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.

dm: core: Default to using DEVRES outside of xPL

2026-01-09T15:08:14Z

The devm alloc functions that we have may follow the Linux kernel model where allocations are (almost always) automatically free()'d. However, quite often we don't enable, in full U-Boot, the tracking and free()'ing functionality. This in turn leads to memory leaks because the driver author expects that since the functions have the same name as in the Linux Kernel they have the same behavior. In turn we then get functionally correct commits such as commit 00e1fed93c8c ("firmware: ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually add these calls. Rather than manually tracking allocations and implementing free()s, rework things so that we follow expectations by enabling the DEVRES functionality (outside of xPL phases). This turns DEVRES from a prompted symbol to a symbol that must be select'd, and we now remove our non-managed alloc/free functions from outside of xPL builds.

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
