2017-10-23PCI: dra7xx: Create functional dependency between PCIe and PHYKishon Vijay Abraham I1-0/+16
PCI core access configuration space registers in resume_noirq callbacks. In the case of dra7xx, PIPE3 PHY connected to PCIe controller has to be enabled before accessing configuration space registers. Since PIPE3 PHY is enabled by only configuring control module registers, no aborts has been observed so far (though during noirq stage, interface clock of PIPE3 PHY is not enabled). With new TRM updates, PIPE3 PHY has to be initialized (PIPE3 PHY registers has to be accessed) as well which requires the interface clock of PIPE3 PHY to be enabled. The interface clock of PIPE3 PHY is derived from OCP2SCP and hence PCIe PHY is modeled as a child of OCP2SCP. Since pm_runtime is not enabled during noirq stage, pm_runtime_get_sync done in phy_init doesn't enable OCP2SCP clocks resulting in abort when PIPE3 PHY registers are accessed. Create a function dependency between PCIe and PHY here to make sure PCIe is suspended before PCIe PHY/OCP2SCP and resumed after PCIe PHY/OCP2SCP.

2017-10-23phy: rockchip-typec: Avoid magic numbers + add delays in aux calibDouglas Anderson1-39/+163
NOTE: nothing is known to be fixed by this change, but it does enforce some delays that are documented to be necessary. Possibly this could fix some corner cases. The function tcphy_dp_aux_calibration(), like most of the functions in the type C PHY, is mostly undocumented and filled with mysterious, hardcoded numbers. Let's attempt to try to document some of these numbers and clean the function up a little bit. Here's the actual cleanup that happened here: 1. All magic numbers were replaced with bit definitions. 2. For registers that we modify multiple times I now keep track of the value of the register rather than randomly doing a read/modify/write or just hardcoding a new number based on knowing what the old number was. 3. Delay 10 ms (vs 1 ms) after writing the calibration code. No idea if this is important but it matches the example in the docs. 4. Whenever setting a "delayed" version of a signal always put an explicit delay in the code. No known problems were seen without this delay but it seems wise to have it. Whenever a delay of "at least 100 ns" was specified I used a delay of 1 us. 5. Added comments to some of the bits of code. 6. Removed duplicate setting of TX_ANA_CTRL_REG_5 (to 0) 7. Moved setting of TX_ANA_CTRL_REG_3 to the same place it was in the sample code. Note that TX_ANA_CTRL_REG_3 ought to be initted to 0 (and elsewhere we assume that we just got a reset), but it seems fine to be explicit. 8. Treats the calibration code as a 7-bit two's complement number. This isn't strictly required, but seems slightly cleaner. The docs say "treat this as a two's complement number, but it should never be negative". If we ever read the "adjustment" codes as documented then perhaps the two's complement bit will matter more. There are still a few weird / mysterious things around aux init and this doesn't attempt to fix all of them. Mostly it's aimed at doing changes that should be _very_ safe and add a lot of clarity. Things specifically not done: A) Resolve the fact that some registers are read/modify/write and others are explicitly initted to a value. We always call tcphy_dp_aux_calibration() right after resetting the PHY so it's probably not critical, but it's a little weird that the code is inconsistent. B) Fully resolve the documented init sequence with the current one. We still have a few mystery steps and we also leave out turning on TXDA_DRV_LDO_BG_FB_EN and TXDA_DRV_LDO_BG_REF_EN, which is in the sample code. C) Clean things up to read all the bits of the calibration code. This will hopefully come in a followup change. This also doesn't attempt to document any of the other parts of the PHY--just the aux init which is all I got docs for.

It will be set to one of the following values: - "host" - host mode - "peripheral " - device mode - "drd" - switch between device and host mode based on installed device - "typec-pd" - device/host mode is controller by the USB Type-C PD protocol. If "dr_mode" is "drd" - "drd_select" (RW) - It will be set to one of the following values: - "host" - force host mode - "device" - force device mode - "auto" - allow normal auto selection of host/device based on inserted USB device Signed-off-by: Al Cooper <alcooperx@gmail.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

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.

2017-09-16firmware: Restore support for built-in firmwareMarkus Trippelsdorf4-5/+71
Commit 5620a0d1aac ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum. The default for EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

2017-09-16mlxsw: spectrum_router: Only handle IPv4 and IPv6 eventsIdo Schimmel1-1/+2
The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.

2017-09-15sctp: do not mark sk dumped when inet_sctp_diag_fill returns errXin Long1-1/+0
sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill returns err, in which case it shouldn't mark sk dumped by setting cb->args[3] as 1 in sctp_sock_dump(). Otherwise, it could cause some asocs to have no parent's sk dumped in 'ss --sctp'. So this patch is to not set cb->args[3] when inet_sctp_diag_fill() returns err in sctp_sock_dump().
