Northstar is a family of SoCs used in home routers. They have USB 2.0 and 3.0 controllers with PHYs that need to be properly initialized. This driver provides PHY init support in a generic way and can be bound with XHCI controller driver. There aren't any public datasheets from Broadcom so we can't have nice defines for all used bits. It means we just follow Broadcom's initialization procedure using their magic values. We were quite lucky actually that Broadcom put some comments in their SDK reference code explaining what given writes are responsible for.

Use the new of_usb_get_dr_mode_by_phy() function to get the dr_mode from the musb controller node instead of assuming that having an id_det gpio means otg mode, and not having one means host mode. Implement peripheral-only mode by adding a sun4i_usb_phy0_get_id_det helper which looks at the dr_mode, always registering our extcon and always monitoring vbus. If dr_mode is not specified in the dts, do not register phy0 as we then do not know how to treat it. This is actually a good thing as this means we will not be registering phy0 on devices where the otg controller is not enabled in the devicetree.

Two times out of 2000 reboots I ran into the error message "rockchip_emmc_phy_power: dllrdy timeout". Presumably there is some corner case where the DLL just takes a little longer to timeout.

2016-07-25phy: rockchip-emmc: Be tolerant to card clock of 0 in power onDouglas Anderson
It's possible that there are some reasons to turn the PHY on while the clock is 0. In this case we just won't wait for the DLL to lock. This is a bit of a stopgap until we figure out exactly when we're supposed to wait for the DLL to lock and when we're supposed to power cycle the PHY. Note: this patch should help with suspend/resume where the system will try to turn the PHY back on when the clock is 0.

2016-07-25phy: rockchip-emmc: Set phyctrl_frqsel based on card clockDouglas Anderson
The "phyctrl_frqsel" is described in the Arasan datasheet [1] as "the frequency range of DLL operation". Although the Rockchip variant of this PHY has different ranges than the reference Arasan PHY it appears as if the functionality is similar. We should set this phyctrl field properly. Note: as per Rockchip engineers, apparently the "phyctrl_frqsel" is actually only useful in HS200 / HS400 modes even though the DLL itself it used for some purposes in all modes. See the discussion in the earlier change in this series: ("mmc: sdhci-of-arasan: Always power the PHY off/on when clock changes"). In any case, it shouldn't hurt to set this always. Note that this change should allow boards to run at HS200 / HS400 speed modes while running at 100 MHz or 150 MHz. In fact, running HS400 at 150 MHz (giving 300 MB/s) is the main motivation of this series, since performance is still good but signal integrity problems are less prevelant at 150 MHz.

2016-07-25phy: rockchip-emmc: Increase lock time allowanceDouglas Anderson
Previous PHY code waited a fixed amount of time for the DLL to lock at power on time. Unfortunately, the time for the DLL to lock is actually a bit more dynamic and can be longer if the card clock is slower. Instead of waiting a fixed 30 us, let's now dynamically wait until the lock bit gets set. We'll wait up to 10 ms which should be OK even if the card clock is at the super slow 100 kHz. On its own, this change makes the PHY power on code a little more robust. Before this change the PHY was relying on the eMMC code to make sure the PHY was only powered on when the card clock was set to at least 50 MHz before, though this reliance wasn't documented anywhere. This change will be even more useful in future changes where we actually need to be able to wait for a DLL lock at slower clock speeds.

2016-07-25phy: rockchip-emmc: configure default output tap delayBrian Norris
The output tap delay controls helps maintain the hold requirements for eMMC. The exact value is dependent on the SoC and other factors, though it isn't really an exact science. But the default of 0 is not very good, as it doesn't give the eMMC much hold time, so let's bump up to 4 (approx 90 degree phase?). If we need to configure this any further (e.g., based on board or speed factors), we may need to consider a device tree representation.

If devm_add_action() fails we are explicitly calling the cleanup to free the resources allocated. Lets use the helper devm_add_action_or_reset() and return directly in case of error, as we know that the cleanup function has been already called by the helper if there was any error.

The A31 companion pmic (axp221) does not generate vbus change interrupts when the board is driving vbus, so we must poll when using the pmic for vbus-det _and_ we're driving vbus.

2016-07-04phy: rockchip-usb: should be a child device of the GRFHeiko Stuebner
The usb-phy is fully enclosed in the general register files (GRF). Therefore as seen from the device-tree it shouldn't be a separate platform-device but instead a sub-device of the GRF - using the simply-mfd mechanism. As the usb-phy is part of the kernel for some releases now, we keep the old (and now deprecated) binding for compatibility purposes.

2016-07-04phy: Add set_mode callbackDavid Lechner
The initial use for this is for PHYs that have a mode related to USB OTG. There are several SoCs (e.g. TI OMAP and DA8xx) that have a mode setting in the USB PHY to override OTG VBUS and ID signals. Of course, the enum can be expaned in the future to include modes for other types of PHYs as well.

Some of those changes are required to fix a bug introduced in -rc1, which introduces extra 'reset line checks' i.e. whether the line is shared or not. If a line is shared and the new *_shared() API is not used, the request fails with an error. This breaks USB in v4.7 for ST's platforms. Admittedly, there are some patches contained in our (MFD/Reset) immutable branch which are not true -fixes, but there isn't anything I can do about that. Rest assured though, there aren't any API 'changes'.

instead of defining all functions as static inlines, let's move them to udc-core and export them with EXPORT_SYMBOL_GPL, that way we can make sure that only GPL drivers will use them. As a side effect, it'll be nicer to add tracepoints to the gadget API. While at that, also fix Kconfig dependencies to avoid randconfig build failures.
