Subject: [U-Boot] [u-boot PATCH v2 1/8] ARM: OMAP5+: GPIO: Add GPIO_TO_PIN() macro
Date: Mon, 30 Jan 2017 17:15:09 +0200 [thread overview]
Message-ID: <1485789316-22216-2-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1485789316-22216-1-git-send-email-rogerq@ti.com>
GPIO_TO_PIN(bank, bank_gpio) returns the GPIO index
from the GPIO bank number and bank's GPIO offset number.
