Subject: [PATCH v8 14/15] arm64: dts: cix: Add PCIe Root Complex on sky1
Date: Tue, 19 Aug 2025 19:52:38 +0800 [thread overview]
Message-ID: <20250819115239.4170604-15-hans.zhang@cixtech.com> (raw)
In-Reply-To: <20250819115239.4170604-1-hans.zhang@cixtech.com>
From: Hans Zhang <hans.zhang@cixtech.com>
Add pcie_x*_rc node to support Sky1 PCIe driver based on the
Cadence PCIe core.
Supports Gen1/Gen2/Gen3/Gen4, 1/2/4/8 lane, MSI/MSI-x interrupts
using the ARM GICv3.
Signed-off-by: Hans Zhang <hans.zhang@cixtech.com>

Changes for v8:
- The rcsu register is split into two parts: rcsu_strap and rcsu_status.
