The VIM3 schematic can be found at [1]. This patchset is dependent on Remi's "Fix reset assertion via gpio descriptor" patch at [2]. This patchset has been tested in a A311D VIM3 and S905D3 VIM3L using a 128Go TS128GMTE110S NVMe PCIe module. For indication, here is a bonnie++ run as ext4 formatted on the VIM3: ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP 4G 93865 99 312837 96 194487 23 102808 97 415501 21 +++++ +++ and the S905D3 VIM3L version: ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP 4G 52144 95 71766 21 47302 10 57078 98 415469 44 +++++ +++ Changes since v1 at [3]: - Collected Andrew's and Rob's Reviewed-by tags - Added missing calls to phy_init/phy_exit - Fixes has_shared_phy handling for MIPI clock - Add comment in the DT concerning firmware setting the right properties - Added SM1 Power Domain to PCIe node [1] https://docs.khadas.com/vim3/HardwareDocs.html [2] https://patchwork.kernel.org/patch/11125261/ [3] https://patchwork.kernel.org/cover/11136927/ Neil Armstrong (6): dt-bindings: pci: amlogic,meson-pcie: Add G12A bindings PCI: amlogic: Fix probed clock names PCI: amlogic: meson: Add support for G12A phy: meson-g12a-usb3-pcie: Add support for PCIe mode arm64: dts: meson-g12a: Add PCIe node arm64: dts: khadas-vim3: add commented support for PCIe .../bindings/pci/amlogic,meson-pcie.txt | 12 +- .../boot/dts/amlogic/meson-g12-common.dtsi | 33 +++++ .../amlogic/meson-g12b-a311d-khadas-vim3.dts | 25 ++++ .../amlogic/meson-g12b-s922x-khadas-vim3.dts | 25 ++++ .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 4 + .../dts/amlogic/meson-sm1-khadas-vim3l.dts | 25 ++++ arch/arm64/boot/dts/amlogic/meson-sm1.dtsi | 4 + drivers/pci/controller/dwc/pci-meson.c | 132 ++++++++++++++---- .../phy/amlogic/phy-meson-g12a-usb3-pcie.c | 70 ++++++++-- 9 files changed, 292 insertions(+), 38 deletions(-)
