Subject: [PATCH v5 11/14] soc: qcom: ubwc: Fix SM6125's ubwc_swizzle value
Date: Wed, 25 Jun 2025 15:10:19 +0200	[thread overview]
Message-ID: <20250625-topic-ubwc_central-v5-11-e256d18219e2@oss.qualcomm.com> (raw)
In-Reply-To: <20250625-topic-ubwc_central-v5-0-e256d18219e2@oss.qualcomm.com>

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

The value of 7 (a.k.a. GENMASK(2, 0), a.k.a. disabling levels 1-3 of
swizzling) is what we want on this platform (and others with a UBWC
1.0 encoder).

Fix it to make mesa happy (the hardware doesn't care about the 2 higher
bits, as they weren't consumed on this platform).
