Subject: [PATCH v2 1/2] ASoC: dt-bindings: add SpacemiT K3 SoC compatible
Date: Thu, 07 May 2026 15:33:09 +0800 [thread overview]
Message-ID: <20260507-k3-i2s-v2-1-9cdbf95b7533@linux.spacemit.com> (raw)
In-Reply-To: <20260507-k3-i2s-v2-0-9cdbf95b7533@linux.spacemit.com>
Add the spacemit,k3-i2s compatible string for the K3 SoC I2S
controller. The K3 I2S IP is the same as K1 but requires additional
clocks: a dedicated sysclk_div clock, along with common_sysclk and
common_bclk which are shared across multiple I2S controllers on K3.
Acked-by: Rob Herring (Arm) <robh@kernel.org>
