usb: dwc2: Modify dwc2_readl/writel functions prototype

2018-07-30T07:39:16+00:00

Added hsotg argument to dwc2_readl/writel function prototype,
and also instead of address pass offset of register.
hsotg will contain flag field for endianness.

Also customized dwc2_set_bit and dwc2_clear_bit function for
dwc2_readl/writel functions.

USB: dwc2: no need to check return value of debugfs_create functions

2018-05-31T10:54:22+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

usb: dwc2: debugfs: Don't touch RX FIFO during register dump

2018-05-15T07:17:00+00:00

Dumping the registers via debugfs makes USB on Raspberry Pi completely
unusable. The read of register GRXSTSP ("Receive Status Read and Pop
Register") is responsible for this behaviour, because it pops the RX FIFO.
So avoid this by omitting the relevant register.

usb: dwc2: Add Interpacket Gap(IPG) feature support

2018-05-15T07:16:47+00:00

Added GHWCFG4_IPG_ISOC_SUPPORTED and DCFG_IPG_ISOC_SUPPORDED
bits definitions to enable/disable IPG feature.

Added ipg_isoc_en core parameter which will indicate IPG support
enable/disable and initialize it.

usb: dwc2: Rename hibernation to partial_power_down

2018-03-13T08:47:53+00:00

No-op change, only rename.

This code was misnamed originally. It was only responsible for partial
power down and not for hibernation.

Rename core_params->hibernation to core_params->power_down,
dwc2_set_param_hibernation() to dwc2_set_param_power_down().

Add lpm, lpm_clock_gating, besl, hird_threshold_en and hird_threshold
core parameters. These will indicate LPM and LPM Errata support
as well as chosen L1 sleeping mode for the core and PHY.

USB: dwc2: Remove redundant license text

2017-11-07T14:45:01+00:00

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner.  So the extra GPL text wording
can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.
