Commit 625326ea9c84 ("MIPS: Remove PNX833x alias NXP_STB22x") removed support for PNX833x, so it's time to remove serial driver, too. Signed-off-by: Thomas Bogendoerfer Link: https://lore.kernel.org/r/20201106130332.103476-1-tsbogend@alpha.franken.de Signed-off-by: Greg Kroah-Hartman

serial: Remove duplicated macro definition of port type

2020-07-06T12:06:08+00:00

There exists the same macro definition of port type from 0 to 13 in include/uapi/linux/serial.h, remove these duplicated code in include/uapi/linux/serial_core.h which includes the former header.

tty: serial: Fix PORT_LINFLEXUART definition

2019-10-04T13:57:51+00:00

The port type macros should have different values for different devices. Currently, PORT_LINFLEXUART conflicts with PORT_SUNIX.

tty: serial: Add linflexuart driver for S32V234

2019-09-04T10:43:54+00:00

Introduce support for LINFlex driver, based on: - the version of Freescale LPUART driver after commit b3e3bf2ef2c7 ("Merge 4.0-rc7 into tty-next"); - commit abf1e0a98083 ("tty: serial: fsl_lpuart: lock port on console write"). In this basic version, the driver can be tested using initramfs and relies on the clocks and pin muxing set up by U-Boot. Remarks concerning the earlycon support: - LinFlexD does not allow character transmissions in the INIT mode (see section 47.4.2.1 in the reference manual[1]). Therefore, a mutual exclusion between the first linflex_setup_watermark/linflex_set_termios executions and linflex_earlycon_putchar was employed and the characters normally sent to earlycon during initialization are kept in a buffer and sent afterwards. - Empirically, character transmission is also forbidden within the last 1-2 ms before entering the INIT mode, so we use an explicit timeout (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to linflex_setup_watermark. - U-Boot currently uses the UART FIFO mode, while this driver makes the transition to the buffer mode. Therefore, the earlycon putchar function matches the U-Boot behavior before initializations and the Linux behavior after.
