ARM: OMAP2xxx: hwmod data: start to fix the IVA1, IVA2 and DSP
N800 logs this message on boot: [ 0.182281] omap_hwmod: iva: cannot be enabled for reset (3) Fix by creating basic IVA1 and DSP hwmods for OMAP2420, and a basic IVA2 hwmod for OMAP2430. There is still more information to be added, but this should resolve the immediate issue. Signed-off-by: Paul Walmsley <paul@pwsan.com>
