From 14c251ffe156e5b5b1332efcf5ed6fb7ae62cdc3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 8 Aug 2021 12:20:28 -0600 Subject: [PATCH] power: Add a POWER config At present we have SPL_POWER but not piain POWER. This works because there is a special build rule in Makefile that always includes the drivers/power directory. It is better to have all driver directories included by drivers/Makefile and there is already a rule in there for this purpose. It just needs a Kconfig for U-Boot proper, so add one. Update the pmic.h header file so that it defines the old pmic struct always, when driver model is not in use. That will avoid build errors for boards which enable POWER but not DM_PMIC. Enable this option always. That seems strange at first sight, but it actually but mimics the current Makefile behaviour. Once we can drop the old PMICs it should be easy enough to rename DM_PMIC to POWWER, or something similar.
