Message-Id: <1455637261-2920972-5-git-send-email-arnd@arndb.de> Date: Tue, 16 Feb 2016 16:40:38 +0100 From: Arnd Bergmann <arnd@...db.de> To: Linus Walleij <linus.walleij@...aro.org> Cc: linux-arm-kernel@...ts.infradead.org, Arnd Bergmann <arnd@...db.de>, Russell King <rmk+kernel@....linux.org.uk>, Bjorn Helgaas <bhelgaas@...gle.com>, Alexandre Courbot <gnurou@...il.com>, linux-gpio@...r.kernel.org, linux-kernel@...r.kernel.org, Lars-Peter Clausen <lars@...afoo.de>, Ralf Baechle <ralf@...ux-mips.org>, linux-mips@...ux-mips.org, linux-arch@...r.kernel.org Subject: [PATCH v2 5/5] gpio: allow setting ARCH_NR_GPIOS from Kconfig The ARM version of asm/gpio.h basically just contains the same definitions as the gpiolib version, with the exception of ARCH_NR_GPIOS. This adds the option for overriding the constant through Kconfig to the architecture-independent header, so we can remove the ARM specific file later.
