Arrays are not always expanded resulting in invalid subtype declarations.

Running svd2ada on (for example) https://github.com/espressif/svd/blob/main/svd/esp32s3.svd does not always handle arrays correctly.

Taking the excerpt:

<register>
          <name>INT_RAW</name>
          <description>Raw interrupt status</description>
          <addressOffset>0x70</addressOffset>
          <size>0x20</size>
          <fields>
            <field>

              <dimIncrement>0x1</dimIncrement>
              <dimIndex>0-3</dimIndex>
              <name>CH%s_TX_END</name>
