This converts the clint driver from the riscv-specific interface to be a DM-based UCLASS_TIMER driver. In addition, the SiFive DDR driver previously implicitly depended on the CLINT to select REGMAP. Unlike Andes's PLMT/PLIC (which AFAIK never have anything pass it a dtb), the SiFive CLINT is part of the device tree passed in by qemu. This device tree doesn't have a clocks or clock-frequency property on clint, so we need to fall back on the timebase-frequency property. Perhaps in the future we can get a clock-frequency property added to the qemu dtb. Unlike with the Andes PLMT, the Sifive CLINT is also an IPI controller. RISCV_SYSCON_CLINT is retained for this purpose. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Pragnesh Patel <pragnesh.patel@openfive.com> |
