    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    TWL4030/6030 driver has been replaced by two drivers that control the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.

  • 983290b06   pwm: i.MX: eliminate build warning ... Browse Code »

    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.

  • 7b27c160c   pwm: i.MX: fix clock lookup ... Browse Code »

    The i.MX PWM core has two clocks: The ipg clock and the ipg highfreq
    (peripheral) clock. The ipg clock has to be enabled for this hardware
    to work. The actual PWM output can either be driven by the ipg clock
    or the ipg highfreq. The ipg highfreq has the advantage that it runs
    even when the SoC is in low power modes.
    This patch requests both clocks and enables the ipg clock for accessing
    registers and the peripheral clock to actually turn on the PWM.

    The i.MX PWM module has two clocks: The ipg clock and the ipg highfreq
    (peripheral) clock. The ipg clock has to be enabled for this hardware
    to work. The actual PWM output can either be driven by the ipg clock
    or the ipg highfreq. The ipg highfreq has the advantage that it runs

    Use the always running clock also on i.MX25.

    At the same time remove platform based support. No user for
    this driver has made it into mainline so far, so all we break
    is out of tree stuff.

  • 66ad6a613   pwm: i.MX: add functions to enable/disable pwm. ... Browse Code »

    We used to enable/disable the PWM only by switching the
    clock on or off. Instead, use the dedicated register bits.
    These differ on different SoCs, so introduce a SoC specific
    function for this.

    The PWM core makes sure that pwm_enable/disable are called only
    once. Still keep the enabled state since we will need it in
    pwm_config.
