usb: dwc2: Remove dwc2_set_all_params function

2016-11-18T11:54:11+00:00

Replace this by statically defining a function with defaults, and just
assigning it. This will allow us to use parameters of any type and any
default value.

usb: dwc2: Declare the core params struct statically

2016-11-18T11:54:11+00:00

This makes it consistent with the hw_params struct and simplifies the
memory management for future refactoring. Fix up usage in all files.

usb: dwc2: Add params.c file

2016-11-18T11:54:10+00:00

all the static parameter definitions.

Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2016-10-08T04:34:49+00:00

Pull ARM SoC late DT updates from Arnd Bergmann:
 "These updates have been kept in a separate branch mostly because they
  rely on updates to the respective clk drivers to keep the shared
  header files in sync.

   - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
     automotive SoC similar to the ⅹ8a7795 chip we already support, but
     the dts changes rely on a clock driver change that has been merged
     for v4.9 through the clk tree.

   - The Amlogic meson-gxbb (S905) platform gains support for a few
     drivers merged through our tree, in particular the network and usb
     driver changes are required and included here, and also the clk
     tree changes.

   - The Allwinner platforms have seen a large-scale change to their clk
     drivers and the dts file updates must come after that. This
     includes the newly added Nextthing GR8 platform, which is derived
     from sun5i/A13.

   - Some integrator (arm32) changes rely on clk driver changes.

   - A single patch for lpc32xx has no such dependency but wasn't added
     until just before the merge window"

usb: dwc2: host: Set host_rx_fifo_size to 525 for rk3066

2016-03-04T13:14:39+00:00

As documented in dwc2_calculate_dynamic_fifo(), host_rx_fifo_size should
really be:
 2 * ((Largest Packet size / 4) + 1 + 1) + n
 with n = number of host channel.

We have 9 host channels, so
 2 * ((1024/4) + 2) + 9 = 516 + 9 = 525

We've got 960 / 972 total_fifo_size on rk3288 (and presumably on
rk3066) and 525 + 128 + 256 = 909 so we're still under on both ports
even when we increment by 5.

In the future, it would be nice if dwc2_calculate_dynamic_fifo() could
handle the "too small" FIFO case and come up with something more
dynamically.  When we do that we can figure out how to allocate the
extra 48 / 60 bytes of FIFO that we're currently wasting.

NOTE: no known bugs are fixed by this patch, but it seems like a simple
fix and ought to fix someone.
