One additional function was needed serial8250_get_baud_rate() for the driver to work correctly for baud rate calculation. While at it also try to clarify a long standing issue with new UART driver when adding new ids for uart_config[]. [1] https://lore.kernel.org/all/20250209210241.2622309-1-benjamin.larsson@genexis.eu/ Changes v5: - Improve 8250 YAML schema with enum - Keep alphabetical order for YAML schema Changes v4: - Add Review tag - Add errno and types header - Drop redundant () from comment - Use define for get_divisor Changes v3: - Address review from ai bot - Add all missing kernel headers - Improve divisor calculation - Fix wrong uart config table - Simplify divisor table handling Changes v2: - Drop intermediate patch - Use .set_divisor OPs - Use div_u64 instead of / 40 for 32 bit overflow - Drop dedicated match table and use compatible for type Changes compared to [1]: - Fix all formal error - Use better compatible names - Drop unneeded header - Drop usage of irq (it's filled by the generic function) - General code cleanup and reorg - Split to patch and add the UAPI map patch Benjamin Larsson (1): dt-bindings: serial: 8250: Add Airoha compatibles Christian Marangi (2): dt-bindings: serial: 8250: Reorganize compatible to single enum serial: 8250: Add Airoha SoC UART and HSUART support .../devicetree/bindings/serial/8250.yaml | 32 +-- drivers/tty/serial/8250/8250.h | 6 + drivers/tty/serial/8250/8250_airoha.c | 187 ++++++++++++++++++ drivers/tty/serial/8250/8250_port.c | 16 ++ drivers/tty/serial/8250/Kconfig | 11 ++ drivers/tty/serial/8250/Makefile | 1 + 6 files changed, 240 insertions(+), 13 deletions(-) create mode 100644 drivers/tty/serial/8250/8250_airoha.c -- 2.53.0
