drivers: bus: add the stm32 debug bus driver

2026-03-25T16:40:22+00:00

Add the stm32 debug bus driver that is responsible of checking the
debug subsystem accessibility before probing the related peripheral
drivers.

This driver is OP-TEE dependent and relies on the STM32 debug access
PTA.

bus: Remove not-going-to-be-supported code for Baikal SoC

2026-03-11T22:43:43+00:00

As noticed in the discussion [1] the Baikal SoC and platforms
are not going to be finalized, hence remove stale code.

There seems to be nothing preventing the driver from being compile
tested so enable that for wider build coverage.

bus: add driver for IMX AIPSTZ bridge

2025-07-01T14:23:21+00:00

The secure AHB to IP Slave (AIPSTZ) bus bridge provides access control
configurations meant to restrict access to certain peripherals.
Some of the configurations include:

	1) Marking masters as trusted for R/W. Based on this
	(and the configuration of the accessed peripheral), the bridge
	may choose to abort the R/W transactions issued by certain
	masters.

	2) Allowing/disallowing write accesses to peripherals.

Add driver for this IP. Since there's currently no framework for
access controllers (and since there's currently no need for having
flexibility w.r.t the configurations) all this driver does is it
applies a relaxed, "default" configuration, in which all masters
are trusted for R/W.

Note that some instances of this IP (e.g: AIPSTZ5 on i.MX8MP) may be tied
to a power domain and may lose their configuration when the domain is
powered off. This is why the configuration has to be restored when the
domain is powered on.

firewall: introduce stm32_firewall framework

2024-04-05T14:49:14+00:00

Introduce a STM32 firewall framework that offers to firewall consumers
different firewall services such as the ability to check their access
rights against their firewall controller(s).

The STM32 firewall framework offers a generic API for STM32 firewall
controllers that is defined in their drivers to best fit the
specificity of each firewall.

There are various types of firewalls:
-Peripheral firewalls that filter accesses to peripherals
-Memory firewalls that filter accesses to memories or memory regions
-No type for undefined type of firewall

bus: tegra-aconnect: Update dependency to ARCH_TEGRA

2024-02-16T11:11:47+00:00

Update the architecture dependency to be the generic Tegra
because the driver works on the four latest Tegra generations
not just Tegra210, if you build a kernel with a specific
ARCH_TEGRA_xxx_SOC option that excludes Tegra210 you don't get
this driver.

bus: ti-sysc: Build driver for TI K3 SoCs

2023-08-10T06:21:45+00:00

Allow building ti-sysc also for K3 SoCs. This allows configuring the wkup
domain devices for SYSCONFIG register wake-up events in a generic way.

As this is an interconnect level driver, default to built-in on K3 SoCs
to probe the devices connected to the wkup domain like gpio, uart and
timers.
