Date: Tue, 2 Dec 2014 18:27:27 +0100 From: Nicolas Ferre <nicolas.ferre@...el.com> To: Arnd Bergmann <arnd@...db.de>, Boris BREZILLON <boris.brezillon@...e-electrons.com>, Alexandre Belloni <alexandre.belloni@...e-electrons.com> CC: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@...osoft.com>, Ludovic Desroches <ludovic.desroches@...el.com>, <linux-arm-kernel@...ts.infradead.org>, <linux-kernel@...r.kernel.org>, Olof Johansson <olof@...om.net>, <arm@...nel.org>, Nicolas Ferre <nicolas.ferre@...el.com> Subject: [PATCH 7/8] pinctrl: at91: add registers definitions directly into driver As the old gpio.c driver is gone, we can merge the registers definitions with the pinctrl driver. This also allows us to empty the AT91 include/mach directory.
