Subject: [PATCH 1/1] hwspinlock: qcom: fix tcsr data for ipq6018
Date:   Tue, 12 Dec 2023 22:25:09 +0800
Message-Id: <20231212142509.655094-1-amadeus@jmu.edu.cn>

The tcsr_mutex hwlock register of the ipq6018 SoC is 0x20000[1], which
should not use the max_register configuration of older SoCs. This will
cause smem to be unable to probe, further causing devices that use
smem-part to parse partitions to fail to boot.

[    2.118227] qcom-smem: probe of 4aa00000.memory failed with error -110
[   22.273120] platform 79b0000.nand-controller: deferred probe pending

Remove 'qcom,ipq6018-tcsr-mutex' setting from of_match to fix this.
