Apologies for the rapid fire (I tend to be much more conservative when resending series), but given that this series has a direct impact on other projects (such as u-boot), I'm trying to converge as quickly as possible. This series aims at fixing a number of issues for the recently merged Apple PCIe driver, all revolving around the mishandling of #PERST: - we didn't properly drive #PERST, and we didn't follow the specified timings - the DT had the wrong polarity, which has impacts on the driver itself Hopefully, this should address all the issues reported so far. * From v2: - Fixed DT - Fixed #PERST polarity in the driver - Collected Pali's ack on patch #1 [1] https://lore.kernel.org/r/20211122104156.518063-1-maz@kernel.org (local) Marc Zyngier (3): PCI: apple: Follow the PCIe specifications when resetting the port arm64: dts: apple: t8103: Fix PCIe #PERST polarity PCI: apple: Fix #PERST polarity arch/arm64/boot/dts/apple/t8103.dtsi | 7 ++++--- drivers/pci/controller/pcie-apple.c | 12 +++++++++++- 2 files changed, 15 insertions(+), 4 deletions(-) -- 2.30.2 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
