When the WiFi support was added to the IGEP0030 board, the MMC subsystem did not provide a mechanism to define power sequence providers. So a DT hack was used to toggle the WiFi chip reset and power down pins by using fake fixed regulators whose enable GPIO was the GPIOs connected to these pins. But now the simple MMC power sequence provider can be used for this and the workaround removed.
