Afzal	b1ec844b2f	PAS: add constant torque control type ... For gearless electric bicycles, riding up the slope and during start, good torque support from the motor helps the rider ride with less effort. Pedal assist based on cadence provides higher torque with higher pedalling speed. In the situations mentioned above, where user naturally pedals slow, aid from cadence based system is less. On a geared setup, changing to low gear comes to the rider's help. Here another control type is provided - Constant Torque, whenever the rider pedals, motor would provide constant torque. The torque value can be set using 'PAS max current' setting thus acting as fine PAS assist level. This type of control is similar to 'Basic PAS, constant throttle' of 'PAS Control Schemes' [1], with the difference that throttle setting in that article corresponds to speed, while here torque. Also riding experience on some of the popular (not high end) e-bicycles having PAS indicates they might be having this kind of control internally.

Marcos Chaparro	33b5d5c1ba	Pedal assist support (PAS) ... This commit enables cadence-based pedal assist for ebikes using quadrature-style pedal speed sensors. There are 2 operation modes: * PAS only: Motor current is based only on pedal feedback * ADC + PAS: The code will use both ADC and pedal feedback and use the strongest command to provide seamless overlap when the user is pedalling and requests extra torque with the throttle.
