However, it has been confirmed that this is not the case and the mux'ing options much more limited. Unfortunately, the public documentation has not been updated to reflect this and so detail the actual mux'ing options here by function: Function: Lanes: pcie1 x2: pcie3, pcie4 pcie1 x4: pcie1, pcie2, pcie3, pcie4 pcie2 x1 (option1): pcie0 pcie2 x1 (option2): pcie2 usb3 port 0: pcie0 usb3 port 1 (option 1): pcie1 usb3 port 1 (option 2): sata0 sata: sata0 Signed-off-by: Jon Hunter --- drivers/pinctrl/pinctrl-tegra-xusb.c | 9 --------- 1 file changed, 9 deletions(-) diff --git a/drivers/pinctrl/pinctrl-tegra-xusb.c b/drivers/pinctrl/pinctrl-tegra-xusb.c index 2651d04bd1be..84a43e612952 100644 --- a/drivers/pinctrl/pinctrl-tegra-xusb.c +++ b/drivers/pinctrl/pinctrl-tegra-xusb.c @@ -760,24 +760,15 @@ static const char * const tegra124_pcie_groups[] = { "pcie-2", "pcie-3", "pcie-4", - "sata-0", }; static const char * const tegra124_usb3_groups[] = { "pcie-0", "pcie-1", - "pcie-2", - "pcie-3", - "pcie-4", "sata-0", }; static const char * const tegra124_sata_groups[] = { - "pcie-0", - "pcie-1", - "pcie-2", - "pcie-3", - "pcie-4", "sata-0", }; -- 2.1.4
