From 9ed7a776eb50de2284dd053c719f2f6481af9027 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 3 Nov 2014 17:45:01 -0800 Subject: [PATCH] ARM: OMAP2+: Fix support for multiple devices on a GPMC chip select There are cases where we have multiple device instances connected to a single GPMC chip select. For example, there are four UARTs on the Zoom debug boards that all share a single chip select and a GPIO interrupt. We do have support for this already in theory, but it's broken because we're bailing out if the chip select is already taken. To be able to provide checks on the chip select usage, let's add new struct gpmc_cs_data so we can start using already registered device names for checks. Later on we probably want to start using struct gpmc_cs_data as a wrapper for all the GPMC chipselect related data.
