Subject: [RFC/DRAFT] SPI OF bindings, MMC-over-SPI, chip-selects and so on
Date: Wed, 21 May 2008 19:41:03 +0400 [thread overview]
Message-ID: <20080521154103.GA32577@polina.dev.rtsoft.ru> (raw)
Hi all,
This is just a bait for further discussion of OF/SPI, chip-selects,
e.t.c.
I've converted the spi_mpc83xx to the OF driver (using Grant's
SPI_MASTER_OF work + some additions), and implemented MMC-over-SPI
bindings. This stuff extensively using GPIOs, and I think this will
work for the "bridged SPI" too, since the SPI bridge could be
represented as GPIO controller (inside the SPI controller node).
Thoughts?
