[PATCH v1 0/2] add support for GPIO based counter

[Oleksij Rempel]

Add support for GPIO based pulse counter. For now it can only count
pulses. With counter char device support, we will be able to attach
timestamps and measure actual pulse frequency.

Never the less, it is better to mainline this driver now (before chardev
patches go mainline), to provide developers additional use case for the counter
framework with chardev support.
