Subject: [PATCH 2/4] dt-bindings: clock: add binding header for sf21-topcrm
Date: Sun, 17 May 2026 22:12:56 +0800	[thread overview]
Message-ID: <20260517-sf21-topcrm-v1-2-438f2e0513ff@gmail.com> (raw)
In-Reply-To: <20260517-sf21-topcrm-v1-0-438f2e0513ff@gmail.com>

Add the device tree binding header for Siflower SF21A6826/SF21H8898
toplevel clock and reset module. The header covers both clock and
reset IDs provided by the block.
CLK_ETH_REF_P is a clock name that exists in the vendor datasheet.
This clock connects directly to CLK_PCIEPLL_FOUT2 and there's no
clock gate/mux in between. An alias is created for this clock
to make available clock names align with the datasheet.
