• 5c31252c4   pwm: Add the pwm_is_enabled() helper ... Browse Code »

  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.

  A platform_driver does not need to set an owner, it will be populated by the
  driver core.

  The struct is not used anymore and the polarity initialization will be
  done using the PWM lookup table (or device tree).

  The site-specific OOM messages are unnecessary, because they
  duplicate the MM subsystem generic OOM message.

• 88d5a2e6f   pwm: simplify use of devm_ioremap_resource ... Browse Code »

  Remove unneeded error handling on the result of a call to
  platform_get_resource when the value is passed to devm_ioremap_resource.

  Move the call to platform_get_resource adjacent to the call to
  devm_ioremap_resource to make the connection between them more clear.

  A simplified version of the semantic patch that makes this change is as
  follows: (http://coccinelle.lip6.fr/)

  //
  @@
  expression pdev,res,n,e,e1;
  expression ret != 0;
  identifier l;
  @@

  - res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
  - if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
  + res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
  //

  In case of error, the function devm_ioremap_resource() returns ERR_PTR()
  and never returns NULL. The NULL test in the return value check should
  be replaced with IS_ERR().

• 99b82abb0   pwm: Add Renesas TPU PWM driver ... Browse Code »

  The Timer Pulse Unit (TPU) is a 4-channels 16-bit timer used to generate
  waveforms. This driver exposes PWM functions through the PWM API for
  other drivers to use.

  The code is loosely based on the leds-renesas-tpu driver by Magnus Damm
  and the TPU PWM driver shipped in the Armadillo EVA 800 kernel sources.
