2020-02-10qmi_wwan: re-add DW5821e pre-production variantBjørn Mork
Commit f25e1392fdb5 removed the support for the pre-production variant of the Dell DW5821e to avoid probing another USB interface unnecessarily. However, the pre-production samples are found in the wild, and this lack of support is causing problems for users of such samples. It is therefore necessary to support both variants. Matching on both interfaces 0 and 1 is not expected to cause any problem with either variant, as only the QMI function will be probed successfully on either. Interface 1 will be rejected based on the HID class for the production variant: T: Bus=01 Lev=03 Prnt=04 Port=00 Cnt=01 Dev#= 16 Spd=480 MxCh= 0 D: Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 2 P: Vendor=413c ProdID=81d7 Rev=03.18 S: Manufacturer=DELL S: Product=DW5821e Snapdragon X20 LTE S: SerialNumber=0123456789ABCDEF C: #Ifs= 6 Cfg#= 1 Atr=a0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)

2020-02-10drm/i915: Make a copy of the ggtt view for slave planeVille Syrjälä
intel_prepare_plane_fb() will always pin plane_state->hw.fb whenever it is present. We copy that from the master plane to the slave plane, but we fail to copy the corresponding ggtt view. Thus when it comes time to pin the slave plane's fb we use some stale ggtt view left over from the last time the plane was used as a non-slave plane. If that previous use involved 90/270 degree rotation or remapping we'll try to shuffle the pages of the new fb around accordingingly. However the new fb may be backed by a bo with less pages than what the ggtt view rotation/remapped info requires, and so we we trip a GEM_BUG(). Steps to reproduce on icl: 1. plane 1: whatever plane 6: largish !NV12 fb + 90 degree rotation 2. plane 1: smallish NV12 fb plane 6: make invisible so it gets slaved to plane 1 3.

2020-02-10s390/qdio: simplify ACK trackingJulian Wiedmann
Current code uses a 'polling' flag to keep track of whether an Input Queue has any ACKed SBALs. QEBSM devices might have multiple ACKed SBALs, and those are tracked separately with 'ack_count'. By also setting ack_count for non-QEBSM devices (to a fixed value of 1), we can use 'ack_count != 0' as replacement for the polling flag.

2020-02-10s390/zcrypt: fix card and queue total counter wrapHarald Freudenberger

This patch introduces uint64 counters which should hold much longer but still may wrap. The sysfs attributes request_count for card and queue also used only %ld and now display the counter value with %llu. This is not a security relevant fix.

2020-02-10drm/bridge: tc358767: fix poll timeoutsTomi Valkeinen
Link training fails with: Link training timeout waiting for LT_LOOPDONE! main link enable error: -110 This is caused by too tight timeouts, which were changed recently in aa92213f388b ("drm/bridge: tc358767: Simplify polling in tc_link_training()"). With a quick glance, the commit does not change the timeouts. However, the method of delaying/sleeping is different, and as the timeout in the previous implementation was not explicit, the new version in practice has much tighter timeout. The same change was made to other parts in the driver, but the link training timeout is the only one I have seen causing issues. Nevertheless, 1 us sleep is not very sane, and the timeouts look pretty tight, so lets fix all the timeouts. One exception was the aux busy poll, where the poll sleep was much longer than necessary (or optimal). I measured the times on my setup, and now the sleep times are set to such values that they result in multiple loops, but not too many (say, 5-10 loops). The timeouts were all increased to 100ms, which should be more than enough for all of these, but in case of bad errors, shouldn't stop the driver as multi-second timeouts could do.

2020-02-10USB: serial: ch341: fix receiver regressionJohan Hovold
While assumed not to make a difference, not using the factor-2 prescaler makes the receiver more susceptible to errors. Specifically, there have been reports of problems with devices that cannot generate a 115200 rate with a smaller error than 2.1% (e.g. 117647 bps). But this can also be reproduced with a low-speed RS232 tranceiver at 115200 when the input rate matches the nominal rate. So whenever possible, enable the factor-2 prescaler and halve the divisor in order to use settings closer to that of the previous algorithm.

Since commit 742379c0c4001 ("drm/i915: Start chopping up the GPU error capture"), function 'i915_error_state_store' was defined and used with only one parameter. But if no 'CONFIG_DRM_I915_CAPTURE_ERROR', this function was defined with two parameter. This may lead compile error. This patch fix it.

2020-02-09drm/i915: Fix post-fastset modeset check for port syncVille Syrjälä
The post-fastset "does anyone still need a full modeset?" for port sync looks busted. The outer loop bails out of a full modeset is still needed by the current crtc, and then we skip forcing a full modeset on the related crtcs. That's totally the opposite of what we want. The MST path has the logic mostly the other way around so it looks correct. To fix the port sync case let's follow the MST logic for both. So, if the current crtc already needs a modeset we do nothing. otherwise we check if any of the related crtcs needs a modeset, and if so we force a full modeset for the current crtc. And while at let's change the else if to a plain if to so we don't have needless coupling between the MST and port sync checks.

2020-02-08Fix up remaining devm_ioremap_nocache() in SGI IOC3 8250 UART driverLinus Torvalds
This is a merge error on my part - the driver was merged into mainline by commit c5951e7c8ee5 ("Merge tag 'mips_5.6' of git://../mips/linux") over a week ago, but nobody apparently noticed that it didn't actually build due to still having a reference to the devm_ioremap_nocache() function, removed a few days earlier through commit 6a1000bd2703 ("Merge tag 'ioremap-5.6' of git://../ioremap"). Apparently this didn't get any build testing anywhere. Not perhaps all that surprising: it's restricted to 64-bit MIPS only, and only with the new SGI_MFD_IOC3 support enabled. I only noticed because the ioremap conflicts in the ARM SoC driver update made me check there weren't any others hiding, and I found this one.

2020-02-08net: thunderx: use proper interface type for RGMIITim Harvey
The configuration of the OCTEONTX XCV_DLL_CTL register via xcv_init_hw() is such that the RGMII RX delay is bypassed leaving the RGMII TX delay enabled in the MAC: /* Configure DLL - enable or bypass * TX no bypass, RX bypass */ cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL); cfg &= ~0xFF03; cfg |= CLKRX_BYP; writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL); This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID and not PHY_INTERFACE_MODE_RGMII. Fixing this allows RGMII PHY drivers to do the right thing (enable RX delay in the PHY) instead of erroneously enabling both delays in the PHY.

2020-02-08irqchip/gic-v3-its: Rename VPENDBASER/VPROPBASER accessorsZenghui Yu
V{PEND,PROP}BASER registers are actually located in VLPI_base frame of the *redistributor*. Rename their accessors to reflect this fact. No functional changes.

2020-02-08irqchip/gic-v3-its: Remove superfluous WARN_ONZenghui Yu
"ITS virtual pending table not cleaning" is already complained inside its_clear_vpend_valid(), there's no need to trigger a WARN_ON again.

2020-02-08irqchip/gic-v4.1: Drop 'tmp' in inherit_vpe_l1_table_from_rd()Zenghui Yu
The variable 'tmp' in inherit_vpe_l1_table_from_rd() is actually not needed, drop it. Signed-off-by: Zenghui Yu <yuzenghui@huawei.com> Signed-off-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20200206075711.1275-5-yuzenghui@huawei.com
2020-02-08irqchip/gic-v4.1: Ensure L2 vPE table is allocated at RD levelZenghui Yu
In GICv4, we will ensure that level2 vPE table memory is allocated for the specified vpe_id on all v4 ITS, in its_alloc_vpe_table(). This still works well for the typical GICv4.1 implementation, where the new vPE table is shared between the ITSs and the RDs. To make it explicit, let us introduce allocate_vpe_l2_table() to make sure that the L2 tables are allocated on all v4.1 RDs. We're likely not need to allocate memory in it because the vPE table is shared and (L2 table is) already allocated at ITS level, except for the case where the ITS doesn't share anything (say SVPET == 0, practically unlikely but architecturally allowed). The implementation of allocate_vpe_l2_table() is mostly copied from its_alloc_table_entry().
