From a3323b72b964471650a6128de4e10f8e88d47ae1 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 3 Nov 2009 14:42:04 +0000 Subject: ARM: SMDK6410: Configure GPIO pull up for WM835x IRQ line When used with the WM1190-EV1 board we can use the internal pull up resistor of the CPU to provide the required pull for the IRQ line. Without this interrupts from the WM835x don't work in the default WM1190-EV1 hardwaer configuration.

No option is currently supported for running without a PMIC card, the assumption is that the regulator API will be built out when no soft PMIC card is in use. To ease merge issues since this uses the newly added dev_name supply configuration from the regulator API (currently in -next only) the fixed voltage regulator is ifdefed out when the regulator API is not enabled.
