Thanks. > > With this patch applied only the pwm-ab8500 driver is left not using -1 > for base. pwm-ab8500 is assigning ab8500->chip.base as pdev->id. At least in the DT case pdev->id is always -1(as of today). So, base is being allocated dynamically in case of DT. Thanks and regards, Lokesh > > Best regards > Uwe >
