Is Hexa-SPI (HSPI) found in STM32U5 family supported?

[ivanwagner]

Dear all,

I looked within the dts structure of the STM32U5 family and cannot see any definition for the HSPI registers. Is someone working on it or will it be supported?

Hello @ivanwagner,
Hexa-SPI is not supported by any stm32 device.
Moving to the zephyr MSPI is probably a interesting approach (instead of adding a new stm32 driver), but coming after single/quad/octo modes.

Thank you for the answer. I took a look at MSPI. What about adding the missing registers for the HSPI peripheral on the STM32U5 device? That is something that needs to be done in any case, correct?

Sure, adding the hspi peripheral to the devices DTS and to the board, including the pin definition, is required in any case.
