Subject: [PATCH v7 03/37] sh: Enable OF support for build and configuration.
Date: Thu,  4 Apr 2024 13:59:28 +0900
Message-Id: <e7e72f19f8155cbda4741c04448eb1f7624df161.1712205900.git.ysato@users.sourceforge.jp>
In-Reply-To: <cover.1712205900.git.ysato@users.sourceforge.jp>
References: <cover.1712205900.git.ysato@users.sourceforge.jp>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

IRQ, CLK and PCI will be migrated to a common driver framework.
So if OF, disable the SH specific drivers.
