Hi all, In this series, I add several new interfaces for chipidea driver, they are mainly for system configuration adjustment. The USB performance may be improved with these configuration changing, but each vendor driver owner needs to consult with your IC owner which configuration parameters are suitable for your system before changing it, and only change it if necessary. The other changes are for imx, it shows how imx uses these interfaces. Shawn, the patch [5/10] and [9/10] are dts changes, help to review it please. Changes for v3: - Improve the binding doc according to Rob's comment [Patch 4/10, 8/10] Changes for v2: - Use the bit fields which are not used. [Patch 2/10, 6/10, 10/10] - According to Greg and Sascha comments, format patch 2/10's commit log. - using non-burst instead of unburst for patch 7/10 Peter Chen (10): usb: chipidea: udc: zero-length packet is only needed for TX usb: chipidea: define stream mode disable for both roles usb: chipidea: imx: add stream mode enable for device mode at imx6sl/imx6sx Doc: usb: ci-hdrc-usb2: add ahb-burst-config for binding doc ARM: imx6: set ahb-burst-config as 0 for USB usb: chipidea: add ahb burst configuration interface usb: chipidea: usbmisc_imx: add non-burst setting for imx6 Doc: usb: ci-hdrc-usb2: add tx(rx)-burst-config-dword for binding doc ARM: imx6: change default burst size for USB usb: chipidea: add tx/rx burst size configuration interface .../devicetree/bindings/usb/ci-hdrc-usb2.txt | 17 ++++++ arch/arm/boot/dts/imx6qdl.dtsi | 12 +++++ arch/arm/boot/dts/imx6sl.dtsi | 9 ++++ arch/arm/boot/dts/imx6sx.dtsi | 9 ++++ drivers/usb/chipidea/bits.h | 7 +++ drivers/usb/chipidea/ci.h | 1 + drivers/usb/chipidea/ci_hdrc_imx.c | 16 +++--- drivers/usb/chipidea/core.c | 62 +++++++++++++++++++++- drivers/usb/chipidea/udc.c | 2 +- drivers/usb/chipidea/usbmisc_imx.c | 12 ++++- include/linux/usb/chipidea.h | 11 +++- 11 files changed, 147 insertions(+), 11 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
