* leds: pca963x: workaround group blink scaling issueMatt Ranostay2016-11-221-0/+3
| | | | | | | | | | PCA9632TK part seems to incorrectly blink at ~1.3x of the programmed rate. This patchset add a nxp,period-scale devicetree property to adjust for this misconfiguration.

* leds: Introduce userspace LED class driverDavid Lechner2016-11-221-0/+36
| | | | | | | | | | | | | | This driver creates a userspace leds driver similar to uinput. New LEDs are created by opening /dev/uleds and writing a uleds_user_dev struct. A new LED class device is registered with the name given in the struct. Reading will return a single byte that is the current brightness. The poll() syscall is also supported. It will be triggered whenever the brightness changes. Closing the file handle to /dev/uleds will remove the leds class device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suggested patch solves two issues: 1) Currently documentation is unclear whether `make kselftest` should be run before or after kernel was installed and booted. `make help` gives a clear answer on that: "kselftest - Build and run kernel selftest (run as root). Build, install, and boot kernel before running kselftest on it." 2) Documentation states that `make kselftest` executes "unit" tests. Technically it's not a _unit_ test if it requires to install an application first. It's either integration or system test. To not to confuse a user I suggest not to use a word "unit".

But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them.

Although this makes complete sense, some I2C adapters may have subnodes which are not I2C slaves but subnodes presenting other features. For example some Tegra devices have an I2C interface which may share its pins with other devices. In order to share these pins using the pinctrl framework, it is necessary to add subnodes to the I2C device node that represent these pins. To allow I2C adapters to have non-I2C specific subnodes in device-tree that are not parsed by the I2C driver core, add support for an optional 'i2c-bus' subnode where I2C slaves can be placed. If the 'i2c-bus' subnode is present then all I2C slaves must be placed under this subnode.
