Subsystems (2)
PATCH v3 1/1 arm64: dts: stratix10: Add QSPI support for Stratix10
From: Thor Thayer <[email protected]>
Add qspi_clock
The qspi_clk frequency is updated by U-Boot before starting Linux.
Add QSPI interface node.
Add QSPI flash memory child node.
Setup the QSPI memory in 2 partitions.
---
v2 s/_/-/ in qspi-clk
rename flash node.
use partition child node notation
v3 remove unused bus-num node
use device id from table (n25q00a)
