[PATCH 6/7] omap4: dpll: Add dpll api to control GATE_CTRL [PATCH 7/7] omap4: dpll: Enable auto gate control for all MX postdividers Will fix the following issues.. -1- Autogating support for clkout_x2 nodes (for PER and ABE DPLL) was'nt addressed -2- The clkdcoldo output (dpll_usb_clkdcoldo_ck) of USB dpll did not have the clksel populated and hence gate ctrl for it was'nt getting programmed. ... and post a respin of this series shortly.
