+Subject: [PATCH] hwspinlock: qcom: Remove IPQ6018 SOC specific compatible
+
+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.
+
+Fixes: 5d4753f741d8 ("hwspinlock: qcom: add support for MMIO on older SoCs")
