Chipidea changes for v4.14-rc1
- Add chipidea support at Nvidia SoCs
- Improvement for extcon support
- Some code refines
|
|
All of these Tegra SoC generations have a ChipIdea UDC IP block that can
be used for device mode communication with a host. Implement rudimentary
support that doesn't allow switching between host and device modes.

NVIDIA Tegra20 UDC can't cope with unaligned DMA and require a USB gadget
quirk that avoids SKB buffer alignment to be set in order to make Ethernet
Gadget working. Later Tegra generations do not require that quirk. Let's
add a new platform data flag that allows to enable USB gadget quirk for
platforms that require it.

When the RESET bit is set in the USBCMD register it resets quite
a few of the wrapper's registers to their reset state. This
includes the GENCONFIG and GENCONFIG2 registers. Currently this
is done by the usb phy and ehci-msm drivers writing into the
controller wrapper's MMIO address space. Let's consolidate the
register writes into the wrapper driver instead so that we
clearly split the wrapper from the phys.

We need to pick the correct phy at runtime based on how the SoC
has been wired onto the board. If the secondary phy is used, take
it out of reset and mux over to it by writing into the TCSR
register. Make sure to do this on reset too, because this
register is reset to the default value (primary phy) after the
RESET bit is set in USBCMD.

The msm chipidea controller uses two main clks, an AHB clk to
read/write the MMIO registers and a core clk called the system
clk that drives the controller itself. Add support for these clks
as they're required in all designs.
Also add support for an optional third clk that we need to turn
on to reset the controller and wrapper logic and other
"housekeeping" things. This clk was removed in later revisions of
the hardware because the reset methodology no longer required
clks to be enabled to propagate resets.

The core framework already handles setting this parameter with a
platform quirk. Add the appropriate flag so that we always set
AHBBURST to 0. Technically DT should be doing this, but we always
do it for msm chipidea devices so setting the flag in the driver
works just as well. If the burst needs to be anything besides 0,
we expect the 'ahb-burst-config' dts property to be present.

We're not properly marking the glue layer/wrapper device as
runtime active, so runtime PM believes that the hardware state is
inactive when we call pm_runtime_enable() in this driver. This
causes a problem when the glue layer has a power domain
associated with it, because runtime PM will go and disable the
power domain to match the 'inactive' state of the device. Let's
mark the device as active so that runtime PM doesn't improperly
power down this device when it's actually active.

The chipidea/udc.c file sends a CI_HDRC_CONTROLLER_RESET_EVENT to
the wrapper drivers when it calls hw_device_reset(), but that
function is not called from chipidea/host.c. And the udc.c file
sends the CI_HDRC_CONTROLLER_STOPPED_EVENT but the host.c file
doesn't do anything.
The intent of the reset event is to allow the wrapper driver to
do any wrapper specific things after the reset bit has been set
in the usb command register. Therefore, add this event hook in
the host role after we toggle that bit.
Similarly, the intent of the stopped event is to allow the
wrapper driver to do any wrapper specific things after the device
is stopped. So when we stop the host role, send the stopped
event.

We're currently emulating the vbus and id interrupts in the OTGSC
read API, but we also need to make sure that if we're handling
the events with extcon that we don't enable the interrupts for
those events in the hardware. Therefore, properly emulate this
register if we're using extcon, but don't enable the interrupts.
This allows me to get my cable connect/disconnect working
properly without getting spurious interrupts on my device that
uses an extcon for these two events.

With the id and vbus detection done via extcon we need to make

simplify it for polling the OTGSC register. Then we can make
certain we only use the hw_read_otgsc() API to read OTGSC, which
will make sure we properly handle extcon events.

ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.
Get rid of the union and just keep ktime_t as simple typedef of type s64.
The conversion was done with coccinelle and some manual mopping up.

We want the USB fixes in here as well.
