  • 216a094de   pwm: Replace HTTP links with HTTPS ones ... Browse Code »

    Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

  • cc37655e6   pwm: pwm-ti*: Remove support for local clock gating ... Browse Code »

    The PWMSS local clock gating registers have no real purpose on OMAP ARM
    devices. These registers were left over registers from DSP IP where the
    PRCM doesn't exist. There is a silicon bug where gating and ungating clocks
    don't function properly. TRMs will be update to indicate that these
    registers shouldn't be touched.

    Therefore, all code that accesses the PWMSS_CLKCONFIG or PWMSS_CLKSTATUS
    will be removed by this patch with zero loss of functionality by the ECAP
    and EPWM drivers.

  • ae5200d22   pwm: pwm-ti*: Get the clock from the PWMSS parent when using old bindings ... Browse Code »

    When using the old eCAP and ePWM bindings for AM335x and AM437x the clock
    can be retrieved from the PWMSS parent. Newer bindings will insure that
    this clock is provided via device tree.

    Therefore, update this driver to support the newer and older bindings. In
    the case of the older binding being used give a warning.

    Some PWM drivers are testing the PWMF_ENABLED flag. Create a helper
    function to hide the logic behind enabled test. This will allow us to
    smoothly move from the current approach to an atomic PWM update
    approach.

    Pull PWM changes from Thierry Reding:
    "A new driver has been added to support the PWM mode of the timer
    counter blocks found on Atmel AT91 SoCs. The VT8500 driver now
    supports changing the PWM signal polarity and the TI drivers (EHRPWM
    and ECAP) gained suspend and resume functionality.

    User drivers can now query the core for whether access to a PWM device
    will sleep (if the PWM chip is on a slow bus such as I2C or SPI).

    The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK
    state in addition to the FB layer's blanking states.

    To round things off, a few fixes and cleanups are also included"

    Make sure the duty-cycle and period passed in are not negative. This
    should eventually be made implicit by making them unsigned. While at
    it, the drivers' .config() implementations can have the equivalent

  • 8e0cb05b3   pwm: pwm-tiecap: PWM driver support for ECAP APWM ... Browse Code »

    ECAP hardware on AM33XX SOC supports auxiliary PWM (APWM) feature. This
    commit adds PWM driver support for ECAP hardware on AM33XX SOC.

    In the ECAP hardware, each PWM pin can also be configured to be in
    capture mode. Current implementation only supports PWM mode of
    operation. Also, hardware supports sync between multiple PWM pins but
    the driver supports simple independent PWM functionality.
