Subject: [PATCH 2/3] arm64: dts: rockchip: add (but disabled) SFC node for Radxa ROCK 5A
Date: Sun, 23 Jun 2024 11:33:28 +0900 [thread overview]
Message-ID: <20240623023329.1044-2-naoki@radxa.com> (raw)
In-Reply-To: <20240623023329.1044-1-naoki@radxa.com>
This commit adds SFC node for Radxa ROCK 5A.
since sdhci and sfc on RK3588s share pins(i.e. exclusive), it cannot
be enabled both nodes at the same time. so status = "okay" is omitted
here.
you may be able to enable sfc (and disable sdhci) by fdt overlay.
SPI NOR flash chip may vary, so use safe(lowest) spi-max-frequency.
