Hello,
This is version 3 of the patch series that combines the dwc2 gadget and host
driver into a single dual role driver. Here are the main differences from V2:
- less code change:
v3: 9 files changed, 340 insertions(+), 335 deletions(-)
v2: 9 files changed, 368 insertions(+), 357 deletions(-)
v1: 9 files changed, 877 insertions(+), 904 deletions(-)
- Patch 1/12 : Add a USB_GADGET=USB_DWC2 dependency for peripheral and
dual-role builds
- Patch 3/12 : Per paulz's code suggestion to avoid a double pointer usage in
order to keep the gadget driver cleaner, the gadget variable declarations
are only visible for peripheral and dual-role builds of the driver.
Also, in a effort to maintain bisectability, move v2's [usb: dwc2: Moves
s3c_hsotg gadget data structure into dwc2_hsotg] and [usb: dwc2: update
gadget portion to use common dwc2_hsotg structure] into a single patch for
v3. In V3, a single patch [usb: dwc2: Moves s3c_hsotg gadget data structure
into dwc2_hsotg] is the result. For this series, there are 12 patches
instead of 13.
For v3, I have rebased the series on top of the following patches:
Doug Anderson: usb: dwc2: Read GNPTXFSIZ when in forced HOST mode
Kever Yang : usb: dwc2: add 'mode' which based on Kconfig select or dts setting
Robert Baldyga : usb: dwc2/gadget: fix series <- 12 patches
As usual, tested on SOCFPGA(host, gadget, and dual-role) and on Rpi-B(host mode).
This patch series is based on v3.16. I have pushed this a git repo to make
it more convenient for people to test/review.
