Subject: [PATCH v2 0/2] arm64: dts: rockchip: NanoPi R2S Plus: fix io-domains, enable SDIO Wi-Fi
Date: Sat, 31 Oct 2026 13:47:12 +0300 [thread overview]
Message-ID: <20261031104714.3271017-1-rojer@rojer.me> (raw)
Patch 1 fixes the VCCIO4/VCCIO6 supplies of the NanoPi R2S Plus, which
were inherited from the NanoPi R2S but are wired differently (see the
schematics referenced in the patch).
Patch 2 enables the M.2 E-key SDIO slot, which FriendlyElec populates
with an optional RTL8822CS (Fn-Link 6222B-SRC) Wi-Fi module.
With these the module works at 50 MHz high-speed. Reaching SDR104 needs
an mmc core fix for the module's CMD11 handling, posted to linux-mmc:
https://lore.kernel.org/linux-mmc/20261030142224.3183407-1-rojer@rojer.me/
Tested on a NanoPi R2S Plus; dtbs_check reports no new warnings.
Changes in v2:
- 2/2: dropped disable-wp from the SDIO node (Shawn).
- 2/2: link to v3 of the mmc series.
- Collected Reviewed-by (Shawn, 2/2).
v1: https://lore.kernel.org/linux-rockchip/20261023235959.2988087-1-rojer@rojer.me/
