Subject: [PATCH 07/11] ARM: dts: turris-omnia: Add MCU system-controller node
|
|
MIME-Version: 1.0

Turris Omnia's MCU provides various features that can be configured over
|
|
I2C at address 0x2a. Add device-tree node.
|
|
|
|
This does not carry a Fixes tag - we do not want this to get backported
|
|
to stable kernels for the following reason: U-Boot since v2022.10
|
|
inserts a phy-reset-gpio property into the WAN ethernet node pointing to
|
|
the MCU node if it finds the MCU node with a cznic,turris-omnia-mcu
|
|
compatible. Thus if this change got backported to a stable kernel, the
|
|
WAN interface driver would defer probe indefinitely (since it would wait
|
|
for the turris-omnia-mcu driver which would not be present).
