pwm: add devm_pwm_get() and devm_pwm_put()

2012-09-10T15:05:45Z

Add resource managed variants of pwm_get() and pwm_put() for convenience. Code is largely inspired by the equivalent devm functions of the regulator framework. Signed-off-by: Alexandre Courbot Signed-off-by: Thierry Reding

Merge tag 'pinctrl-for-v3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control subsystem changes from Linus Walleij: - Generic Device Tree bindings and hooks for drivers so we can move over modern drivers to using this. - Device Tree bindings for Tegra SoCs. - Funneling some devicetree helper code for the drivers/of subsystem. - New pin control drivers for: * Freescale MXS * Freescale i.MX51 * Freescale i.MX53 All of these use Device Tree bindings. - Dummy pinctrl handles for stepwise migration to pinctrl, akin to dummy regulators. - Minor non-urgent fixes and improvments.

ARM: 7376/1: clkdev: Implement managed clk_get()

2012-04-19T18:34:18Z

Allow clk API users to simplify their cleanup paths by providing a managed version of clk_get() and clk_put(). Signed-off-by: Mark Brown Signed-off-by: Russell King

pinctrl: implement devm_pinctrl_get()/put()

2012-04-18T11:53:13Z

These functions allow the driver core to automatically clean up any allocations made by drivers, thus leading to simplified drivers. Signed-off-by: Stephen Warren Signed-off-by: Linus Walleij

regulator: Add devm_regulator_get()

2012-01-20T12:02:55Z

Add a resource managed regulator_get() to simplify regulator usage in drivers. This allows driver authors to "get and forget" about their regulators by automatically calling regulator_put() when the driver is detached.

lib: devres: add convenience function to remap a resource

2011-11-16T00:07:39Z

Almost every platform_driver does the three steps get_resource, request_mem_region, ioremap. This does not only lead to a lot of code duplication, but also a huge number of similar error strings and inconsistent error codes on failure. So, introduce a helper function which simplifies remapping a resource and make it hard to do something wrong and add documentation for it.

docs/driver-model: Update device class docs

2011-08-24T23:01:24Z

The driver model documentation was added to the kernel tree before struct class was added to . Hence this patch that updates the paragraph about struct class in Documentation/driver-model/binding.txt. Signed-off-by: Bart Van Assche Cc: Randy Dunlap Signed-off-by: Greg Kroah-Hartman
