Subject: [PATCH v5 0/4] add TCB driver for sama5d2
Date: Fri, 4 Mar 2022 12:05:36 +0100 [thread overview]
Message-ID: <20220304110540.132520-1-clement.leger@bootlin.com> (raw)
When booting under OP-TEE, the SYSC is secured which means the PIT is
also not accessible by non-secure world. The TCB 0 however is always
available for non-secure world and thus can be used.
This series add a TCB driver and enables it in sama5d2 configs.

Changes in v5:
- Fixed missing include in .dts file for IRQ defines
- Add aic interrupt controller node to avoid DTC warnings
Changes in v4:
- Add missing interrupts property to tcb node
Changes in v3:
- Remove useless defines
- Add printf in case of unsupported timers specified in device-tree
- Add "syscon" compatible to tcb node
Changes in v2:
- Reworked driver to use existing Linux bindings
