OK, will take care in my next patch.

the desc is not available here in mfd file and so not possible. Each regulator register as different platform driver and hence does not have the other instance platform data. However, this will be get fixed once my next patch for moving the dt parsing from mfd core to regulator is there. At that time I will take care of this.

The function tps6586x_regulator_set_slew_rate() use the platform data which is not available if init_data is not provided by platform.
