Date: Tue, 9 Jan 2024 17:23:07 +0900 Message-Id: X-Mailer: git-send-email 2.39.2 In-Reply-To: References: Precedence: bulk X-Mailing-List: linux-fbdev@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Add New OF based PCI Host driver. This driver conflicts some point in legacy PCI driver. To resolve the conflict, I made some changes to the legacy driver.
