This patch-set makes use of the new Capture API by supplying PWM Capture functionality into the already existing STi PWM driver.
v3 => v4: - Keep DTB backward compatibilty
v2 => v3: - Supply DT documentation changes - Submit DTS additions as part of this set - Default Capture and PWM-out number of channels to 0 - Do additional checking, to ensure at least one channel is requested - Use global locking, instead of lock in device data
v1 => v2: - API change - Use a struct to carry the result back to the caller - Use 'struct pwm' to store device specific data - Make timeout configurable - Don't use clear_bit(), instead use raw bit logic - Propagate return value of platform_get_irq() - Don't cast to (void *) - Move to subsystem terminology (channels => devices) - Remove channel select feature - Enable Capture IP during capture
