* misc: atmel_pwm: only build for supported platformsArnd Bergmann2014-05-271-1/+2
| | | | | | | | | | | | | | | | | | There is architecture code in mach-at91 that depends on the CONFIG_ATMEL_PWM symbol in order to call the soc-specific at91_add_device_pwm function. While all of this is about code that will be removed in the future, using DT probing and the PWM framework, we currently get a build failure: arch/arm/mach-at91/built-in.o: In function `at91_pwm_leds': arch/arm/mach-at91/leds.c:88: undefined reference to `at91_add_device_pwm' This patch ensures we only try to build this driver on platforms on which it will build and work.

| | | | | | | | | | | | | When platform_get_irq() is failed after "priv" allocated, it need to free "priv". But the label of bad0 doesn't try to free about "priv". So this patch changes that lable to "bad1". But "bad1" has pm_runtime_disable() call, this function should be called when uio_register_device() is failed.

* w1: optional bundling of netlink kernel repliesDavid Fries2014-05-276-263/+447
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Applications can submit a set of commands in one packet to the kernel, and in some cases it is required such as reading the temperature sensor results. This adds an option W1_CN_BUNDLE to the flags of cn_msg to request the kernel to reply in one packet for efficiency. The cn_msg flags now check for unknown flag values and return an error if one is seen. See "Proper handling of unknown flags in system calls" http://lwn.net/Articles/588444/ This corrects the ack values returned as per the protocol standard, namely the original ack for status messages and seq + 1 for all others such as the data returned from a read. Some of the common variable names have been standardized as follows. struct cn_msg *cn struct w1_netlink_msg *msg struct w1_netlink_cmd *cmd struct w1_master *dev When an argument and a function scope variable would collide, add req_ to the argument.

* connector: allow multiple messages to be sent in one packetDavid Fries2014-05-273-5/+26

For the one wire use there can be multiple struct w1_netlink_cmd in a struct w1_netlink_msg and multiple of those in struct cn_msg, and with this change multiple of those in a struct nlmsghdr, and at each level the len identifies there being multiple of the next.

Also, This series support new MAX77836 extcon device driver on existing MAX14577 device because existed a little difference between MAX77836 and MAX14577. Finally, Fix minor issue of extcon driver. Detailed description for patchset: 1. Add resource-managed functions - Add resource-managed functions to automatically free the memory of extcon structure and to control unregistration behavior as following. This new devm_* functions applied all of extcon drivers in drivers/extcon/. : devm_extcon_dev_register/unregister() : devm_extcon_dev_allocate/free() : extcon_dev_allocate/free() for devm_extcon_dev_allocate/free() 2. Add new MAX77836 extcon device - Support MAX77836 device on existing MAX14577 device driver using different compatible string. This patchset has dependency on MFD/ Regulator/Extcon. So, Lee Jones(MFD Maintainer) created Immutable branch between MFD and Extcon due for v3.16 merge-window and then I merged this patchset from MFD git repo[1] to Extcon git repo. : [1] git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd (branch: ib-mfd-extcon-3.16) 3.

| | * mfd: max14577: Add detection of device typeKrzysztof Kozlowski2014-04-232-23/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues the preparation for adding support for MAX77836 device to existing max14577 driver. Add enum for types of devices supported by this driver. The device type will be detected by matching of_device_id, or i2c_device_id as a fallback. The patch also moves to separate function the code related to displaying DeviceID register values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Add muic prefix to regmap config to differentiate between another regmap config for MAX77836 PMIC node. Additionally remove unused symbols: MAX14577_REG_INVALID and max14577_irq_source. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | commit ca488 (extcon: of: Remove unnecessary function call by using the name of device_node) started using node name instead of device name to get the extcon device. This breaks dwc3-omap since it's not able to get the extcon device anymore. Fixed it by setting edev name of palmas to be the same as its node name.
