Subject: [PATCH v2 0/2] iommu/rockchip: Add support for multiple interface clocks

From: Chaoyi Chen <chaoyi.chen@...k-chips.com>

Hi,

Some rockchip iommus require extra clocks besides aclk and interface
clock, such as the iommus for NPU and RKVENC in RK3576.

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20251126083345.88-1-kernel@airkyi.com/
- Rewrite dt binding.

Chaoyi Chen (2):
  dt-bindings: iommu: rockchip: Add support for multiple interface
    clocks
  iommu/rockchip: Use devm_clk_bulk_get_all() to get multiple iface
    clock
