This patchset enables hard wired hub device to use different bInterval from its descriptor when the hub has a combined device node. When we know reducing autosuspend delay for built-in HIDs is better for power saving, we can reduce it to the optimal value. But if a parent hub has a long bInterval, mouse lags a lot from more frequent autosuspend. So this enables overriding bInterval for a hard wired hub device only when we know that reduces the power consumption. Changes in v4 - use of_property_read_u32() instead of of_property_read_u8() Ikjoon Jang (2): dt-bindings: usb: add "hub,interval" property usb: overridable hub bInterval by device node Documentation/devicetree/bindings/usb/usb-device.txt | 4 ++++ drivers/usb/core/config.c | 9 +++++++++ 2 files changed, 13 insertions(+) -- 2.24.0.393.g34dc348eaf-goog
