This series extends support to newer Armada variants that use CP11x and AP80x, like Armada 8K and 7K. This series adds adds the 'pwm-offset' property to DT binding. 'pwm-offset' points to the base of A/B counter registers that determine the PWM period and duty cycle. The existing PWM DT binding reflects an arbitrary decision to allocate the A counter to the first GPIO block, and B counter to the other one. In attempt to provide better future flexibility, the new 'pwm-offset' property always points to the base address of both A/B counters. The driver code still allocates the counters in the same way, but this might change in the future with no change to the DT. Tested AP806 and CP110 (both) on Armada 8040 based system.
