There are dozens of devicetree-related warnings spewed on boot (many pertaining to missing regulators). At the moment, however, I'm most interested in this, cpufreq-cpu0 cpufreq-cpu0.0: no of_node; not parsing pinctrl DT cpu cpu0: dummy supplies not allowed cpufreq_cpu0: failed to get cpu0 regulator: -19 cpufreq_cpu0: failed to get cpu0 clock: -2 cpufreq-cpu0: probe of cpufreq-cpu0.0 failed with error -2 What is the status of cpufreq on the PandaBoard? Is this expected to work? More generally, if one wants a fairly recent kernel supporting the PandaBoard's hardware what kernel tree should be used? Is mainline not yet appropriate? Is linux-next preferred? Perhaps a ti-maintained tree?
