[PATCH 0/2] arm64: dts: amlogic: meson-sm1-odroid-hc4: fix the SPI NOR

From: Igor Velkov via B4 Relay

Date: Wed Sep 30 2026 - 14:11:22 EST


Two fixes for the SPI NOR flash on ODROID-HC4. Patch 1 lets the flash
probe after a boot from SD past the SPI. Patch 2 lowers the clock to
40 MHz, where reads stop returning corrupted data.

U-Boot takes this device tree from dts/upstream and gets the fixes with
the next sync.
