Subject: propper support of 5 wire SPI (SPI_READY signal)
Date: Fri, 19 Feb 2016 10:08:46 +0100	[thread overview]

Hallo all,

i'm working on a project which depends on 5 Wire SPI communication. It
is probably identical to spi-davinci.c with SPI_READY signal. Only
difference is that SPI_READY is not supported by hardware, in this case
GPIO input is used.

Currently this project implements SPI_READY and CS on top of spidev
driver. What makes it really ugly, slow and complicated.

My question is, are there any better, upstreamable way to implement it?
For example directly insight of spi framework? Any suggestions and
comments are welcome.

Regards,
Oleksij
