Or is this this really not LOCO specific but i.MX53 specific? If this is LOCO specific you should pass NULL as the device pointer. If this is i.MX53 specific we should discuss about adding a imx53_init_sata as then all of this function is not LOCO specific. Have these patches undergone some Linaro internal review? These are really not ready for the wider world. Sascha

On MX53 SOC, the AHCI bus clk can be sourced from internal USB_PHY1 clk, or one external crystal oscillator. I would create external two functions later, one used for internal clk initialization, and the other would be used when external crystal oscillator is used. and move these codes into the internal clk initialization function.
