It always requires external 1V1 power and can optionally use external 3V3 power (or alternatively it has a 5V->3V3 LDO built in to derive 3V3 power from VBUS). It also exposes a reset pin. Device tree bindings are merged for upstream release with Linux 7.1 as commit bfcb86e58f3a ("dt-bindings: usb: Add Corechips SL6341 USB2.0/3.0 hub controller") [1] Link: https://github.com/torvalds/linux/commit/bfcb86e58f3a58d05b95970d81b94cb011982780 [1] Signed-off-by: Alexey Charkov Reviewed-by: Marek Vasut Reviewed-by: Quentin Schulz --- diff --git a/common/usb_onboard_hub.c b/common/usb_onboard_hub.c index 6fc34489a98..0684f7bfd47 100644 --- a/common/usb_onboard_hub.c +++ b/common/usb_onboard_hub.c @@ -262,6 +262,12 @@ static int usb_onboard_hub_remove(struct udevice *dev) return ret; } +static const struct onboard_hub_data corechips_sl6341_data = { + .reset_us = 10000, + .num_supplies = 2, + .supply_names = { "vdd1v1-supply", "vdd3v3-supply" }, +}; + static const struct onboard_hub_data usb2514_data = { .power_on_delay_us = 500, .reset_us = 1, @@ -285,7 +291,13 @@ static const struct onboard_hub_data usbhx3_data = { static const struct udevice_id usb_onboard_hub_ids[] = { /* Use generic usbVID,PID dt-bindings (usb-device.yaml) */ - { .compatible = "usb424,2514", /* USB2514B USB 2.0 */ + { .compatible = "usb3431,6241", /* Corechips SL6341 USB 2.0 */ + .data = (ulong)&corechips_sl6341_data, + }, { + .compatible = "usb3431,6341", /* Corechips SL6341 USB 3.0 */ + .data = (ulong)&corechips_sl6341_data, + }, { + .compatible = "usb424,2514", /* USB2514B USB 2.0 */ .data = (ulong)&usb2514_data, }, { .compatible = "usb424,2744", /* USB2744 USB 2.0 */
