tty: serial: Add Nuvoton ma35d1 serial driver support

2023-06-19T13:42:26+00:00

This adds UART and console driver for Nuvoton ma35d1 Soc. It supports full-duplex communication, FIFO control, and hardware flow control. Command line set "console=ttyNVT0,115200", NVT means Nuvoton MA35 UART port. The UART driver probe will create path named "/dev/ttyNVTx".

serial: cpm_uart: Fix a COMPILE_TEST dependency

2023-05-30T11:25:47+00:00

In a COMPILE_TEST configuration, the cpm_uart driver uses symbols from the cpm_uart_cpm2.c file. This file is compiled only when CONFIG_CPM2 is set. Without this dependency, the linker fails with some missing symbols for COMPILE_TEST configuration that needs SERIAL_CPM without enabling CPM2. This lead to: depends on CPM2 || CPM1 || (PPC32 && CPM2 && COMPILE_TEST) This dependency does not make sense anymore and can be simplified removing all the COMPILE_TEST part.

serial: make SiFive serial drivers depend on ARCH_ symbols

2023-04-20T11:40:38+00:00

As part of converting RISC-V SOC_FOO symbols to ARCH_FOO to match the use of such symbols on other architectures, convert the SiFive serial driver Kconfig entries from the SOC_ symbols to ARCH_ instead.

tty: serial: remove obsolete config SERIAL_SAMSUNG_UARTS_4

2023-03-29T08:53:14+00:00

Commit 1ea35b355722 ("ARM: s3c: remove s3c24xx specific hacks"), allows simplifying the whole config logic for SERIAL_SAMSUNG_UARTS, and did this config simplification. However, it misses that SERIAL_SAMSUNG_UARTS_4's effect was just to control SERIAL_SAMSUNG_UARTS, and with the commit's change, the config SERIAL_SAMSUNG_UARTS_4 has no remaining effect and can be deleted. Remove this obsolete config SERIAL_SAMSUNG_UARTS_4.
