the immediate preceding tag.
When the immediate tag preceding or at the HEAD is a private tag,
setlocalversion extracts information with respect to the private tag and
wrongly reports them with respect to Linux tag.
