Subject: [PATCH v2 08/18] PCI: rockchip-ep: Use a macro to define EP controller .align feature
Date: Sat, 30 Mar 2024 13:19:18 +0900 [thread overview]
Message-ID: <20240330041928.1555578-9-dlemoal@kernel.org> (raw)
In-Reply-To: <20240330041928.1555578-1-dlemoal@kernel.org>
Introduce the macro ROCKCHIP_PCIE_AT_SIZE_ALIGN defined using
ROCKCHIP_PCIE_AT_MIN_NUM_BITS to initialize the .align field of the
controller epc_features structure, avoiding using the "magic" value 8
directly.
