pwm: spear: Fix checking return value of clk_enable() and clk_prepare()

2013-05-11T20:53:50+00:00

commit 563861cd633ae52932843477bb6ca3f1c9e2f78b upstream.

The logic to check return value of clk_enable() and clk_prepare() is reversed,
fix it.

Pull pwm changes from Thierry Reding:
 "A new driver has been added for the SPEAr platform and the
  TWL4030/6030 driver has been replaced by two drivers that control the
  regular PWMs and the PWM driven LEDs provided by the chips.

  The vt8500, tiecap, tiehrpwm, i.MX, LPC32xx and Samsung drivers have
  all been improved and the device tree bindings now support the PWM
  signal polarity."

Fix up trivial conflicts due to __devinit/exit removal.

pwm: samsung: add missing s3c->pwm_id assignment

2012-12-14T07:32:58+00:00

The s3c->pwm_id is used to calculate offset of related register.

pwm: lpc32xx: Set the chip base for dynamic allocation

2012-12-06T07:52:13+00:00

Doing so allows the base to be allocated dynamically at runtime and
makes it easier for the chip to coexist with other PWM chips.

pwm: lpc32xx: Properly disable the clock on device removal

2012-12-06T07:52:11+00:00

A single clock is used for all PWMs meaning the clock's reference count
might be between 0 and N when .remove() is called. Instead of a single
clk_disable() call pwm_disable() on each PWM, to ensure that
clk_disable() is called for each PWM that is still enabled.

pwm: lpc32xx: Fix the PWM polarity

2012-12-06T07:52:07+00:00

The duty cycles value goes from 1 (99% HIGH) to 256 (0% HIGH) but it
is stored modulo 256 in the register as it is only 8 bits wide.

pwm: i.MX: eliminate build warning

2012-12-06T07:52:04+00:00

compiling the i.MX pwm driver produces the following warning:
|drivers/pwm/pwm-imx.c: In function 'imx_pwm_probe':
|drivers/pwm/pwm-imx.c:281:7: warning: assignment discards qualifiers from pointer target type

Apply a 'const' attribute to the affected variable declaration.

pwm: Export of_pwm_xlate_with_flags()

2012-12-06T07:51:38+00:00

Drivers may want to use this function if they support any of the flags
that can be passed via a third cell in the DT specifier. Since those
drivers may be built as modules the symbol needs to be exported to make
sure that it can be accessed.
