dt-bindings: sram: Document qcom,hawi-imem compatible

2026-04-13T20:01:26+00:00

On Qualcomm Hawi platform, IMEM is a block of SRAM shared across multiple IP blocks which can fall back to "mmio-sram". Document its compatible.

dt-bindings: sram: Allow multiple-word prefixes to sram subnode

Currently, foo-sram is allowed, but foo-bar-sram is not. Allow it so that more complex names aren't unnecessarily simplified.

dt-bindings: sram: qcom,imem: Allow modem-tables subnode

2026-03-04T01:22:14+00:00

The IP Accelerator hardware/firmware owns a sizeable region within the IMEM, named 'modem-tables', containing various packet processing configuration data. It's not actually accessed by the OS, although we have to IOMMU-map it with the IPA device, so that presumably the firmware can act upon it. Allow it as a subnode of IMEM.
