Not needed. That way we have to rename all our omap2_* varients to omap2plus. omap4_* is assumed to be omap4 and onwards just like omap2_* >> +{ >> + int ret; >> + >> + if (omap_rev() == OMAP4430_REV_ES1_0) { > we have ID detection for OMAP5430_REV_ES1_0 in arch/arm/mach-omap2/id.c > However, we do not support PM, so might as well use it to skip init? Well the plan is to remove OMAP5 ES1.0 completely so no need to add more checks. As already mentioned ES1.0 is not going to be supported in mainline kernel.

OMAP5 has backward compatible PRCM block and it's programming model is mostly similar to OMAP4. Same is going to be maintained for future OMAP4 based SOCs. Hence consolidate the OMAP4 power management code so that it can be re-used on OMAP5 and later devices. With consolidated code, let basic power management code build and initialise on OMAP5 devices.
