> In order for suspend and resume to work with genpd on am3, we must keep
> l3 main clock always on. Otherwise prm_omap driver will shut down the l3
> main clock on suspend when simple-pm-bus and GENPD_FLAG_PM_CLK are used.
> Note that we already keep the l3 main clock always on with the legacy
> platform code.
>
> Later on we may want to start managing the l3 main clock with a dedicated
> interconnect driver instead of using simple-pm-bus and GENPD_FLAG_PM_CLK.
