   4 Subject: [PATCH] hwspinlock: qcom: Remove IPQ6018 SOC specific compatible
   5
   6 IPQ6018 has 32 tcsr_mutex hwlock registers with stride 0x1000.
   7 The compatible string qcom,ipq6018-tcsr-mutex is mapped to
   8 of_msm8226_tcsr_mutex which has 32 locks configured with stride of 0x80
   9 and doesn't match the HW present in IPQ6018.
  10
  11 Remove IPQ6018 specific compatible string so that it fallsback to
  12 of_tcsr_mutex data which maps to the correct configuration for IPQ6018.

  14 Fixes: 5d4753f741d8 ("hwspinlock: qcom: add support for MMIO on older SoCs")
