Quad and Dual format support for Synopsys Enhanced SPI controllers

charkster opened this issue · comments

I have a new Raspberry Pi 5 board and their documentation says that SPI0 can be quad format. The RPi5 SPI master is a Synopsys SSI, which has "enhanced" features such as Quad and Dual width. I have seen the Linux kernel changes for this particular controller and was wondering if you had plans to support it in py-spidev? Single width is default for SPI0 and it works just fine with py-spidev.
Thanks.
