ARM: OMAP3: fix iva mmu programming issues (200a274f) · Commits · 戴 / test

The IVA MMU is not functional when used through the hwmod and omap_device layers. Add fixes to clockdomain and hwmod data to have it functional. The hwmod changes are needed to enable the clock, and the SWSUP change is needed to wakeup the domain because the power domain is programmed to be in RET, and there is no automatic power domain switching to ON.
