Re: [PATCH v2] fpga: microsemi-spi: add Microsemi FPGA manager

Hey Ivan,
Firstly thanks for the patch(es), stumbled across them today.
As you may know Microsemi has been acquired by Microchip, so
s/microsemi/microchip/ please. This would make the correct vendor
prefix for compatible strings "microchip". While you've said this is
for the PolarFire FPGA, there is prescendent for using "mpfs" for the
PolarFire SoC FPGA in the kernel - so if you could change the uses of
"polarfire" to "mpf" that'd be great.

The current item on my own todo list is the opposite side of this,
reprogramming the FPGA via the system controller acting as a SPI
master for PolarFire SoC.
I will get back to you when I have a better idea of what (if any) code
can be made generic between both modes. In the meantime, I will get
together a setup to test SPI slave reprogramming of the PolarFire (SoC)

Thanks,
Conor <conor.dooley@xxxxxxxxxxxxx>
