Subject: [PATCH 2/3] dt-bindings: sound: spacemit,k1-i2s: allow 6 clocks for K3 i2s1
Date: Tue, 21 Jul 2026 19:35:56 -0700 [thread overview]
Message-ID: <20260721-kx-i2s-dts-v1-2-d22cb6cfaab5@linux.spacemit.com> (raw)
In-Reply-To: <20260721-kx-i2s-dts-v1-0-d22cb6cfaab5@linux.spacemit.com>
The K3 I2S controllers normally use the published 7-clock layout:
sysclk, bclk, bus, func, sysclk_div, c_sysclk, c_bclk
However, K3 i2s1 has no dedicated sysclk divider and therefore uses a
6-clock layout:
sysclk, bclk, bus, func, c_sysclk, c_bclk
Describe the 4-clock K1 and both K3 layouts as separate tuples. Lower
the K3 minimum from 7 to 6 clocks while preserving the existing
7-clock ordering.
Fixes: 6bc6b28c0314 ("ASoC: dt-bindings: add SpacemiT K3 SoC compatible")
