Hello,
This is version 7 of the patch series that combines the dwc2 gadget and host
driver into a single dual role driver. Here are the main differences from V6:
- patch 1/8: Addressed Felipe's comment on which variables should not be just
limited to gadget(phy, uphy, regulator_bulk_data_supplies, irq, clk,
debug_root, debug_file, and debug_fifo).
- patch 2/8: Move conversion to use dev_pm_ops API to separate patch.
- patch 3/8: Convert to use dev_pm_ops API
- patch 4/8: Rebased to s3c_hsotg_core_init is now
s3c_hsotg_core_init_disconnected(), followed by s3c_hsotg_core_connect().
- patch 5/8: Use IRQF_SHARED to have s3c_hsotg_irq handle gadget interrupts.
Had to remove paulz's Acked-by for this patch, as it is not quite the same
patch when his ack was given.
- patch 6/8: Assign clk=NULL if a clock is not provided.
- patch 7/8: Moved ahead of Kconfig/Makefile patch to avoid a build error when
patch 8 is applied to dual-role.
- patch 8/8: none
For v7, the series is rebased on top of Felipe Balbi's tree on -next
branch. I thought this might be appropriate as there are dwc2 patches already
on this branch.
As usual, tested on SOCFPGA(host, gadget, and dual-role) and on Rpi-B
(host mode only).
I have pushed this series to a git repo to make it more convenient for people
to test/review.
