tty/serial: Sort drivers in makefile

2023-09-18T09:14:43Z

Sort drivers in alphabetic order in Makefile to make it easier to find the correct line. In case the CONFIG and filenames disagree, sort using the filename (but ignoring "serial" prefixes).

tty: serial: Add Nuvoton ma35d1 serial driver support

2023-06-19T13:42:26Z

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: core: Start managing serial controllers to enable runtime PM

2023-05-31T09:46:59Z

We want to enable runtime PM for serial port device drivers in a generic way. To do this, we want to have the serial core layer manage the registered physical serial controller devices. To manage serial controllers, let's set up a struct bus and struct device for the serial core controller as suggested by Greg and Jiri. The serial core controller devices are children of the physical serial port device. The serial core controller device is needed to support multiple different kind of ports connected to single physical serial port device. Let's also set up a struct device for the serial core port. The serial core port instances are children of the serial core controller device. With the serial core port device we can now flush pending TX on the runtime PM resume as suggested by Johan.

serial: 8250: RT288x/Au1xxx code away from core

2023-05-13T10:47:26Z

A non-trivial amount of RT288x/Au1xxx code is encapsulated into ifdeffery in 8250_port / 8250_early and some if UPIO_AU blocks. Create a separate file from them. Also handle errors properly in the cases where RT288x/Au1xxx code is not configured. It seems that 0x1000 mapsize is likely overkill but I've kept it the same as previously (the value was shrunk to that value in commit b2b13cdfd05e ("SERIAL 8250: Fixes for Alchemy UARTs.")). Seemingly, the driver only needs to access register at 0x28 for the divisor latch. The Kconfig side is a bit tricky. As SERIAL_8250_RT288X is bool it can only be =y. It is possible to have SERIAL_8250=m + SERIAL_8250_RT288X=y which required altering when 8250/ is included or the rt288x would not be built.

serial: sunplus-uart: Add Sunplus SoC UART Driver

2022-02-26T09:03:21Z

Add Sunplus SoC UART Driver. SP7021 UART block contains 5 UARTs. There are UART0~4 that supported in SP7021, the features list as below. Support Full-duplex communication. Support data packet length configurable. Support stop bit number configurable. Support force break condition. Support baud rate configurable. Support error detection and report. Support RXD Noise Rejection Vote configurable. UART0 pinout only support TX/RX two pins. UART1 to UART4 pinout support TX/RX/CTS/RTS four pins. Normally UART0 used for kernel console, also can be used for normal uart. Command line set "console=ttySUP0,115200", SUP means Sunplus Uart Port. UART driver probe will create path named "/dev/ttySUPx". https://sunplus.atlassian.net/wiki/spaces/doc/pages/1873412290/13.+Universal+Asynchronous+Receiver+Transmitter+UART Signed-off-by: Hammer Hsieh Link: https://lore.kernel.org/r/1645522563-17183-3-git-send-email-hammerh0314@gmail.com Signed-off-by: Greg Kroah-Hartman
