Subject: [PATCH 0/4] hwspinlock: qcom: Allow dropping the intermediate TCSR mutex syscon
Date: Tue, 12 May 2020 17:54:37 -0700 [thread overview]
Message-ID: <20200513005441.1102586-1-bjorn.andersson@linaro.org> (raw)
In all modern Qualcomm platforms the mutex region of the TCSR is forked
off into its own block, all with a offset of 0 and stride of 4096.
Update the binding to allow the hardware block to be described directly
on the mmio bus, in addition to allowing the existing syscon based
definition.
