[PATCH 0/2] riscv: dts: anlogic: dr1v90: fix clock dtbs_check errors

[Junhui Liu]

The external CAN and watchdog clocks are optional board-level inputs to
the DR1V90 CRU. The current binding requires both inputs, causing the
common SoC device tree to provide fixed-clock placeholders without the
required clock-frequency property. Consequently, dtbs_check reports:

arch/riscv/boot/dts/anlogic/dr1v90-mlkpai-fs01.dtb: clock-ext-can (fixed-clock): 'clock-frequency' is a required property
	from schema $id: http://devicetree.org/schemas/clock/fixed-clock.yaml
arch/riscv/boot/dts/anlogic/dr1v90-mlkpai-fs01.dtb: clock-ext-wdt (fixed-clock): 'clock-frequency' is a required property
	from schema $id: http://devicetree.org/schemas/clock/fixed-clock.yaml

Make the external clocks optional in the binding, then remove the unused
placeholders from the common device tree. Both muxes select their internal
clock parents after reset, so boards without the external inputs continue
to operate normally. Boards that route either input can describe the
corresponding clock in their board-level device tree.

This based on linux-next (next-20261001).
