The following message is logged: omap_hwmod: sl2if: cannot be enabled for reset (3) This is probably because the SL2IF is still being held in hardreset. The SL2IF's hardreset line is shared with one of the IVAHD's hardreset lines; see for example Table 3-536 "RM_IVAHD_RSTCTRL" in the OMAP4430 TRM Rev. AA (SWPU231AA). To work around this, add the SL2IF's hardreset line to the hwmod data. This is correct from a hardware perspective and also will prevent the hwmod from attempting to enable the SL2IF during reset. The driver for this IP block will need to handle its integration until the appropriate way to handle the IVAHD integration can be elucidated.
