[Qemu-arm] [PATCH 06/21] aspeed/timer: Add AST2600 support |
Date: |
Thu, 19 Sep 2019 07:49:47 +0200 |
The AST2600 timer has a third control register that is used to
implement a set-to-clear feature for the main control register.
On the AST2600, it is not configurable via 0x38 (control register 3)
as it is on the AST2500.
Based on previous work from Joel Stanley.
