2022-06-21lib: utils/timer: Add a separate compatible for the D1 CLINTSamuel Holland
The CLINT in the Allwinner D1 SoC apparently does not support 64-bit MMIO access. A property was added to support this quirk (and that property was copied to the ACLINT MTIMER code). However, since this difference in behavior makes the D1 CLINT incompatible with the SiFive CLINT's programming interface, a better solution is to use a separate compatible string.

2021-10-21lib: utils/irqchip: Automatically delegate T-HEAD PLIC accessSamuel Holland
The T-HEAD PLIC implementation requires setting a delegation bit to allow access from S-mode.
