Kbuilt test robot reported: drivers/phy/motorola/phy-mapphone-mdm6600.c:188:16: warning: is used uninitialized in this function [-Wuninitialized] val |= values[i] << i; ~~~~~~^~~ Looking at the phy_mdm6600_status() values does get initialized by gpiod_get_array_value_cansleep(), but we are using wrong enum in that function. Let's fix the use, both end up being three though so urgent rush on this one AFAIK.

2018-05-20T16:21:30Z

QMP V3 UNI PHY is a single lane USB3 PHY without support for DisplayPort (DP). Main difference from DP combo QMPv3 PHY is that UNI PHY doesn't have dual RX/TX lanes and no separate DP_COM block for configuration related to type-c or DP. Also remove "qcom,qmp-v3-usb3-phy" compatible string which was earlier added for sdm845 only as there wouldn't be any user of same.

phy: qcom-qmp: Enable pipe_clk before PHY initialization

2018-05-20T16:21:27Z

QMP PHY for USB/PCIE requires pipe_clk for locking of retime buffers at the pipe interface. Driver checks for PHY_STATUS without enabling pipe_clk due to which phy_init() fails with initialization timeout. Though pipe_clk is output from PHY (after PLL is programmed during initialization sequence) to GCC clock_ctl and then fed back to PHY but for PHY_STATUS register to reflect successful initialization pipe_clk from GCC must be present. Since, clock driver now ignores status_check for pipe_clk on clk_enable/disable, driver can safely enable/disable pipe_clk from phy_init/exit.

phy: mapphone-mdm6600: Add runtime PM support for n_gsm on USB suspend

2018-05-20T16:21:24Z

We can suspend the mdm6600 over USB via sysfs and then mdm6600 enters a low-power idle mode. In the low-power mode, mdm6600 radio and n_gsm uart are functional but we need to use USB mode0 GPIO pin to send a wake-up pulse to the modem to talk with it over n_gsm. As the GPIO mode0 line is dual purposed and and also needed by the USB PHY driver to boot mdm6600 into the correct USB mode, let's also manage the wake-up GPIO in the USB PHY driver. For the USB PHY idle, there does not anything specific we need to do for runtime PM after getting the PHY configured. The PHY framework already idles the USB PHY when not in use separately from the mdm6600 state. It seems that it takes about 100 - 200ms for mdm6600 to wake up from the low-power idle mode. And then mdm6600 stays awake about 1.2s until it needs to be kicked again. The mdm6600 status GPIO pins don't seem to change state when mdm6600 changes between normal and idle mode. Let's manage the mdm6600 mode with runtime PM. If phy-mapphone-mdm6600 sysfs entry for power/control is set to "on", we keep mdm6600 out of idle by kicking the GPIO line. If the entry is set to "auto" we let mdm6600 enter low-power state.
