[PATCHv2] clk: ti: omap5+: dpll: implement errata i810

[Tony Lindgren]

* Tero Kristo <t-kristo at ti.com> [151216 01:00]:
> Errata i810 states that DPLL controller can get stuck while transitioning
> to a power saving state, while its M/N ratio is being re-programmed.
> 
> As a workaround, before re-programming the M/N ratio, SW has to ensure
> the DPLL cannot start an idle state transition. SW can disable DPLL
> idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request
> active by setting a dependent clock domain in SW_WKUP.
> 
> This errata is known to impact OMAP5 and DRA7 chips, but lets enable it
> unconditionally to avoid any potential problems with earlier generation
> SoCs also.
> 
> Signed-off-by: Tero Kristo <t-kristo at ti.com>
> ---
> v2: made the fix to be applied unconditionally on all OMAP3+ SoCs

Thanks looks good to me now:
