2017-10-03phy: rockchip-typec: Check for errors from tcphy_phy_init()Douglas Anderson1-4/+9
The function tcphy_phy_init() could return an error but the callers weren't checking the return value. They should. In at least one case while testing I saw the message "wait pma ready timeout" which indicates that tcphy_phy_init() really could return an error and we should account for it.

2017-09-26phy: rockchip-typec: Don't set the aux voltage swing to 400 mVDouglas Anderson1-3/+4
On rk3399-gru-kevin there are some cases where we're seeing AUX CH failures when trying to do DisplayPort over type C. Problems are intermittent and don't reproduce all the time. Problems are often bursty and failures persist for several seconds before going away. The failure case I focused on is: * A particular type C to HDMI adapter. * One orientation (flip mode) of that adapter. * Easier to see failures when something is plugged into the _other type C port at the same time. * Problems reproduce on both type C ports (left and right side). Ironically problems also stop reproducing when I solder wires onto the AUX CH signals on a port (even if no scope is connected to the signals). In this case, problems only stop reproducing on the port with the wires connected. From the above it appears that something about the signaling on the aux channel is marginal and any slight differences can bring us over the edge to failure. It turns out that we can fix our problems by just increasing the voltage swing of the AUX CH, giving us a bunch of extra margin. In DP up to version 1.2 the voltage swing on the aux channel was specced as .29 V to 1.38 V. In DP version 1.3 the aux channel voltage was tightened to be between .29 V and .40 V, but it clarifies that it really only needs the lower voltage when operating at the highest speed (HBR3 mode). So right now we are trying to use a voltage that technically should be valid for all versions of the spec (including version 1.3 when transmitting at HBR3). That would be great to do if it worked reliably. ...but it doesn't seem to. It turns out that if you continue to read through the DP part of the rk3399 TRM and other parts of the type C PHY spec you'll find out that while the rk3399 does support DP 1.3, it doesn't support HBR3. The docs specifically say "RBR, HBR and HBR2 data rates only". Thus there is actually no requirement to support an AUX CH swing of .4 V. Even if there is no actual requirement to support the tighter voltage swing, one could possibly argue that we should support it anyway. The DP spec clarifies that the lower voltage on the AUX CH will reduce cross talk in some cases and that seems like it could be beneficial even at the lower bit rates. At the moment, though, we are seeing problems with the AUX CH and not on the other lines. Also, checking another known working and similar laptop shows that the other laptop runs the AUX channel at a higher voltage. Other notes: * Looking at measurements done on the AUX CH we weren't actually compliant with the DP 1.3 spec anyway. AUX CH peek-to-peek voltage was measured on rk3399-gru-kevin as .466 V which is > .4 V. * With this new patch the AUX channel isn't actually 1.0 V, but it has been confirmed that the signal is better and has more margin. Eye diagram passes. * If someone were truly an expert in the Type C PHY and in DisplayPort signaling they might be able to make things work and keep the voltage at < .4 V. The Type C PHY seems to have a plethora of tuning knobs that could almost certainly improve the signal integrity. Some of these things (like enabling tx_fcm_full_margin) even seem to fix my problems. However, lacking expertise I can't say whether this is a better or worse solution. Tightening signals to give cleaner waveforms can often have adverse affects, like increasing EMI or adding noise to other signals. I'd rather not tune things like this without a healthy application of expertise that I don't have.

2017-09-26phy: rockchip-typec: Set the AUX channel flip state earlierDouglas Anderson1-20/+42
On some DP monitors we found that setting the wrong flip state on the AUX channel could cause the monitor to stop asserting HotPlug Detect (HPD). Setting the right flip state caused these monitors to start asserting HotPlug Detect again. Here's what we believe was happening: * We'd plug in the monitor and we'd see HPD assert * We'd quickly see HPD deassert * The kernel would try to init the type C PHY but would init it in USB mode (because there was a peripheral there but no HPD) * Because the kernel never set the flip mode properly we'd never see the HPD come back. With this change, we'll still see HPD disappear (we don't think there's anything we can do about that), but then it will come back. Overall we can say that it's sane to set the AUX channel flip state even when HPD is not asserted. NOTE: to make this change possible, I needed to do a bit of cleanup to the tcphy_dp_aux_calibration() function so that it doesn't ever clobber the FLIP state. This made it very obvious that a line of code documented as "setting bit 12" also did a bunch of other magic, undocumented stuff. For now I'll just break out the bits and add a comment that this is black magic and we'll try to document tcphy_dp_aux_calibration() better in a future CL. ALSO NOTE: the old function used to write a bunch of hardcoded values in _some_ cases instead of doing a read-modify-write. One could possibly assert that these could have had (beneficial) side effects and thus with this new code (which always does read-modify-write) we could have a bug. We shouldn't need to worry, though, since in the old code tcphy_dp_aux_calibration() was always called following the de-assertion of "reset" the the type C PHY. ...so the type C PHY was always in default state. TX_ANA_CTRL_REG_1 is documented to be 0x0 after reset. This was also confirmed by printk.

2017-08-30phy: add the mvebu cp110 comphy driverAntoine Tenart3-0/+656
On the CP110 unit, which can be found on various Marvell platforms such as the 7k and 8k (currently), a comphy (common PHYs) hardware block can be found. This block provides a number of PHYs which can be used in various modes by other controllers (network, SATA ...). These common PHYs must be configured for the controllers using them to work correctly either at boot time, or when the system runs to switch the mode used. This patch adds a driver for this comphy hardware block, providing callbacks for the its PHYs so that consumers can configure the modes used. As of this commit, two modes are supported by the comphy driver: sgmii and 10gkr.

Add new 'extcon-usbc-cros-ec.c' driver - ChromeOS Embedded Controller extcon driver supports the detection of the Display Port (EXTCON_DISP_DP) through USB C-type and contol it. 2. Update extcon core - Modify the description for both functions and structures in order to improve the readability and give the more correct guide about the role of functions because there are different explanation even if the same arguments. - Keep the indentation with tab instead of space - Remove the following deprecated extcon API. The deprecated API are exchanged on all of linux tree. : extcon_get_cable_state_() -> extcon_get_state() : extcon_set_cable_state_() -> extcon_set_state_sync() 3. Include the two immutable branch as following: - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory. - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API because the usb/phy driver usese the deprecated extcon API. So, this immutable branch alters the extcon API and then remove them from extcon. 4. Fix minor issue of extcon driver - Fix the MHL detection on extcon-max77693.c - Convert to using %pOF instead of full_name on extcon.c - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c
