comments:
 - we are waiting for physical HW for the developer
 - there will not be extra physical HW
 - 745cdc4ea76af480cb9c4a47f78a580e08ed03b6:
    - register layout probably needs to be converted to regmap
    - regmap conversion could be tested on Gen3 locally and on V3U by Renesas in Japan
    - waiting for budget
    - Ulrich was contracted
    - Ulrich found out that regmap is not suitable but the macros from the BSP can be greatly simplified
 - 745cdc4ea76af480cb9c4a47f78a580e08ed03b6, 236a7d2185b21c46064ccf6ece8905ddda16d5e7:
    - v1; https://lore.kernel.org/r/20210924153113.10046-1-uli+renesas@fpond.eu
    - Renesas Japan cannot test these changes, we have to find our own way
    - discussing with Kieran and Ulrich how to accomplish this
