Link: https://lore.kernel.org/linux-riscv/20230111125323.1911373-1-daire.mcnamara@microchip.com/ Resending with correct e-mail address list These patches are regenerated on v6.5-rc3. Main changes from v2: - Reworked "Gather MSI information..." as suggested by Bjorn - merged 'Gather MSI Information..." and "Rename and refactor" as suggested by Bjorn - Re-generated on v6.5-rc3 Main Changes from v1: - Dropped "Remove cast warning for devm_add_action_or_reset()". This has been overtaken by a patch series from Krzysztof Wilczynski. - Improved the comment for "Enable building driver as a module" to clarify what enables building the driver as a module. - Split "Gather MSI information from hardware config registers", for clarity, into: - "Gather MSI information from hardware config registers" purely changing the of source of MSI-related information (Num MSIs and MSI address) from #defines (which can be incorrect) to FPGA configuration registers (which is the ultimate source of truth), and a - "Rename and refactor ..." patch as a function's code is now clearly unrelated to its current name. cc: Conor Dooley cc: Lorenzo Pieralisi cc: "Krzysztof Wilczyński" cc: Rob Herring cc: Bjorn Helgaas cc: linux-riscv@lists.infradead.org cc: linux-pci@vger.kernel.org Daire McNamara (8): PCI: microchip: Correct the DED and SEC interrupt bit offsets PCI: microchip: Enable building driver as a module PCI: microchip: Align register, offset, and mask names with hw docs PCI: microchip: Enable event handlers to access bridge and ctrl ptrs PCI: microchip: Clean up initialisation of interrupts PCI: microchip: Gather MSI information from hardware config registers PCI: microchip: Re-partition code between probe() and init() drivers/pci/controller/Kconfig | 2 +- drivers/pci/controller/pcie-microchip-host.c | 393 +++++++++++-------- 2 files changed, 233 insertions(+), 162 deletions(-) base-commit: 6eaae198076080886b9e7d57f4ae06fa782f90ef
