Armadillo-840mにおいて、コンポジット出力をさせたいと考えて
おります。
この時、カーネルコンフィグは以下のサイトを参考に設定しました。
https://armadillo.atmark-techno.com/howto/a840-use-cvbs-line

また、ソースコードでは、 a840_lcdc1_init()でリソースの登録を
行っているようですが、関数をコールしている所が見つからないため、
初期化（ a840_init ()）にて、関数をコールするようにしてみました。
このカーネルを書き込んで動作させた所、下記のログのようにエラー
となってしまいました。
Armadillo-840ｍでコンポジットを出力させるのに、このように
a840_lcdc1_init() を初期化でコールするようにしていますが、
このやり方で合っているでしょうか？
エラー内容では、リソースの登録が失敗しているような内容と
思われますが、リソース情報として何か追加で登録する必要が
あるでしょうか？
