About the name field in the hwmod entry: the SR code checks on the value of "smartreflex_mpu_iva" to differentiate the SR IP blocks and to apply the correct parameters to each of them. Cf. the function sr_set_regfields in drivers/power/avs/smartreflex.c. The patch should change the name of the hwmod entry as well, can you fold this change in the current patch? Note: I know the name "smartreflex_mpu_iva" is not perfect since it does not apply to all OMAP3 variants, maybe we could change the SR code to be more generic. Nishant, what do you think?
