10   - Emil Renner Berthing <emil.renner.berthing@canonical.com>
13   Pinmux and pinconf controller in the T-Head TH1520 RISC-V SoC.
17     PADCTRL_AOSYS  -> PAD Group 1
18     PADCTRL1_APSYS -> PAD Group 2
19     PADCTRL0_APSYS -> PAD Group 3
27   strength, input enable, schmitt trigger, slew rate, pull-up and pull-down in
30   Certain pads in group 1 can be muxed to AUDIO_PA0 - AUDIO_PA30 functions and
31   are then meant to be used by the audio co-processor. Each such pad can then
35   AUDIO_IOCTRL memory range and is left to the audio co-processor for now.
