Subject: [PATCH v3 0/5] STM32 ETZPC bus controller
Date: Tue, 5 May 2020 09:33:03 +0200 [thread overview]
Message-ID: <20200505073308.22914-1-benjamin.gaignard@st.com> (raw)
STM32 Extended TrustZone Protection controller act like a firewall on the
platform bus. Depending of its configuration devices could be accessible
by the TrustZone, the co-processor or the non-secure world. ETZPC
configuration could evolve at runtime for example to switch a device from
non-secure world to co-processor.
The series introduce 'firewall' helpers to handle the new devices-tree
properties. These properties are not dedicated to ETZPC and will be reused
for STM32 next generation of bus controller.
version 3:
- add description in firewall consumer bindings
- add Linus reviewed-by tag
version 2:
- fix unit name into st,stm32-etzpc.yaml example and DT
