Hello, This series adds support for the Cadence PCIe controller on TI's K3 family of SoCs to which the J7200 SoC belongs. The driver is an adaptation of the Linux driver (drivers/pci/controller/cadence/pci-j721e.c) and has been implemented specifically for Root-Complex mode of operation on the J7200 SoC. A minor set of changes will be sufficient to support other K3 SoCs as well with plans to implement it in the near future.
Series is based on commit a404065479 power: pmic: pca9450: Add missing newline of the master branch of U-Boot. v1 of this series was posted as an RFC at: https://patchwork.ozlabs.org/project/uboot/cover/20240821145908.3408573-1-s-vadapa...@ti.com/ Changes since v1: - Addressed Tom's feedback at: https://patchwork.ozlabs.org/project/uboot/patch/20240821145908.3408573-2-s-vadapa...@ti.com/#3365925 by removing extra headers and replacing usleep_range() with udelay(). - Added inbound translation configuration thereby enabling support for NVMe devices. - Added SoC specific quirks and the corresponding code to handle them. - Updated j7200_evm_a72_defconfig to enable NVMe configs since NVMe is now supported with this series. The logs corresponding to validating PCI Root-Complex functionality with an NVMe SSD connected to the PCIe Connector on J7200-EVM are at: https://gist.github.com/Siddharth-Vadapalli-at-TI/18a64e0c258f74274d80c5871594f0dc Regards, Siddharth.
