From fe39f2f4dc8481d3aa4561ba649b0c0a4429a49e Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Tue, 13 Nov 2012 19:18:07 +0530 Subject: [PATCH] mfd: Implement tps6586x gpio_to_irq The TPS6586x adds the interrupt of this device using linear mapping on irq domain. Hence, implement gpio_to_irq to get the irq number corresponding to TPS6586x GPIOs which is created dynamically.
