Name: LRW UART: Patch series for LRW UART driver
URL: https://patchwork.kernel.org/project/linux-riscv/list/?series=1053862
Version: 1

Add documentation for LRW UART devicetree bindings. Signed-off-by: Wenhong Liu <liu.wenhong35@zte.com.cn> Signed-off-by: Qingtao Liu <liu.qingtao2@zte.com.cn> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>

This commit introduces a serial driver for the LRW UART controller Key features implemented: - Support for FIFO mode (16-byte depth) - Baud rate configuration - Standard asynchronous communication formats: * Data bits: 5, 6, 7, 8, 9 bits * Parity: odd, even, fixed, none * Stop bits: 1 or 2 bits - Hardware flow control (RTS/CTS) - Multiple interrupt reporting mechanisms Signed-off-by: Wenhong Liu <liu.wenhong35@zte.com.cn> Signed-off-by: Qingtao Liu <liu.qingtao2@zte.com.cn> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
