Subject: [PATCH 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.

This series adds support for these extra clocks, which are called
`iface_x`.

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
