From the datasheet, the actual duty cycle is:
(period - (1 / clk) * CDTY) / period
This actually correct the polarity of the PWM and solves the issue that
pwm-leds exhibits: when setting a duty cycle of 0 and then disabling a
channel, the level was wrong (1 when the polarity was normal and 0 when
the polarity was inversed).

When atmel_pwm_config() calculates and then sets the prescaler, it is
overwriting the channel's CMR register so we are losing the CPOL
configuration.
As atmel_pwm_config() is always called before enabling a channel,
inverting the polarity doesn't work.
Fix that by reading CMR first and only overwriting the prescaler bits.

This is the other of the LP3943 MFD driver.
LP3943 can be used as a PWM generator, up to 2 channels.
* Two PWM generators supported
* Supported PWM operations
request, free, config, enable and disable
* Pin assignment
A driver data, 'pin_used' is checked when a PWM is requested.
If the output pin is already assigned, then returns as failure.
If the pin is available, 'pin_used' is set.
When the PWM is not used anymore, then it is cleared.
It is defined as unsigned long type for atomic bit operation APIs,
but only LSB 16bits are used because LP3943 has 16 outputs.

This patch adds device tree support to the PXA's PWM driver. Nothing
needs to be extracted from the device tree node by the PWM device.
Client devices need only specify the period; the per-chip index is
implicitly zero because one device node must be present for each PWM
output in use. This approach is more convenient due to the wide
variability in the number of PWM channels present across the various PXA
variants, and is made possible by the fact that the register sets for
each PWM channel are segregated from each other. An of_xlate() method
is added to parse this single-cell node. The existing ID table is
reused for the match table data.
Tested on a Palm Treo 680 (both platform data and DT cases).

Commit 76abbdde2d95a3807d0dc6bf9f84d03d0dbd4f3d
pwm: Add sysfs interface
causes a kernel oops due to a null pointer dereference on PXA platforms.
This happens because the class added by the patch is registered in a
subsys_initcall (initcall4), but the pxa pwm driver is registered in
arch_initcall (initcall3). If the class is not registered before the
driver probe function runs, the oops occurs in device_add() when the
uninitialized pointers in struct class are dereferenced. I don't see a
reason that the driver must be an arch_initcall, so this patch makes it
a regular module_platform_driver (initcall6), preventing the oops.
