Date: Thu, 4 Apr 2024 14:14:18 +0900 Message-Id: <429d40e16e70381d25d77c627ae490a2be28a0b7.1712207606.git.ysato@users.sourceforge.jp> X-Mailer: git-send-email 2.39.2 In-Reply-To: References: MIME-Version: 1.0 X-BeenThere: dri-devel@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Direct Rendering Infrastructure - Development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" Initialize the clock and timer using the COMMON_CLK procedure. sh's earlytimer mechanism doesn't work properly in OF, so timer initialization is delayed. If CONFIG_OF=y, perform the general timer initialization procedure.
