This patch series continues the usb chipidea rewrite for Qualcommm platforms. I've dropped the patches that were applied to Peter's tree for chipidea. Now the phy drivers are left, along with the patch to call phy_set_mode() at the right place. I've left the HSIC phy driver here, because it wasn't merged in the last round. Nothing has changed in that driver, so I believe it is ready to be merged now. The chipidea patch is independent and can be merged without causing any dependency with the phy tree. Patches based on v4.10-rc1 + first 22 patches from v5. Full branch is here[1]. Changes from v7: * Dropped set_vbus() callback (Kishon) * Made phy_set_mode() generic and moved into ci_platform_configure() (Peter) Changes from v6: * Dropped first 22 applied patches * Rewrote phy_set_mode() patch to be msm specific * New set_vbus() callback in phy framework * Updated HS phy driver for set_vbus() callback Changes from v5: * Replaced "Emulate OTGSC interrupt enable path" patch with a patch from Peter * Updated HS phy driver to support set_mode callback to handle pullup * New patch to set the mode to device or host in chipidea udc pullup function to toggle the pullup for HS mode * New patch to drop lock around event_notify callback to avoid lockdep issues * Removal of extcon usage from HS phy driver * Picked up acks from Heikki and Peter on ULPI core patch Changes from v4: * Picked up Acks from Rob * Updated HS phy init sequence DT property to restrict it to offsets Changes from v3: * Picked up Acks from Peter * Updated extcon consolidation patch per Peter's comments * Folded in simplification from Heikki for ULPI DT matching Changes from v2: * Added SoC specific compatibles in phy bindings * Dropped AVVIS patch for OTG statemachine * New patch to consolidate extcon handlers * Picked up Acks from Peter * Rebased onto v4.8-rc1 * Reworked ULPI OF code to look at vid == 0 instead of pid == 0 * Dropped ULPI bindings for vid and pid overrides Changes from v1: * Reworked ULPI device probing to keep using vendor/product ids that come from DT if needed and falls back to OF style match when product id is 0 * PHY init later patch was rejected so that moved to a quirk flag and the msm wrapper started managing the phy on/off * Updated clk requirements for HSIC phy in binding doc * Added optional clk in wrapper for "housekeeping" found on older qcom platforms * Bug fix to OTGSC polling function * Changed runtime PM patch to set as active instead of get/put TODO: * DMA fails on arm64 so we need something like [2] to make it work. * The db410c needs a driver to toggle the onboard switch to connect the usb hub instead of micro port when the usb cable is disconnected. I've sent a patch set for this[3], which needs some further discussion/development. The current plan is to reintroduce the usb mux framework. * apq8064 platforms need a vbus regulator to really use otg and I haven't tried out the RPM based regulators yet * The HSIC phy on the apq8074 dragonboard is connected to a usb4604 device which requires the i2c driver to probe and send an i2c sequence before the HSIC controller enumerates or HSIC doesn't work. Right now I have a hack to force the controller to probe defer once so that usb4604 probes first. This needs a more proper solution like having the DT describe a linkage between the controller and the usb device so we can enforce probe ordering. My current plan is to use DT graphs/endpoints for this.
