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 in v1 review.

We are going to need the overlays to appear on sysfs with runtime global properties (like master enable) so turn them into kobjects. They have to be in sysfs so that people can have information about the overlays applied in the system, i.e. where their targets are and whether removal is possible. In a future more attributes can be added in a backwards compatible manner. Signed-off-by:

Changes since v4: - Loading fix for multiple overlays as found out by Geert Uytterhoeven <geert@linux-m68k.org> Changes since v3: - Fixed compilation on SPARC & Xtensa Changes since v2: - Removed ifdef CONFIG_OF_OVERLAY (since for now it's required) - Created a documentation entry - Slight rewording in Kconfig Changes since v1: - of_resolve() -> of_resolve_phandles().
