Each SoC has two TCB blocks, each one including three independent channels.The following series adds support for two counter modes: increase and quadrature decoder. As for the atmel clocksource and pwm, the counter driver needs to fill some tcb capabilities in order to operate with the right configuration. This is achieved in first patch of this series. Please feel free to comment.
