Subject: [PATCH v2 8/8] arm64: dts: qcom: qcs404: Add fastrpc nodes
Date: Thu, 9 May 2019 21:34:21 -0700 [thread overview]
Message-ID: <20190510043421.31393-9-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20190510043421.31393-1-bjorn.andersson@linaro.org>
From: Thierry Escande <thierry.escande@linaro.org>
The ADSP fastrpc provides 3 context banks and are assigned to IOMMU
context banks 23, 24 and 25; using SIDs 0x804, 0x805 and 0x806. The
CDSP fastrpc provides 5 context banks and are assigned to IOMMU context
banks 5, 6, 7, 8 and 9; using SIDs 0x1001 through 0x1005. Add these to
their respective remoteproc.
The lower 4 bits of the SID is used to identify the context bank when
communicating with the fastrpc firmware, so this gives the reg values.
