Hello,
This patch series combines the dwc2 host driver and the s3c-hsotg peripheral
driver into a single dual-roler driver similar to the dwc3.
The patch series moves the s3c-hsotg files into the /dwc2 folder, so this is
the final location of the driver. When the driver is built as a kernel module,
it will be dwc2.ko and dwc2_platform.ko.
patch 1/7 : Edit the defines in dwc2/hw.h so that the s3c-hsotg driver can use
the defines in hw.h. So we can remove s3c-hsotg.h in a subsequent
patch.
patch 2/7 : Moves the s3c-hsotg driver into /dwc2 folder. Building the s3c-hsotg
driver will now be a Kconfig option under DWC2. Also replaces the
s3c-hsotg.h header file for dwc2/hw.h.
patch 3/7 : Moves the s3c-hsotg data structure into a common place, core.h, so
that final DRD can use it.
patch 4/7 : Add the gadget data structure to a common data structure,
dwc2_hsotg, which is the data structure that will encapsulate host
and peripheral modes for the final DRD. The bulk for this patch
is edits the in s3c-hsotg.c to reference the new data structure.
patch 5/7 : Replaces the s3c_hostg_irq handler with the dwc2_handle_common_intr
in dwc2. Updates the dwc2 IRQ routines to call the s3c-hsotg gadget
functions for peripheral mode.
patch 6/7 : Update the Kconfig and Makefile to enable building of the single
DRD. At this stage the the driver is behaving as a dual-role driver.
patch 7/7 : Decouple host/peripheral functionality when buildling the driver in
host or peripheral mode only.
This patchset is based on 3.14-rc2. I have only tested on the SOCFPGA platform
which has v2.93a of dual-role IP.
Thanks,
