Subject: [PATCH] arm64: dts: rockchip: add (but disabled) SFC node for Radxa
|
|
ROCK 5A
|
|
|
|
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.
