Linux 5.10 Changelog for the Arm architecture
- ARM64 – ARM Memory Tagging Extension – Memory Tagging Extension (part of the ARMv8.5 Extensions) provides a mechanism to detect the sources of memory-related errors that may be vulnerable to exploitation, including bounds violations, use-after-free, use-after-return, use-out-of-scope, and use before initialization errors.

- ARM64 DTS updates for Linux 5.10
- Cleanup, refactor and modernize MSM8916 by sorting nodes, moving device and platform-specific parts to their respective files, add and use labels for reference nodes and use IRQ defines. Migrate TCSR mutex off the deprecated binding, add resin node for PM8916.
- Add LPASS clock controller for SC7180. Fix the LLCC reg, increase interconnect-cells, drop flags on MDSS irqs. Add interconnects for display, eMMC and SD-card, specify ‘sustainable_power’ for CPU thermal zones, improve pinconf states related to UART and Bluetooth. Add new DT for Lazor and Trogdor.
- Increase #interconnect-cells for SDM845 to allow tags, add OPP tablesand power-domains for Venus and interconnects for display. Fix the ports on the HDMI nodes for DB845c and add DT for the Xiaomi Poco F1.
- Add interconnect providers, fix up primary USB’s clock and use dt-binding defines for GPU clocks on SM8150.
- Add interconnect providers, CPUfreq, thermal configuration and missing uarts for SM8250. Fix up naming of debug uart, add always-on supply clock to gcc, fix up the sleep clock rate and define OPP tables for all QUP devices. Then add a new DeviceTree for the QRB5165 RB5 board.
- Enable watchdog on IPQ8074 and use the appropriate compatible for the PMU node. Enable DVFS support for IPQ6018.
- Correct the spelling of “interrupts” in MSM8992 uart node, fix missing # in PM660 #interrupt-cells, add second VFE power-domain to camss in MSM8996 and sort the Makefile.
