[PATCH 11/11] arm64: dts: renesas: r8a779f0: Describe the PCIe AER interrupts
From: Koichiro Den
Date: Thu Sep 17 2026 - 23:25:04 EST
The PCIe controllers report Root Port AER notifications through
intreq_pci0_lperr (SPI 421) and intreq_pci1_lperr (SPI 428),
respectively, separately from the integrated MSI receiver interrupts.
Describe these interrupts with the "aer" name so the controller driver
can use them for Root Port error reporting.
Append the new interrupts to preserve the existing interrupt indices.
