Subject: [PATCH 1/4] mod_devicetable: helper macro for declaring oftree module device table
Date: Sat, 1 Jun 2019 15:52:56 +0200 [thread overview]
Message-ID: <1559397179-5833-2-git-send-email-info@metux.net> (raw)
In-Reply-To: <1559397179-5833-1-git-send-email-info@metux.net>
Little helper macros that declares an oftree module device table,
if CONFIG_OF is enabled. Otherwise it's just noop. Helpful for
reducing the number of #ifdef's.
Instead of:
MODULE_DEVICE_TABLE(of, foo);
now use:
MODULE_OF_TABLE(foo);
Or declare the whole table via:
MODULE_DECLARE_OF_TABLE(foo,
{ .compatible = "foo" },
{ .compatible = "bar" });
