Subject: [PATCH 2/2] PCI: dwc: Remove unused PCIE_ATU_UNR_* register definitions
Date: Sat, 12 Sep 2026 00:25:37 +0800 [thread overview]
Message-ID: <20260911162537.469018-3-18255117159@163.com> (raw)
In-Reply-To: <20260911162537.469018-1-18255117159@163.com>
The PCIE_ATU_UNR_* macros are not used anywhere in the kernel. They
were presumably intended for unrolled iATU register access, but the
driver now uses the ATU_* macros and computes unrolled offsets via
ATU_UNROLL_BASE().
Remove these unused definitions. No functional change intended.
