2019-11-25phy: phy-twl4030-usb: fix denied runtime accessAndreas Kemnade
[ Upstream commit 6c7103aa026094a4ee2c2708ec6977a6dfc5331d ] When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS, the counter will be incremented but the resume callback not called, so enumeration and charging will not start properly. To avoid that happen, disable irq on suspend and recheck on resume. Practically this happens when the device is woken up from suspend by plugging in usb.

2018-08-24MLK-16918-5: drm: Implement NWL MIPI-DSI as a real drm_bridgeRobert Chiras
Currently, the Northwest Logic MIPI-DSI controller host specific code resides under drm/bridge, but is not a real drm_bridge. It creates a drm_bridge and adds itself to the drm_encoder that handles this file, but this is wrong, since it does not implement the drm_bridge_funcs. The correct way to implement a drm_bridge is to add the drm_bridge and let other components (another bridge or a drm_encoder) to attach to this bridge. Since we are doing this, a new compatible strings can be used for this driver: "nwl,mipi-dsi". Since this was used by nwl_dsi-imx.c, update that driver to use this bridge correctly. This is needed in order to add support for MIPI-DSI on 8MQ. The IMX_NWL driver will either add a DSI encoder to DRM, or a DSI bridge. The encoder will be used by imx-drm-core driver, while the bridge will be used by MXSFB driver (which creates a simple display pipe). Signed-off-by: Robert Chiras <robert.chiras@nxp.com>

2018-01-23phy: work around 'phys' references to usb-nop-xceiv devicesArnd Bergmann
commit b7563e2796f8b23c98afcfea7363194227fa089d upstream. Stefan Wahren reports a problem with a warning fix that was merged for v4.15: we had lots of device nodes with a 'phys' property pointing to a device node that is not compliant with the binding documented in Documentation/devicetree/bindings/phy/phy-bindings.txt This generally works because USB HCD drivers that support both the generic phy subsystem and the older usb-phy subsystem ignore most errors from phy_get() and related calls and then use the usb-phy driver instead. However, it turns out that making the usb-nop-xceiv device compatible with the generic-phy binding changes the phy_get() return code from -EINVAL to -EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns -EPROBE_DEFER from its probe function rather than ignoring the failure, breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is enabled. The same code is used in the dwc3 driver and the usb_add_hcd() function, so a reasonable assumption would be that many other platforms are affected as well. I have reviewed all the related patches and concluded that "usb-nop-xceiv" is the only USB phy that is affected by the change, and since it is by far the most commonly referenced phy, all the other USB phy drivers appear to be used in ways that are are either safe in DT (they don't use the 'phys' property), or in the driver (they already ignore -EPROBE_DEFER from generic-phy when usb-phy is available). To work around the problem, this adds a special case to _of_phy_get() so we ignore any PHY node that is compatible with "usb-nop-xceiv", as we know that this can never load no matter how much we defer. In the future, we might implement a generic-phy driver for "usb-nop-xceiv" and then remove this workaround. Since we generally want older kernels to also want to work with the fixed devicetree files, it would be good to backport the patch into stable kernels as well (3.13+ are possibly affected), even though they don't contain any of the patches that may have caused regressions.

2016-11-17phy: twl4030-usb: Fix for musb session bit based PMTony Lindgren
Now with musb driver implementing generic session bit based PM, we need to have the USB PHYs behaving in a sane way for platforms implementing PM. Currently twl4030-usb enables PM in twl4030_phy_power_on() and then disables it in twl4030_phy_power_off(). This will block PM runtime for the SoC when no cable is connected. Fix the issue by moving PM runtime autosuspend call to happen where it gets called in twl4030_phy_power_on(). Note that this patch should not be backported to anything before commit 467d5c980709 ("usb: musb: Implement session bit based runtime PM for musb-core") as before that all the glue layers implemented their own PM.

2016-09-14phy-twl4030-usb: initialize charging-related stuff via pm_runtimeAndreas Kemnade
twl4030_phy_power_on() initializes some bits which are required for charging. As they are not set in twl4030_usb_runtime_resume() a call to pm_runtime_get_sync() is not sufficient to enable charging. This patch moves the initialization to twl4030_usb_runtime_resume() so everything needed for charging is initialized upon pm_runtime_get_sync(). That also gives improved possibilities to debug problems in that area because the relevant parts can be checked separately. Charging can be enabled without having the musb subsystem active. As a side effect this hides some bugs in musb which causes unbalanced calls to phy_power_off()/phy_power_on() so that phy->power_count becomes -1. The result is that e.g. the GTA04 phone (dm3730 + twl4030) works finally as a usb gadget again and charging is working.

setting twl->linkstat = MUSB_UNKNOWN upon error in musb_mailbox as introduced in commit 12b7db2bf8b8 ("usb: musb: Return error value from musb_mailbox") causes twl4030_usb_irq() to not detect a state change form cable connected to cable disconnected after such an error so that pm_runtime_put_autosuspend() will not be called and the usage counter gets unbalanced. Such errors happen e.g. if the omap2430 module is not (yet) loaded during plug/unplug events. This patch introduces a flag instead that indicates whether there is information for the musb_mailbox pending and calls musb_mailbox() if that flag is set.

2016-09-10phy: sun4i-usb: Use spinlock to guard phyctl register accessChen-Yu Tsai
The musb driver calls into this phy driver to disable/enable squelch detection. This function was introduced in 24fe86a617c5 ("phy: sun4i-usb: Add a sunxi specific function for setting squelch-detect"). This function in turn calls sun4i_usb_phy_write, which uses a mutex to guard the common access register.

2016-09-10phy: omap-usb2: support suspend/resumeSekhar Nori
Relying on PM-ops for shutting down PHY clocks was a bad idea since the users (e.g. USB DWC3) might not have been suspended by then. Get rid of all PM-ops. It is the sole responsibility of the PHY user to properly turn OFF and de-initialize the PHY as part of its suspend routine. Enable/disable PHY clock as part of ->init()/->exit() call respectively. With this phy_init() and phy_exit() can be called by PHY user during suspend/resume. This is similar to what is done for ti-pipe3 driver. See 31c8954efb1b ("phy: ti-pipe3: fix suspend") The pm_runtime_enable() call in omap_usb2_probe() is still required because without it, phy_create() will not enable runtime PM on the phy device it creates and phy_init() will not call pm_runtime_get_sync(). Without pm_runtime_get_sync(), ocp2scp hwmod will _not_ enable the IP and, thus, we will have abort exceptions.
