From 112485e9c543b17fc08daea56c7a558b415d06af Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Mon, 16 Aug 2010 10:55:35 +0200 Subject: OMAP: mux: Add support for control module split in several partitions Starting on OMAP4, the pin mux configuration is located in two different partitions of the control module (CODE_PAD and WKUP_PAD). The first one is inside the core power domain whereas the second one is inside the wakeup. - Add the capability to add any number of partition during board init time depending of Soc partitioning. - Add some init flags as well in order to avoid explicit Soc version check inside the mux core code. - Add a comment with mux0 mode on top of omap_mux/board/ if the current mux mode is not the default one. Thanks to Tony Lindgren for the following improvements: - Add omap_mux_get for getting the partition data so platform level device code can use it. - Fix the rx51 board code to use the new API. - Do not store the partition for each mux entry. Look up the partition for debugfs instead. Thanks to Dan Murphy for testing on OMAP4 and reporting a couple of bugs. Thanks to Anand Gadiyar for testing on OMAP3 zoom and bug report.
