Subject: [patch 3/4] spi_s3c24xx_gpio: fix setting of num_chipselect.
Date: Fri, 10 Oct 2008 11:04:31 +0100 [thread overview]
Message-ID: <20081010100455.281564467@fluff.org.uk> (raw)
In-Reply-To: 20081010100428.047162446@fluff.org.uk
[-- Attachment #1: simtec/simtec-s3c24xx-spi-gpio-fix-numcs.patch --]
[-- Type: text/plain, Size: 1959 bytes --]
The spi master driver must have num_chipselect set to
allow the bus to initialise. Pass this through the
platform data.
