Then we may need to avoid this - but as far as I can tell the amba-pl011 driver only disables the clock in error cases (or when shutting down). Maybe we just need to disable the shutdown of the plld? >> Is this maybe related to the uart0_pclk, uart1_pclk, apb_pclk >> clocks created and registered in bcm2835_init_clocks? > > Related or not i think we should get the rid off them. A quick test shows that an empty bcm2835_init_clocks does not change the basic kernel-boot behavior and everything seems to work. So we probably should remove it in: * arch/arm/mach-bcm/board_bcm2835.c (call) * drivers/clk/bcm/clk-bcm2835.c (function definition) Martin -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
