dt-bindings: interconnect: qcom: Drop QPIC_CORE IDs

2025-10-31T00:48:50+00:00

As like other SDX targets, SDX75 QPIC BCM resource is also modeled as a RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also described as an interconnect node mistakenly. Hence, drop the QPIC interconnect IDs and let the clients use clk-rpmh driver to vote for this resource. Even though this change is an ABI break, it is necessary to avoid describing the same resource provider in two different drivers, as it may lead to votes from clients overriding each other.

dt-bindings: clock: qcom: Add NSS clock controller for IPQ5424 SoC

2025-10-22T21:57:22+00:00

NSS clock controller provides the clocks and resets to the networking blocks such as PPE (Packet Process Engine) and UNIPHY (PCS) on IPQ5424 devices. Add support for the compatible string "qcom,ipq5424-nsscc" based on the existing IPQ9574 NSS clock controller Device Tree binding. Additionally, update the clock names for PPE and NSS for newer SoC additions like IPQ5424 to use generic and reusable identifiers "nss" and "ppe" without the clock rate suffix. Also add master/slave ids for IPQ5424 networking interfaces, which is used by nss-ipq5424 driver for providing interconnect services using icc-clk framework.

Pull Char/Misc/IIO/Binder updates from Greg KH: "Here is the big set of char/misc/iio and other driver subsystem changes for 6.18-rc1. Loads of different stuff in here, it was a busy development cycle in lots of different subsystems, with over 27k new lines added to the tree. Included in here are: - IIO updates including new drivers, reworking of existing apis, and other goodness in the sensor subsystems - MEI driver updates and additions - NVMEM driver updates - slimbus removal for an unused driver and some other minor updates - coresight driver updates and additions - MHI driver updates - comedi driver updates and fixes - extcon driver updates - interconnect driver additions - eeprom driver updates and fixes - minor UIO driver updates - tiny W1 driver updates But the majority of new code is in the rust bindings and additions, which includes: - misc driver rust binding updates for read/write support, we can now write "normal" misc drivers in rust fully, and the sample driver shows how this can be done. - Initial framework for USB driver rust bindings, which are disabled for now in the build, due to limited support, but coming in through this tree due to dependencies on other rust binding changes that were in here. I'll be enabling these back on in the build in the usb.git tree after -rc1 is out so that developers can continue to work on these in linux-next over the next development cycle. - Android Binder driver implemented in Rust. This is the big one, and was driving a huge majority of the rust binding work over the past years. Right now there are two binder drivers in the kernel, selected only at build time as to which one to use as binder wants to be included in the system at boot time. The binder C maintainers all agreed on this, as eventually, they want the C code to be removed from the tree, but it will take a few releases to get there while both are maintained to ensure that the rust implementation is fully stable and compliant with the existing userspace apis.

The CPU core in ipq5424 is clocked by a huayra PLL with RCG support. The RCG and PLL have a separate register space from the GCC. Also the L3 cache has a separate pll and needs to be scaled along with the CPU.
