Subject: [PATCH] arm64: dts: rockchip: rk3399-pinebook-pro: cap spi1 to 10 MHz
|
|
|
|
The on-board SPI flash on the Pinebook Pro is reachable via spi1; setting
|
|
spi-max-frequency below the controller's nominal max keeps the bus stable
|
|
across the variants of NOR flash shipped with the laptop. 10 MHz is the
|
|
community-validated upper bound that all observed parts handle without
|
|
read-back errors during routine boot probes.
