dm: treewide: Use uclass_first_device_err when accessing one device

2022-10-18T03:17:12Z

There is a number of users that use uclass_first_device to access the first and (assumed) only device in uclass. Some check the return value of uclass_first_device and also that a device was returned which is exactly what uclass_first_device_err does. Some are not checking that a device was returned and can potentially crash if no device exists in the uclass. Finally there is one that returns NULL on error either way. Convert all of these to use uclass_first_device_err instead, the return value will be removed from uclass_first_device in a later patch. Signed-off-by: Michal Suchanek Reviewed-by: Simon Glass

serial: Call flush() before changing baudrate

2022-09-24T15:34:38Z

Changing baudrate is a sensitive operation. To ensure that U-Boot messages printed before changing baudrate are not lost, call new U-Boot console flush() function. Signed-off-by: Pali Rohár Reviewed-by: Simon Glass

serial: Implement serial_flush() function for console flush() fallback

2022-09-24T15:34:37Z

Like in all other console functions, implement also serial_flush() function as a fallback int console flush() function. Flush support is available only when config option CONSOLE_FLUSH_SUPPORT is enabled. So when it is disabled then provides just empty static inline function serial_flush().

serial: Implement flush callback

2022-09-24T14:47:01Z

UART drivers have putc/puts functions which just put characters into HW transmit queue and do not wait until all data are transmitted. Implement flush callback via serial driver's pending(false) callback which waits until HW transmit all characters from the queue. Signed-off-by: Pali Rohár Reviewed-by: Simon Glass

serial: mtk: add support for using dynamic baud clock souce

2022-09-23T19:09:15Z

The baud clock on some platform may change due to assigned-clock-parent set in DT. In current flow the baud clock is only retrieved during probe stage. If the parent of the source clock changes after probe stage, the setbrg will set wrong baudrate. To get the right clock rate, this patch records the baud clk struct to the driver's priv, and changes the driver's flow to get the clock rate before calling _mtk_serial_setbrg().
