AM335x RTC feature disabled - kernel changes

Hi TI, We are using AM335x in RTC feature disabled mode. We have not connected external 32.768KHz external crystal. We have only 24MHz crystal oscillator connected to AM335x, all clocks need to derived from AM335x PLLs itself. I understood this crystal is used by timers. I have to change timers parent clock from CLK_32768 to CLK_M_OSC clock. Please correct me if I am wrong here. TIMER1 clock Example: ----------------------- Reg : CLKSEL_TIMER1MS_CLK addr: 0x44e00528 options : 0x0 = SEL1 : Select CLK_M_OSC clock 0x1 = SEL2 : Select CLK_32KHZ clock 0x2 = SEL3 : Select TCLKIN clock 0x3 = SEL4 : Select CLK_RC32K clock 0x4 = SEL5 : Selects the CLK_32768 from 32KHz Crystal Osc Here which option I have to select here ?? Can I get any kernel software patch to work? Our Schematic is as per this document here, http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#RTC Regards & Thanks, Anil.
