[PATCH 0/5] ti: fix dtbs_check for some syscon bindings and DTS node

[PATCH 0/5] ti: fix dtbs_check for some syscon bindings and DTS node

[Krzysztof Kozlowski]

Hi,

I am in the process of fixing syscon/simple-mfd bindings (to be posted
separately) and found set of issues in TI looking independent of my
series.  Please apply via TI SoC.

Best regards,
Krzysztof

Add dedicated binding for AM62 and AM62A wakeup system controller
registers, already used in the DTS to properly describe their children.

[PATCH 3/5] arm64: dts: ti: k3-am62: add dedicated wakeup controller compatible

is also reported by dtbs_check:

  k3-am62-lp-sk.dtb: syscon@43000000: compatible: ['syscon', 'simple-mfd'] is too short

Add one for the TI K3 AM62 wakeup system controller.

Each syscon node must come with a dedicated/specific compatible, which
is also reported by dtbs_check:

  k3-am654-base-board.dtb: scm-conf@40f00000: compatible: ['syscon', 'simple-mfd'] is too short

Add one for the TI K3 AM654 MCU wakeup system controller.

[PATCH 5/5] arm64: dts: ti: k3-am62a: use a specific MCU controller compatible

[Krzysztof Kozlowski]

SoCs (and associated MCUs) should use dedicated compatibles for their
nodes, not re-use one coming from an another SoC.  Using an incorrect
compatible does not allow to properly match/validate children of the
MCU device and causes dtbs_check warnings:

  k3-am62a7-sk.dtb: syscon@43000000: 'syscon@4008', 'syscon@4018' do not match any of the regexes:
    '^chipid@[0-9a-f]+$', '^clock-controller@[0-9a-f]+$', '^mux-controller@[0-9a-f]+$', 'phy@[0-9a-f]+$', 'pinctrl-[0-9]+'

Good to see progress here! Helps us finding our own issues while adding 
things to the affected targets.

But you didn't address this ones yet:

.../arch/arm64/boot/dts/ti/k3-am654-base-board.dtb: scm-conf@100000: compatible: ['syscon', 'simple-mfd'] is too short
        from schema $id: http://devicetree.org/schemas/mfd/syscon.yaml#
(plus our IOT2050 boards, all via k3-am65-main.dtsi)

And a number of other boards seem to lack adoption of the new wakeup 
controller binding if I get this correctly:

.../arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dtb: syscon@40f00000: compatible: ['syscon', 'simple-mfd'] is too short

There are just too many warnings to be fixed.
