From dbd897b9c6fac8bcb38e378e12c2790f293ae1fe Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 23 May 2013 19:46:40 +0200 Subject: [PATCH] spi: pl022: use DMA by default when probing from DT In the past we controlled the selection of DMA for a certain host by a boolean switch in the platform data. Currently there is no way to enable DMA on a PL022 probed from the device tree. Let's default to trying to obtain DMA channels in the DT case, and then we can always fail (and thus fall back to PIO mode).
