Subject: [PATCH V2 1/3] reset: imx7: Support module build
Date: Mon, 29 Jun 2020 23:05:27 +0800 [thread overview]
Message-ID: <1593443129-18766-1-git-send-email-Anson.Huang@nxp.com> (raw)
Add module device table, author, description and license to support
module build, and CONFIG_RESET_IMX7 is changed to default 'y' ONLY
for i.MX7D, other platforms need to select it in defconfig.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
---
Changes since V1:
- make it default 'y' for SOC_IMX7D;
- add module author, description;
- use device_initcall instead of builtin_platform_driver() to support
module unload.
