2016-12-09dt: pwm: bcm2835: fix typo in clocks property nameVladimir Zapolskiy1-1/+1
According to the examples of BCM2835 PWM device nodes there is a typo in 'clocks' property name, which is a common property name on clock consumer side to store a phandle to an input clock. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Rob Herring <robh@kernel.org>
2016-11-29pwm: Add PWM driver for HiSilicon BVT SOCsyuanjian1-0/+21
Add PWM driver for the PWM controller found on HiSilicon BVT SoCs such as Hi3519V100, Hi3516CV300, etc. The PWM controller is primarily in charge of controlling the P-Iris lens.

2016-09-08dt-bindings: pwm: sti: Update DT bindings for capture supportLee Jones1-3/+5
In order to support capture of PWM signals a new clock as well as an interrupt line are required. Furthermore a new property is introduced that allows the number of capture channels to be specified. Typically there will be less capture channels than output channels, since all channels have the latter capability, but only some have support for capture.
