git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for 4.14 Detailed description for this pull request: 1. Add new 'extcon-usbc-cros-ec.c' driver - ChromeOS Embedded Controller extcon driver supports the detection of the Display Port (EXTCON_DISP_DP) through USB C-type and contol it. 2. Update extcon core - Modify the description for both functions and structures in order to improve the readability and give the more correct guide about the role of functions because there are different explanation even if the same arguments. - Keep the indentation with tab instead of space - Remove the following deprecated extcon API. The deprecated API are exchanged on all of linux tree. : extcon_get_cable_state_() -> extcon_get_state() : extcon_set_cable_state_() -> extcon_set_state_sync() 3. Include the two immutable branch as following: - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory. - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API because the usb/phy driver usese the deprecated extcon API. So, this immutable branch alters the extcon API and then remove them from extcon. 4. Fix minor issue of extcon driver - Fix the MHL detection on extcon-max77693.c - Convert to using %pOF instead of full_name on extcon.c - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

This pull request is, however, all over the place. Most of the changes are in the bdc driver adding support for USB Phy layer and PM. Renesas adds support for R-Car H3 ES2.0 and R-Car M3-W SoCs. Also here is PM_RUNTIME support for dwc3-keystone. UDC Core got a DMA unmap fix to make sure we only unmap requests that were, indeed, mapped. Other than these, we have a lot of cleanups, many of them adding 'const' to several places.

That quirk is required to make USB Ethernet gadget working on HW that can't cope with unaligned DMA. For some reason only f_ncm sets up that quirk, let's setup it directly in u_ether so other network models would have that quirk applied as well. All network models have been tested with ChipIdea UDC driver on NVIDIA Tegra20 SoC that require DMA to be aligned.

2017-08-18usb: gadget: serial: fix oops when data rx'd after closeStephen Warren1-1/+1
When the gadget serial device has no associated TTY, do not pass any received data into the TTY layer for processing; simply drop it instead. This prevents the TTY layer from calling back into the gadget serial driver, which will then crash in e.g. gs_write_room() due to lack of gadget serial device to TTY association (i.e. a NULL pointer dereference).

2017-08-18USB: Gadget core: fix inconsistency in the interface ↵Alan Stern1-6/+9
tousb_add_gadget_udc_release() The usb_add_gadget_udc_release() routine in the USB gadget core will sometimes but not always call the gadget's release function when an error occurs. More specifically, if the struct usb_udc allocation fails then the release function is not called, and for other errors it is. As a result, users of this routine cannot know whether they need to deallocate the memory containing the gadget structure following an error. This leads to unavoidable memory leaks or double frees. This patch fixes the problem by splitting the existing device_register() call into device_initialize() and device_add(), and doing the udc allocation in between. That way, even if the allocation fails it is still possible to call device_del(), and so the release function will be always called following an error.

2017-08-15usb: bdc: fix "xsf for ep not enabled" errrorAl Cooper1-3/+4
This patch essentially clears the port status change bits at the correct times. It is necessary because the driver was not handling the change bits correctly for events during device connection/disconnection and bus enumeration. So, one of them (PCC) was left stuck sometimes causing the "xsf for ep not enabled" error we get on first connection. This was found by the Android team. This was debugged and fixed by Sasi Kumar.

This adds 3 new options to the RNDIS gadget function configs. It allows overriding the default USB interface class/subclass/protocol. The motivation for this is that if you set the values to "ef" (Misc), "04" (RNDIS), "01" (Ethernet) respectively, then the device will be recognized by the rndiscmp.inf file in Windows Vista and newer and will cause Windows to load the correct RNDIS driver without the need for a custom (signed) .inf file.

2017-08-15usb: gadget: core: unmap request from DMA only if previously mappedJack Pham1-1/+4
In the SG case this is already handled since a non-zero request->num_mapped_sgs is a clear indicator that dma_map_sg() had been called. While it would be nice to do the same for the singly mapped case by simply checking for non-zero request->dma, it's conceivable that 0 is a valid dma_addr_t handle. Hence add a flag 'dma_mapped' to struct usb_request and use this to determine the need to call dma_unmap_single(). Otherwise, if a request is not DMA mapped then the result of calling usb_request_unmap_request() would safely be a no-op.

2017-08-15usb: gadget: f_midi: Use snd_card_free_when_closed with refcountJerry Zhang1-5/+17
Currenly, f_midi_free uses snd_card_free, which will wait until the user has released the sound card before returning. However, if the user doesn't release the sound card, then f_midi_free can block for an arbitrary amount of time, which also blocks any gadget operations on that thread. Instead, we can use snd_card_free_when_closed which returns before all handles are released. Since f_midi can be accessed through rmidi if usb_put_function is called before release_card_device, add refcounting to f_midi_free and have rawmidi's private free call it. The f_midi memory is only kfreed when usb_put_function and release_card_device have both been called.

As USB_SNP_CORE is selected by USB_SNP_UDC_PLAT and USB_AMD5536UDC, these should depend on HAS_DMA, too. For USB_AMD5536UDC, this is already fulfilled through the dependency on USB_PCI (PCI implies HAS_DMA). Add dependencies on HAS_DMA to fix this.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "This development cycle resulted in a fair amount of changes in both core and driver sides. The most significant change in ALSA core is about PCM. Also the support of of-graph card and the new DAPM widget for DSP are noteworthy changes in ASoC core. And there're lots of small changes splat over the tree, as you can see in diffstat. Below are a few highlights: ALSA core: - Removal of set_fs() hackery from PCM core stuff, and the code reorganization / optimization thereafter - Improved support of PCM ack ops, and a new ABI for improved control/status mmap handling - Lots of constifications in various codes ASoC core: - The support of of-graph card, which may work as a better generic device for a replacement of simple-card - New widget types intended mainly for use with DSPs ASoC drivers: - New drivers for Allwinner V3s SoCs - Ensonic ES8316 codec support - More Intel SKL and KBL works - More device support for Intel SST Atom (mostly for cheap tablets and 2-in-1 devices) - Support for Rockchip PDM controllers - Support for STM32 I2S and S/PDIF controllers - Support for ZTE AUD96P22 codecs HD-audio: - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks for HP and Dell machines - A few more fixes for i915 component binding" * tag 'sound-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (418 commits) ALSA: hda - Fix unbalance of i915 module refcount ASoC: Intel: Skylake: Remove driver debugfs exit ASoC: Intel: Skylake: explicitly add the headers sst-dsp.h ALSA: hda/realtek - Remove GPIO_MASK ALSA: hda/realtek - Fix typo of pincfg for Dell quirk ALSA: pcm: add a documentation for tracepoints ALSA: atmel: ac97c: fix error return code in atmel_ac97c_probe() ALSA: x86: fix error return code in hdmi_lpe_audio_probe() ASoC: Intel: Skylake: Add support to read firmware registers ASoC: Intel: Skylake: Add sram address to sst_addr structure ASoC: Intel: Skylake: Debugfs facility to dump module config ASoC: Intel: Skylake: Add debugfs support ASoC: fix semicolon.cocci warnings ASoC: rt5645: Add quirk override by module option ASoC: rsnd: make arrays path and cmd_case static const ASoC: audio-graph-card: add widgets and routing for external amplifier support ASoC: audio-graph-card: update bindings for amplifier support ASoC: rt5665: calibration should be done before jack detection ASoC: rsnd: constify dev_pm_ops structures.
