Add support for Generic PHY framework about Exynos SoCs. Current Exynos PCIe driver doesn't use the PHY framework, which makes it difficult to upstream the other Exynos variants because of different PHY registers.

2016-11-18phy_sun4i_usb: set_mode: Allow using set_mode to force end the current sessionHans de Goede1-4/+10
The sunxi musb has a bug where sometimes it will generate a babble error on device disconnect instead of a disconnect irq. When this happens the musb-controller switches from host mode to device mode (it clears MUSB_DEVCTL_SESSION and sets MUSB_DEVCTL_BDEVICE) and gets stuck in this state. Clearing this requires reporting Vbus low for 200 or more ms, but on some devices Vbus is simply always high (host-only mode, no Vbus control). This commit modifies sun4i_usb_phy_set_mode so that it will force end the current session when called with the current mode, before this commit calling set_mode with the current mode was a nop since id_det would stay the same resulting in the detect_work not doing anything. This allows the sunxi-musb glue to use sun4i_usb_phy_set_mode to force end the current session without changing the mode, to fixup the stuck state after a babble error.

This patch adds sysfs "role" for usb role swap. This parameter can be read and write. If you use this file as the following, you can swap the usb role. For example: 1) Connect a usb cable using 2 Salvator-x boards 2) On A-Device (ID pin is low), you input the following command: # echo peripheral > /sys/devices/platform/soc/ee080200.usb-phy/role 3) On B-Device (ID pin is high), you input the following command: # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Then, the A-device acts as a peripheral and the B-device acts as a host. Please note that A-Device must input the following command if you want the board to act as a host again. (even if you disconnect the usb cable, since id state may be the same, the A-Device keeps to act as peripheral.) # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Reviewed-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

We found that the system crashed due to 480MHz output clock of USB2 PHY was unstable after clock had been enabled by gpu module. Theoretically, 1 millisecond is a critical value for 480MHz output clock stable time, so we try to change the delay time to 1.2 millisecond to avoid this issue. And the commit ed907fb1d7c3 ("phy: rockchip-inno-usb2: correct clk_ops callback") used prepare callbacks instead of enable callbacks to support gate a clk if the operation may sleep. So we can switch from delay to sleep functions. Also fix a spelling error from "waitting" to "waiting".

2016-11-08phy: qcom-ufs-qmp-xx: Move clock and regulator init out of phy initVivek Gautam2-52/+46
The phy init is meant to do phy initialization rather than just getting the clock and regulator. Move these clock and regulator get to probe(), to make room for actual phy initialization sequence.

2016-11-08phy: qcom-ufs-qmp-xx: Discard remove callback for drivers.Vivek Gautam3-41/+0
remove() callback does a phy_power_off() only over the phy, and nothing else now. The phy_power_off() over the generic phy is called from the phy consumer, and phy provider driver should not explicitly need to call any phy ops. So discard the remove callback for qcom-ufs phy platform drivers.

Allwinner SoC's PHY 0, when used as OTG controller, have no pmu part. The code that poke some unknown bit of PMU for H3/A64 didn't check the PHY, and will cause kernel oops when PHY 0 is used. This patch will check whether the pmu is not NULL before poking.

2016-11-05phy-rockchip-pcie: remove deassert of phy_rst from exit callbackShawn Lin1-12/+1
The deassert of phy_rst from exit callback is incorrect as when doing phy_exit, we expect the phy_rst is on asserted state which was done by power_off callback, but not deasserted state. Meanwhile when disabling clk_pciephy_ref, the assert/deassert signal can't actually take effect on the phy. So let's fix it anyway.
