Amlogic Meson SoC platform support (canvas, clock-measure, SoC ID)
Low-level platform glue for Amlogic's Meson family of ARM systems-on-chip — the GX, AXG, A1, T7 and similar parts found in Android TV boxes, set-top boxes, HDMI streaming dongles, and single-board computers like the Khadas and Odroid lines. It handles SoC identification, the Meson display "canvas" memory regions, and a debug interface for measuring on-chip clocks.
recommendation
It should stay in the kernel because Amlogic's Meson chips are still actively shipping in 2025 in Android TV boxes, OTT streamers, and HDMI dongles, and upstream work continues into 2026 — including new clock-measurement support for the A1 and T7 parts and SoC identification for the recent S905Y4. These files provide chip-specific plumbing (display canvas, debug clock measurement, SoC-ID readout) that has no generic replacement.

codex reasoning notes (technical)
Local inspection via exec_command shows this is real driver code: canvas IP, debugfs clock-measure, and Meson SoC-identification drivers. lore_file_timeline MCP showed active upstream attention through 2026-04-21 (clk-measure A1/T7 support) and 2026-01-13 (new S905Y4 SoC ID), with no credible removal signal; a broader lore_subsystem_churn query returned a lore coverage blind spot, and one lore_regex removal scan timed out rather than producing evidence. Web sources were obtained via web search and show Meson-family parts still shipping in current TV/OTT products. No natural replacement exists because these files provide SoC-specific identification/debug/canvas plumbing rather than a superseded functional class.
