serial: cpm_uart: Remove cpm_uart/ subdirectory

2023-08-04T13:08:30+00:00

cpm_uart/ subdirectory only has cpm_uart_core.c and cpm_uart.h now. Move them up and remove cpm_uart/ directory while renaming cpm_uart_core.c as cpm_uart.c Signed-off-by: Christophe Leroy Link: https://lore.kernel.org/r/9b8b8f89fc386480030f5339abe307541ae436a6.1691068700.git.christophe.leroy@csgroup.eu Signed-off-by: Greg Kroah-Hartman

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: core: Start managing serial controllers to enable runtime PM

2023-05-31T09:46:59+00:00

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

2023-05-13T10:47:26+00:00

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

2022-02-26T09:03:21+00:00

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

serial: ifx6x60: Remove driver for deprecated platform

2021-01-26T18:21:49+00:00

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.
