w1: add UART w1 bus driver

2024-02-15T14:02:33Z

Add a UART 1-Wire bus driver. The driver utilizes the UART interface via the Serial Device Bus to create the 1-Wire timing patterns. The driver was tested on a "Raspberry Pi 3B" with a DS18B20 and on a "Variscite DART-6UL" with a DS18S20 temperature sensor. The 1-Wire timing pattern and the corresponding UART baud-rate with the interpretation of the transferred bytes are described in the document: Link: https://www.analog.com/en/technical-articles/using-a-uart-to-implement-a-1wire-bus-master.html In short, the UART peripheral must support full-duplex and operate in open-drain mode. The timing patterns are generated by a specific combination of baud-rate and transmitted byte, which corresponds to a 1-Wire read bit, write bit or reset.

w1: Add AXI 1-wire host driver for AMD programmable logic IP core

2023-11-15T21:04:06Z

Add a host driver to support the AMD 1-Wire programmable logic IP block. This block guarantees protocol timing for driving off-board devices such as thermal sensors, proms, etc. Add file to MAINTAINERS Co-developed-by: Thomas Delev Signed-off-by: Thomas Delev Signed-off-by: Kris Chaplin Link: https://lore.kernel.org/r/20231107180814.615933-3-kris.chaplin@amd.com Signed-off-by: Krzysztof Kozlowski

w1: remove ds1wm driver

2023-02-01T16:23:38Z

This driver was used by the mfd/asic3 and mfd/htc-pasic3 drivers, but both of those are removed as part of the PXA spring cleaning, which leaves the w1 support orphaned as well. Cc: Evgeniy Polyakov Cc: Szabolcs Gyurko Acked-by: Robert Jarzmik Signed-off-by: Arnd Bergmann

w1: add 1-wire master driver for IP block found in SGI ASICs

2019-09-04T12:34:31Z

Starting with SGI Origin machines nearly every new SGI ASIC contains an 1-Wire master. They are used for attaching One-Wire prom devices, which contain information about part numbers, revision numbers, serial number etc. and MAC addresses for ethernet interfaces. This patch adds a master driver to support this IP block. It also adds an extra field dev_id to struct w1_bus_master, which could be in used in slave drivers for creating unique device names.

w1: Allow compile test of GPIO consumers if !GPIOLIB

2018-06-26T07:46:27Z

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. Signed-off-by: Geert Uytterhoeven Acked-by: Linus Walleij Acked-by: Evgeniy Polyakov Signed-off-by: Linus Walleij
