Subject: [PATCH v4 0/5] STM32 ETZPC bus controller
Date: Fri, 5 Jun 2020 10:33:43 +0200 [thread overview]
Message-ID: <20200605083348.13880-1-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 4:
- use bus API
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
