Message-ID: <1305967324-16440-1-git-send-email-linus.walleij@stericsson.com> Date: Sat, 21 May 2011 10:42:04 +0200 From: Linus Walleij <linus.walleij@...ricsson.com> To: Samuel Ortiz <sameo@...ux.intel.com>, <linux-kernel@...r.kernel.org> Cc: Lee Jones <lee.jones@...aro.org>, Rabin Vincent <rabin.vincent@...ricsson.com>, Linus Walleij <linus.walleij@...aro.org> Subject: [PATCH 03/13] mach-ux500: update SoC and board IRQ handling From: Rabin Vincent <rabin.vincent@...ricsson.com> This splits out a per-SoC IRQ range handling, so that the DB8500 and DB5500 SoC:s can reuse aproximately the same IRQ range with the largest span setting the roof. The same change is done for the boards, mutatis mutandis, with a new file for the U5500 board.
