hello! I have PMIC (TWL4030) module connected to the SoC (ARM/OMAP3) via i2c (iicbus). Current solution is that i2c_attach calls bus_generic_attach(dev); which calls my pmic probe/attach functions, but main configuration of PMIC in done after drivers setup by config_intrhook. But I need it to be configured during device attaching, because usb ehci driver depends on it. Is it possbile? I've tried it but it hangs on waiting for i2c interrupt, but someone told me, that interrupts are available during bootup for some time. -- regards aleek
