From 2ed86b16eabe4efbf80cc725a8cbb5310746a2fc Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 25 Jan 2012 20:02:40 -0600 Subject: [PATCH] irq: make SPARSE_IRQ an optionally hidden option On ARM, we don't want SPARSE_IRQ to be a user visible option. Make SPARSE_IRQ visible based on MAY_HAVE_SPARSE_IRQ instead of depending on HAVE_SPARSE_IRQ. With this, SPARSE_IRQ is not visible on C6X and ARM.
