drivers: w1 introduce 1-wire api and common code This commit introduces a new api for the Dallas 1-wire protocol. The api includes link functions for read and write operations on bit, byte, and block level, as well as functions to reset and lock the bus. The bus configuration is derived from the device tree and can be queried using w1_slave_count routine. Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>

drivers: kconfig: unify menuconfig title strings Unify the drivers/*/Kconfig menuconfig title strings to the format "<class> [(acronym)] [bus] drivers". Including both the full name of the driver class and an acronym makes menuconfig more user friendly as some of the acronyms are less well-known than others. It also improves Kconfig search, both via menuconfig and via the generated Kconfig documentation. Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>

crc: Make the build of crc function dependent on a Kconfig Add CONFIG_CRC for building CRC related routines. CRC routines are now being built for each application, whether used or not and are add in the build system unconditionally. Keep CONFIG_CRC enabled by default for now and until all users have converted to use the new option. Partial fix for #50654 Signed-off-by: Anas Nashif <anas.nashif@intel.com>

drivers/w1: add 1-wire shell This commit implements shell support for 1-Wire. Commands for bus-reset, bit-, byte-, and block- communication, as well as search and configuration are implemented. - write_byte, and write_block perform a reset before, in case the option "-r" is passed. - using read_io_options() function to parse the reset option, as this allows to easily add further options in the future. - configuration type can be specified either as number or as name.

drivers: ds2482-800: Add driver This adds a driver for the DS2482-800 1-wire multi channel bus driver. The driver uses a split architecture in order to share a common lock among all configured channels of a single IC. Signed-off-by: Caspar Friedrich <c.s.w.friedrich@gmail.com>

drivers/w1: driver for ds2485 1-Wire master This commit introduces the 1-wire master driver for maxim ds2485. The ds2485 master has nearly the same (1-wire) feature set and i2c-interface as the ds2477. Therefore the common parts are extracted, but to avoid any nda troubles only the ds2485 specific part is included. Compared to older 1-wire masters, the ds2485 supports higher level commands, supporting multi byte operations, search next, automatic crc calculation. In this driver only basic read and write operations are supported, further hardware features are not yet utilized by the driver. Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>

drivers: w1: add zephyr-serial driver The zephyr-serial w1 driver introduced in this commit implements all routines for the w1 api on top of the zephyr serial driver. W1 bit read, write, and reset operations are executed by issuing polling zephyr serial byte read and write operations. The driver should be usable on most platforms in zephyr that have implemented support for the polling procedures of the serial driver. As not all serial drivers are implemented exactly the same minor additional quirks may be needed on some platforms. The most notable difference of polling serial driver implementations seems to be that some return immediately from poll_out after the transmission was started(e.g. STM32) and others wait until the transmission was completed before returning from poll_out (e.g. NRF). While this has influence on the timeout, both types are supported by this driver because the driver waits for a configurable time period until it terminates the read. The driver needs an appropriate open drain interface to be able to communicate with slaves. In the simpliest case this might be achived by configuring the mcu pins in open-drain configuration with a (sufficiently small) pull-up to 3V3/5V. Otherwise an external circuit needs to provide this interface. Overdrive and Standard Speed modes are supported by this driver. Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>

drivers: w1 introduce 1-wire net layer api This commit introduces a new api for the net layer of Dallas 1-wire protocol. For single drop configurations w1_read_rom, and w1_skip_rom commands are provided. For multidrop configurations w1_match_rom, w1_resume_command, w1_search_rom, and w1_search_alarm routines are provided as well. Additionally, the reset_select routine, conditionally depending on the bus configuration, either executes a match_rom, or a skip rom command. A w1_write_read command simplifies the typical scenario of addressing a device, writing a few bytes to the device and reading back the answer. Additionally w1_crc8, and w1_crc16 are added as wrappers around the zephyr in-tree crc8 and crc16_reflect implementations. The former may be used to verify the validity of the rom id, while the latter is used for integrity checking of many eeprom, and authenticator commands. The general search command does not support filtering on the family code. Signed-off-by: Thomas Stranger <thomas.stranger@outlook.com>

drivers: w1: Make 1-Wire Skip ROM cmd. optional For systems with a true dynamic 1-Wire nature, the 1-Wire devices cannot be defined in the DeviceTree (the number of slaves in the system is not known during the build time). In other words, there are no pre-defined 1-Wire devices on the bus in DeviceTree, and thus the slave_count variable is always zero. That means the skip_rom functionality will always be called even if there are multiple devices connected to the bus. This commit allows the user to override this original behavior and avoid the skip_rom call by ignoring the slave count variable. Also, this work preserves full backward compatibility.

This option will ignore the number of 1-Wire
slave devices defined in the DTS. Specifically,
this option avoids the SKIP ROM command,
which is otherwise used in case of a single
1-Wire slave on the bus. In most cases, enabling
this option is not needed, yet it is essential
if multiple 1-Wire devices unspecified in the
DTS are interfaced.
