The latest mikrobus Click ID EEPROM has custome family code DS28E36
EEPROMs, this commit adds support for that and also fixes the following
issues:
* Failing to get gpio array (due -EPROBEDEFER was logged as error, but is
not fatal)
* W1 master continously performs W1 search which causes stray W1 devices
to be detected due to noise, fix that by decreasing the search count.

Eg:

alias:          serdev:ttydev_serdev
alias:          serdev:ttydev

root@qt5022:~#

Currently,a serdev device driver can only be used with devices that are
nodes of a device tree, or are part of the ACPI table.id_table will be
used for devices that are not part of the device tree nor the ACPI table
(example: device on greybus gbphy created uart).

corresponding modalias field is introduced to name the driver to be
used with the device, required device(s) that are neither described
by device tree nor ACPI table.

serdev_device_uevent is also extended for modalias devices.

This Patch series is an update to the mikroBUS driver
with support for serdev devices and fixed regulator.

RFC v1 Patch : https://lkml.org/lkml/2020/7/24/518

 .
The mikrobus driver is updated to add mikrobus ports from device-tree
overlays, the debug interfaces for adding mikrobus ports through sysFS
is removed, and the driver considers the extended usage of mikrobus
port pins from their standard purposes.

change log:
        v2: support for adding mikroBUS ports from DT overlays,
        remove debug sysFS interface for adding mikrobus ports,
        consider extended pin usage/deviations from mikrobus standard
        specifications,
        use greybus CPort protocol enum instead of new protcol enums
        Fix cases of wrong indendation, ignoring return values, freeing
        allocated resources in case of errors and other style suggestions

This reverts commit bd1e336a.

This reverts commit 2338e7bc.

Add the Greybus host driver for BeaglePlay board by BeagleBoard.org.

The current greybus setup involves running SVC in a user-space
application (GBridge) and using netlink to communicate with kernel
space. GBridge itself uses wpanusb kernel driver, so the greybus messages
travel from kernel space (gb_netlink) to user-space (GBridge) and then
back to kernel space (wpanusb) before reaching CC1352.

This driver directly communicates with CC1352 (running SVC Zephyr
application). Thus, it simplifies the complete greybus setup eliminating
user-space GBridge.

This driver is responsible for the following:
- Start SVC (CC1352) on driver load.
- Send/Receive Greybus messages to/from CC1352 using HDLC over UART.
- Print Logs from CC1352.
- Stop SVC (CC1352) on driver load.
