I am not sure where to post this, but a bunch of omap boards uses either the WL12 or WL18xx Wireless chips, and I have a generic question regarding the 'regulators' we use to set the enable pin on the WiFi chips. When digging around in the mmc drivers, I found a driver called "mmc-pwrseq-simple" It appears to do exactly what we want (ie, turn on the WiFi chip) without having to create a separate fixed regulator, but it also has the added functionality of enabling an external clock signal. This mmc-pwrseq-simple driver appears to be referenced from the MMC level with the reference like "mmc-pwrseq = <&usdhc1_pwrseq>;" or something similar. Should we use this type of mechanism instead of the simple regulators to enable/disable the WL12 and/or WL18xx chips? I am not sure of the OMAP MMC/SD controller utilizes the "mmc-pwrseq" entry in the node or not. adam
