[PATCH 5/5] arm64: dts: rockchip: Add the reset lines of the RK3588 VEPU121 cores

[Arun Iyengar via B4 Relay <devnull+aiyengar1990.gmail.com@kernel.org>]

From: Arun Iyengar <aiyengar1990@gmail.com>

Describe the AXI and AHB reset lines of the four VEPU121 JPEG encoder
cores, so that the driver can reset a core that is stuck after a fault
of its IOMMU.

The IOMMU of each core sits in the same register block and is clocked
by the same clocks, so these resets likely cover its bus interface as
well. This relies on the driver not leaving a VPU behind an IOMMU in
reset after remove ("media: verisilicon: Don't hold a VPU behind an
IOMMU in reset after remove").
