serial: sc16is7xx: rename Kconfig CONFIG_SERIAL_SC16IS7XX_CORE

2024-06-04T12:10:28+00:00

Commit d49216438139 ("serial: sc16is7xx: split into core and I2C/SPI parts (core)") renamed SERIAL_SC16IS7XX_CORE by SERIAL_SC16IS7XX. This means that some configs should have been updated when I submitted the original patch, but unfortunately they were not. Geert mentioned for example: arch/mips/configs/cu1??0-neo_defconfig Rename SERIAL_SC16IS7XX to SERIAL_SC16IS7XX_CORE so that existing configs will still work correctly.

serial: sc16is7xx: split into core and I2C/SPI parts (core)

2024-04-11T12:08:08+00:00

Split the common code from sc16is7xx driver and move the I2C and SPI bus parts into interface-specific source files. sc16is7xx becomes the core functions which can support multiple bus interfaces like I2C and SPI. No functional changes intended. Also simplify and improve Kconfig entries. - Capitalize SPI keyword for consistency - Display list of supported ICs each on a separate line (and aligned) to facilitate locating a specific IC model - Add Manufacturer name at start of description string - Add UART keyword to description string Suggested-by: Andy Shevchenko Signed-off-by: Hugo Villeneuve Link: https://lore.kernel.org/r/20240409154253.3043822-4-hugo@hugovil.com 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.
