Subject: [PATCH v3 0/3] arm64: dts: allwinner: add A733/Cubie A7S support
Date: Mon, 9 Nov 2026 23:45:15 -0500 [thread overview]
Message-ID: <cover.1794227241.git.enzo.adriano.code@gmail.com> (raw)
This series adds the initial Allwinner A733 and Radxa Cubie A7S device
trees, enabling UART0, the AXP318W PMIC and the 3.3 V microSD path.
Base: v7.4-rc1 (6628e7d4c6b25c8d18f1345e3a20d21829aae7e4).
Previous posting (v2):
https://lore.kernel.org/r/20261031020640-263f7b05-a7s-dt-v2-0@gmail.com
Changes in v3:
- Defer SMHC3/mmc3 until it has a tested user; omit binding, node and pins.
- Rebase on v7.4-rc1 and list public schema prerequisites.
Dependencies, in application order:
[1] A733 CCU v6:
https://lore.kernel.org/r/20261009-a733-clk-v6-0-ae8178fce7e8@pigmoral.tech
[2] AXP318W PMIC v8:
https://lore.kernel.org/r/20260910-axp318-regulator-v8-0-e906a61a7f3d@baylibre.com
[3] Pinctrl IRQ-bank v3:
https://lore.kernel.org/r/20261025142412.112216-1-pmazzini@gmail.com
[4] A733 8250_dw v2, patches 2-4:
https://lore.kernel.org/r/cover.1792439398.git.vinicius.eduardo.pedrosa@gmail.com
[5] Firmware clocks (separate from CCU v6):
https://lore.kernel.org/r/20261031020640-263f7b05-a7s-clock@gmail.com
[6] Pinctrl voltage-mode fix v3:
https://lore.kernel.org/r/20261109-a733-pinctrl-v3@gmail.com
DTB/schema checks need only [1] 1/8, [2] 3/5, [3] 2/3 and [4] 3/4,
applied in that order before this series. Runtime needs the full CCU,
PMIC and IRQ-bank series, [4] patches 2-4, and [5]-[6]. The clock helpers
listed in v2 are already in v7.4-rc1.
Validation: arm/sunxi.yaml schema check, W=2 CHECK_DTBS=y DTB build
and clean git-am reader test passed. The November 4 DT v2 RAM boot
exercised UART0, PMIC and MMC0 reads on Cubie A7S with vendor firmware
and pinctrl v2; v3 removes a disabled controller and unused pin group.
Untested: boot with pinctrl v3, card writes, hotplug, 1.8 V switching,
other UART/I2C and storage instances, RTC alarms, EL2/ITS/MSI, and
physical BLDO2 voltage.
