Another thing, I boot the board from the NAND, therefore I can configure omap_hsmmc as a module.
I noticed that the clock signal is only sent the moment I load the driver. The initialization check every bus you previously configured for anything attached, but so far I haven't solved how to do this once the driver is up and running...
Actually, I haven't had time to look it up. As this is not a concern in my project, it got postponed. This would happen if, for example, unifi_sdio failed to issue the command that starts the bus...
