Annotated Snippet

What:		/sys/bus/platform/drivers/aspeed-uart-routing/\*/uart\*
Date:		September 2021
Contact:	Oskar Senft <osk@google.com>
		Chia-Wei Wang <chiawei_wang@aspeedtech.com>
Description:	Selects the RX source of the UARTx device.

		When read, each file shows the list of available options with currently
		selected option marked by brackets "[]". The list of available options
		depends on the selected file.

		e.g.
		cat /sys/bus/platform/drivers/aspeed-uart-routing/\*.uart_routing/uart1
		[io1] io2 io3 io4 uart2 uart3 uart4 io6

		In this case, UART1 gets its input from IO1 (physical serial port 1).

Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
