Subject: [PATCH v4 05/15] lib: utils/reset: Use kconfig for enabling/disabling drivers
Date: Sun, 31 Jul 2022 10:26:43 +0530 [thread overview]
Message-ID: <20220731045653.165058-6-apatel@ventanamicro.com> (raw)
In-Reply-To: <20220731045653.165058-1-apatel@ventanamicro.com>
We update reset drivers makefile to use kconfig for enabling/disabling
drivers. To avoid compile errors, we also enable appropriate reset
drivers for each platform.
