From 2fb1f7d29932db2908bdaad0f03c326e800d5e62 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 9 Jun 2020 14:23:16 +0200 Subject: arm/stm32f405: Fix realization of "stm32f2xx-adc" devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit stm32f405_soc_initfn() creates six such devices, but stm32f405_soc_realize() realizes only one. Affects machine netduinoplus2. In theory, a device becomes real only on realize. In practice, the transition from unreal to real is a fuzzy one. The work to make a device real can be spread between realize methods (fine), instance_init methods (wrong), and board code wiring up the device (fine as long as it effectively happens on realize). Depending on what exactly is done where, a device can work even when we neglect to realize it. The five unrealized devices appear to stay unreal: neither MMIO nor IRQ get wired up. Fix stm32f405_soc_realize() to realize and wire up all six.
