The main changes are adding several system interfaces for tuning performance, and each vendors can adjust them according to their design configurations. Others are tiny improvements, like more well siTD supports, USB_DEVICE_A_HNP_SUPPORT supports, etc. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJVzU3lAAoJEEhZKYFQ1nG7nZ4H/AsCAhoiUqcyP4fRziaZzexa F55CuhIVd6vg6vhuiccoUo4XZXR6IsZikczNowWphqXhtQUBr/rvv0VSb2sMxZfn AgdNuinhGUat4rdcf0earr9+EQzjbdrHoxDzFKes21S0vS+J3TaYUk6F7Q6sUL81 t97itMmKBrffMZLsQzB9MJo4E8mD4JNlWu/ezGNu11ZD2/w8Ha7GpyExyb2AGHrs M1rlE6Ph8AKpyECI7OecCxPIDyDRuUQ8Bvj+MkR9BrDX1gOv512ZLfRbIGJCqVOO A2Urzh/jEI9e7ttGqSpMxGYKZ4wvZ7Ta5IvLLseb0vszM2oQGDNHcJx7fKOuUVU= =IIud -----END PGP SIGNATURE----- Merge tag 'usb-ci-v4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/peter.chen/usb into usb-next Peter writes: USB: chipidea updates for v4.3-rc1 The main changes are adding several system interfaces for tuning performance, and each vendors can adjust them according to their design configurations.
