The rk3288 has the ability to invert + struct rockchip_pwm_chip *pc = to_rockchip_pwm_chip(chip); + + if (!pc->data->has_invert) + return -ENOSYS; +At the kernel summit hpa also mentioned that ENOSYS should only be used for missing syscalls. Not sure what error code would suit better here though...
Luckily this code is gone now. See v4 of the series. ;) -Doug
