2026-03-23scmi: Rework SCMI_FIRMWARE implementationTom Rini
As exposed by "make randconfig", how we have SCMI_FIRMWARE today is incomplete, and in one case, used incorrectly. First, SCMI_FIRMWARE has a build-time dependency on OF_CONTROL being enabled, so add that. Second, RESET_SCMI depends on SCMI_FIRMWARE being enabled, it should not select that symbol. In turn, a number of platforms need to now enable SCMI_FIRMWARE explicitly and not rely on RESET_SCMI to enable it for them.

2026-01-09dm: core: Default to using DEVRES outside of xPLTom Rini
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.

2025-04-01Merge patch series "airoha: Add initial support AN7581"Tom Rini
Christian Marangi <[email protected]> says: This little series adds initial support for Airoha AN7581 SoC. With the help of some backport patch, this use OF_UPSTREAM directly. Posting this to have the targer and the very basic driver. Ethernet, SNAND and eMMC support is already ready downstream and will be posted shortly after this gets approved. Having the first driver ready permits to separately push dedicate series for SNAND, eMMC and Ethrnet as they all depends on basic support of clock and reset and nothing else.

2024-01-16clk/qcom: handle resets and clocks in one deviceKonrad Dybcio
Qualcomm's clock controller blocks actually do much more than it says on the tin.. They provide clocks, resets and power domains. Currently, U-Boot requires one to spawn 2 separate devices for controlling clocks and resets, both spanning the same register space. Refactor the code to make it work with just a single DT node, making it compatible with upstream Linux bindings and dropping the dedicated reset driver in favour of including it in the clock driver. Heavily inspired by Renesas code for a similar hw block. [caleb: moved drivers to clk/qcom, added reset driver and adjusted bind logic.

2018-09-11reset: Introduce TI System Control Interface (TI SCI) reset driverAndreas Dannenberg
Some TI Keystone 2 and K3 family of SoCs contain a system controller (like the Power Management Micro Controller (PMMC) on 66AK2G SoCs and the Device Management and Security Controller on AM65x SoCs) that manage the low-level device control (like clocks, resets etc) for the various hardware modules present on the SoC. These device control operations are provided to the host processor OS through a communication protocol called the TI System Control Interface (TI SCI) protocol. This patch adds a reset driver that communicates to the system controller over the TI SCI protocol for performing reset management of various devices present on the SoC. Various reset functionalities are achieved by the means of different TI SCI device operations provided by the TI SCI framework. This code is loosely based on the drivers/reset/reset-ti-sci.c driver of the Linux kernel.
