Subject: [PATCH v2 0/2] Fix tcsr_mutex register for IPQ6018

IPQ6018 has 32 tcsr_mutex hwlock registers of 0x1000 size each.
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.

This series fixes the following:
 1. Fix the tcsr_mutex register size to 0x20000 in IPQ6018 DTSI.
 2. Remove IPQ6018 specific compatible in hwspinlock driver so that it
    falls back to pick of_tcsr_mutex data.

Changes in v2:
 - Drop changes to remove qcom,ipq6018-tcsr-mutex from dt-bindings
 - Drop changes to remove qcom,ipq6018-tcsr-mutex compatible from
   ipq6018.dtsi
 - Add Fixes and stable tags
