Subject: [PATCH v4 19/20] coresight: allow catu drivers to be built as modules
Date: Thu, 23 Jul 2020 12:28:01 +0800 [thread overview]
Message-ID: <20200723042802.22511-20-tingwei@codeaurora.org> (raw)
In-Reply-To: <20200723042802.22511-1-tingwei@codeaurora.org>
Allow to build coresight-catu as modules, for ease of development.
- Kconfig becomes a tristate, to allow =m
- add catu_remove functions, for module unload
- add a MODULE_DEVICE_TABLE for autoloading on boot
Signed-off-by: Tingwei Zhang <tingwei@codeaurora.org>
