Two drivers (atmel-pwm-bl and leds-atmel-pwm) currently depend on the atmel_pwm driver to have bound to any pwm-device before their devices are probed.
The first patch adds deferred-probing support to the atmel_pwm driver to handle such dependencies. Note that the atmel-pwm-bl driver in linux-next supports deferred probing since commit 9d3fde86b ("backlight: atmel-pwm-bl: fix deferred probe from __init").
Although deferred probing is sufficient to deal with the dependency problem, relying on deferred probing for the backlight driver is not desirable as it may cause unnecessary delays before enabling the backlight at boot. The second patch fixes this by making sure pwm-devices are probed before any backlight devices.
