Subject: [PATCH RFC RFT v2 1/3] dt-bindings: clock: amlogic: Add PLL pre-divider clock IDs
Date: Thu, 29 Oct 2026 17:30:52 +0800	[thread overview]
Message-ID: <20261029-meson_refactor_n-v2-1-ff4ac74e527b@amlogic.com> (raw)
In-Reply-To: <20261029-meson_refactor_n-v2-0-ff4ac74e527b@amlogic.com>

From: Jian Hu <jian.hu@amlogic.com>

Add clock IDs for the PLL pre-divider clocks. These IDs are
required for the subsequent conversion of the PLL pre-divider
into a standalone divider clock following the PLL framework refactoring.

Signed-off-by: Jian Hu <jian.hu@amlogic.com>
