From c2573128ad1ff36a7e231799c102be2413a2f756 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 10 Nov 2011 10:57:32 +0000 Subject: [PATCH] spi/s3c64xx: Log error interrupts Although the hardware supports interrupts we're not currently using them at all since for small transfers the overhead is greater than that for busy waiting and for large transfers we have interrupts from the DMA. This means that if the hardware reports an error (especially one which might not stall transfer) we might miss it. Take a first pass at dealing with such errors by enabling the interrupt if we can and logging the errors if they happen. Ideally we'd report the error via the affected transfer but since we're in master mode it's very difficult to trigger errors at present and this code is much simpler.
