To update further, it seems to be working on zoom3 with ttyS0 with following combination of patches: 1. [RFC,part2,v1,4/4] omap3: zoom 2/3: Change debugboard serial port id [RFC,part2,v1,3/4] omap3: 3630sdp: Explicitly enable all UARTs [RFC,part2,v1,2/4] omap3: zoom2/3 / 3630sdp: Don't init always all uarts [RFC,part2,v1,1/4] omap2/3/4: serial: rename omap_serial_init 2. [RESEND,PATCH/RFC] OMAP2: serial.c: Fix number of uarts in early_init 3. [RFC,v3,6/6] omap3: serial: Fix uart4 handling for 3630 [RFC,v3,5/6] OMAP3: PRCM: Consider UART4 for 3630 chip in prcm_setup_regs [RFC,v3,4/6] OMAP clock: Add uart4_ick/fck definitions for 3630 [RFC,v3,3/6] ARM: OMAP3630: PRCM: Add UART4 control bits [RFC,v3,2/6] omap2/3/4: serial: Remove condition for getting uart4_phys [RFC,v3,1/6] OMAP3: serial: Check for zero-based physical addr -Manjunath-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
