 menuconfig UART_XLNXPS
 	bool "Xilinx UART Peripheral System (XUARTPS) Chip support"
 	default n
+	---help---
+		This option enables support for the Xilinx UART Peripheral System
+		(XUARTPS) controller, which is commonly found in Xilinx Zynq-7000
+		and Zynq UltraScale+ MPSoC platforms.
+
+		The XUARTPS controller provides full-duplex UART functionality with
+		features such as baud rate generation, FIFO buffers, interrupt
+		support, and hardware flow control (RTS/CTS).
+
+		If you are building a kernel for Xilinx Zynq/Zynq MPSoC platforms
+		and need serial communication via the XUARTPS peripheral, say Y here.
