Ok, seems good to me. NOTE: I'm personally not convinced that adding the "set_load" calls into the SDHCI driver actually makes any sense. I believe it adds complexity for no benefit. The only time you ever need to should ever be fiddling with "set_load" calls is if the rail you're controlling has some hope of being able to run at a lower power mode. If there's no hope of it being at a lower power mode then the constraints on the rail should just force it to high power mode and be done with it. The patch here (using regulator-system-load) is one way to force it to a high power mode and seems fine, but there are other ways. See a previous discussion [1]. NOTE: IIRC the "ongoing work" patch you pointed at always sets the load to a fixed level to turn it to "high power mode" when the regulator is turned on and undoes that set_load when the regulator is turned off. That's no longer needed as of commit 5451781dadf8 ("regulator: core: Only count load for enabled consumers"). If someone comes up with a case where it's useful to keep the SD card rail turned on but in "low power mode" _then_ we should actually consider adding set_load to the SD card driver.
