Message-ID: <1434647449-5393-1-git-send-email-vitalya@ti.com> Date: Thu, 18 Jun 2015 13:10:49 -0400 From: Vitaly Andrianov <vitalya@...com> To: <linus.walleij@...aro.org>, <gnurou@...il.com>, <linux-kernel@...r.kernel.org>, <linux-gpio@...r.kernel.org> CC: Vitaly Andrianov <vitalya@...com>, Reece Pollack <x0183204@...com> Subject: [PATCH] gpio/davinci: add interrupt support for GPIOs 16-31 Interrupts for GPIOs 16 through 31 are enabled by bit 1 in the "binten" register (offset 8). Previous versions of GPIO only used bit 0, which enables GPIO 0-15 interrupts.
