Subject: [PATCH v2 2/2] hwspinlock: qcom: Remove IPQ6018 SOC specific compatible
Date: Tue, 5 Sep 2023 15:25:35 +0530 [thread overview]
Message-ID: <20230905095535.1263113-3-quic_viswanat@quicinc.com> (raw)
In-Reply-To: <20230905095535.1263113-1-quic_viswanat@quicinc.com>
IPQ6018 has 32 tcsr_mutex hwlock registers with stride 0x1000.
The compatible string qcom,ipq6018-tcsr-mutex is mapped to
of_msm8226_tcsr_mutex which has 32 locks configured with stride of 0x80
and doesn't match the HW present in IPQ6018.
Remove IPQ6018 specific compatible string so that it fallsback to
of_tcsr_mutex data which maps to the correct configuration for IPQ6018.
Changes in v2:
- Updated commit message
- Added Fixes and stable tags
Cc: stable@vger.kernel.org
Fixes: 5d4753f741d8 ("hwspinlock: qcom: add support for MMIO on older SoCs")
