It should be part of 2nd patch? No, not really, include/bindings are also considered part of bindings. This patch alone should be enough for you to add the DT nodes. regards Suman > >> index babd08a1d226..76b07826ed05 100644 >> --- a/include/dt-bindings/bus/ti-sysc.h >> +++ b/include/dt-bindings/bus/ti-sysc.h >> @@ -18,6 +18,10 @@ >> #define SYSC_DRA7_MCAN_ENAWAKEUP (1 << 4) >> +/* PRUSS sysc found on AM33xx/AM43xx/AM57xx */ >> +#define SYSC_PRUSS_SUB_MWAIT (1 << 5) >> +#define SYSC_PRUSS_STANDBY_INIT (1 << 4) >> + >> /* SYSCONFIG STANDBYMODE/MIDLEMODE/SIDLEMODE supported by hardware */ >> #define SYSC_IDLE_FORCE 0 >> #define SYSC_IDLE_NO 1 >> >

Well I don't care either way, sort of would prefer to have this with the device patch in case somebody starts back porting driver changes. Anyways, let's wayt for Rob's ack on this, maybe he has also preference on the ti-sysc.h changes. Regards, Tony
