With the conversion of syscon.yaml minItems for compatibles was set to 2. Current Rockchip dtsi files only use "syscon" for QoS registers. Add Rockchip QoS compatibles to reduce notifications produced with: make ARCH=arm dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/mfd/syscon.yaml make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/mfd/syscon.yaml Signed-off-by: Johan Jonker <jbx6244@gmail.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

title: System Controller Registers R/W Device Tree Bindings
|
|
|
|
description: |
|
|
System controller node represents a register region containing a set
|
|
of miscellaneous registers. The registers are not cohesive enough to
|
|
represent as any specific type of device. The typical use-case is
|
|
for some other node's driver, or platform-specific code, to acquire
|
|
a reference to the syscon node (e.g. by phandle, node path, or
|
|
search using a specific compatible value), interrogate the node (or
|
|
associated OS driver) to determine the location of the registers,
|
|
and access the registers directly.
