From c39dc960e9c5196022cbc46507d4782b6fc314f6 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 23 Oct 2015 12:16:42 +0300 Subject: [PATCH] mfd: intel_quark_i2c_gpio: load gpio driver first On Intel Galileo boards the GPIO expander is connected to i2c bus. Moreover it is able to generate interrupt, but interrupt line is connected to GPIO. That's why we have to have GPIO driver in place when we will probe i2c host with device connected to it.
