From c6e126de43e7d4abfd6cf796b40589db3a046167 Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Thu, 15 May 2014 16:55:24 +0100 Subject: [PATCH] of: Keep track of populated platform devices In "Device Tree powered" systems, platform devices are usually massively populated with of_platform_populate() call, executed at some level of initcalls, either by generic architecture or by platform-specific code. There are situations though where certain devices must be created (and bound with drivers) before all the others. This presents a challenge, as devices created explicitly would be created again by of_platform_populate(). This patch tries to solve that issue in a generic way, adding a "populated" flag for a DT node description. Subsequent of_platform_populate() will skip such nodes (and its children) in a similar way to the non-available ones. This patch also adds of_platform_depopulate() as an operation complementary to the _populate() one. It removes a platform or an amba device populated from the Device Tree, together with its all children (leaving, however, devices without associated of_node untouched) clearing the "populated" flag on the way.
