Merge patch series "i3c: dw: fix slave device setup and probe issues"

2026-07-22T19:10:22Z

Pranav Tilak says: This series fixes several issues in the DW I3C master driver and related infrastructure that prevented I3C read/write operations, and enables I3C support for Versal Gen 2. Link: https://lore.kernel.org/r/20260709091357.1860417-1-pranav.vinaytilak@amd.com

i3c: dw: fix slave device setup after DAA

2026-07-22T19:10:21Z

i3c_master_add_i3c_dev_locked() incorrectly set master->this to the newly discovered slave device, causing i3c_master_attach_i3c_dev() to skip the attach_i3c_dev() callback. As a result the slave device never got its master_priv (DAT slot index) allocated, free_pos was never updated, and the DAT entry was never written. Fix by removing the incorrect master->this assignment. Store the slave descriptor directly in master->i3cdev[pos] inside dw_i3c_master_attach_i3c_dev() where the DAT slot index is already known. Also check the return value of i3c_master_add_i3c_dev_locked() and skip num_i3cdevs increment on failure, fixing dummy devices shown when no slaves are present on the bus.

i3c: dw: make resets optional in probe

2026-07-22T19:09:54Z

Treat -ENOENT and -ENOTSUPP from reset_get_bulk() as non-fatal to support platforms where no resets are defined in the DTS. The resets property is not yet documented in the DT binding.

treewide: Kconfig: use bool instead of tristate

2026-07-10T21:45:57Z

U-Boot does not support modules, so having tristate options is useless. Therefore this patch does a blind replace of all tristate options to bool tree-wide.

sandbox: Add more dummy functions to mimic other architectures

2025-08-11T21:11:19Z

This adds more common functions found on other architectures that will allow for more compile-testing of drivers. These are either dummy functions as we do not need them or mappings to existing functions, similar to how other architectures handle it. Signed-off-by: Tom Rini
