2022-06-19ARM: dts: imx7d-smegw01: Fix the SDIO descriptionFabio Estevam1-3/+1
usdhc2 is connected to a Wifi chip that is powered by a 3.3V supply. Pass the "no-1-8-v" property to guarantee that no communication is made at 1.8V. While at it, also remove the unnecessary properties: "cap-sd-highspeed", "sd-uhs-ddr50", and "mmc-ddr-1_8v".

2022-06-19ARM: dts: imx6: skov: add pwm-regulator to control the panel's VCOMUlrich Ölmann2-0/+16
Skov's i.MX6 based boards come in different flavors which have different panels attached. For optimal contrast experience each panel type needs an individual common voltage (VCOM) to drive its TFT backplane. The latter is generated by an LCD bias supply IC controlled by a pwm as input signal. Introduce a pwm- regulator to describe this hardware property and parameterize it appropriately for the different boards.

2022-06-18ext4: fix up test_dummy_encryption handling for new mount APIEric Biggers1-63/+71
Since ext4 was converted to the new mount API, the test_dummy_encryption mount option isn't being handled entirely correctly, because the needed fscrypt_set_test_dummy_encryption() helper function combines parsing/checking/applying into one function. That doesn't work well with the new mount API, which split these into separate steps. This was sort of okay anyway, due to the parsing logic that was copied from fscrypt_set_test_dummy_encryption() into ext4_parse_param(), combined with an additional check in ext4_check_test_dummy_encryption(). However, these overlooked the case of changing the value of test_dummy_encryption on remount, which isn't allowed but ext4 wasn't detecting until ext4_apply_options() when it's too late to fail. Another bug is that if test_dummy_encryption was specified multiple times with an argument, memory was leaked. Fix this up properly by using the new helper functions that allow splitting up the parse/check/apply steps for test_dummy_encryption.

2022-06-18drm/msm/dp: force link training for display resolution changeKuogee Hsieh3-16/+32
Display resolution change is implemented through drm modeset. Older modeset (resolution) has to be disabled first before newer modeset (resolution) can be enabled. Display disable will turn off both pixel clock and main link clock so that main link have to be re-trained during display enable to have new video stream flow again. At current implementation, display enable function manually kicks up irq_hpd_handle which will read panel link status and start link training if link status is not in sync state. However, there is rare case that a particular panel links status keep staying in sync for some period of time after main link had been shut down previously at display disabled. In this case, main link retraining will not be executed by irq_hdp_handle(). Hence video stream of newer display resolution will fail to be transmitted to panel due to main link is not in sync between host and panel. This patch will bypass irq_hpd_handle() in favor of directly call dp_ctrl_on_stream() to always perform link training in regardless of main link status. So that no unexpected exception resolution change failure cases will happen. Also this implementation are more efficient than manual kicking off irq_hpd_handle function.

2022-06-18drm/msm/dpu: limit wb modes based on max_mixer_widthAbhinav Kumar1-1/+8
As explained in [1], using max_linewidth to limit the modes does not seem to remove 4K modes on chipsets such as sm8250 where the max_linewidth actually supports 4k. This would have been alright if dual SSPP support was present but otherwise fails the per SSPP bandwidth check. The ideal way to implement this would be to filter out the modes which will exceed the bandwidth check by computing it. But this would be an exhaustive solution till we have dual SSPP support. Let's instead use max_mixer_width to limit the modes. max_mixer_width still remains 2560 on sm8250 so even if the max_linewidth is 4096, the only way 4k modes could have been supported is to have source split enabled on the SSPP. Since source split support is not enabled yet in DPU driver, enforce max_mixer_width as the upper limit on the modes.

2022-06-18drm/msm: Drop update_fences()Rob Clark2-23/+7
I noticed while looking at some traces, that we could miss calls to msm_update_fence(), as the irq could have raced with retire_submits() which could have already popped the last submit on a ring out of the queue of in-flight submits. But walking the list of submits in the irq handler isn't really needed, as dma_fence_is_signaled() will dtrt. So lets just drop it entirely. v2: use spin_lock_irqsave/restore as we are no longer protected by the spin_lock_irqsave/restore() in update_fences() Reported-by: Steev Klimaszewski <steev@kali.org> Fixes: 95d1deb02a9c ("drm/msm/gem: Add fenced vma unpin") Signed-off-by: Rob Clark <robdclark@chromium.org> Tested-by: Steev Klimaszewski <steev@kali.org> Patchwork: https://patchwork.freedesktop.org/patch/490136/ Link: https://lore.kernel.org/r/20220618161120.3451993-1-robdclark@gmail.com

In addition, ax25_dev_device_up() unconditionally calls ax25_register_dev_sysctl(), which already allocates with GFP_KERNEL.

2022-06-17net/sched: sch_netem: Fix arithmetic in netem_dump() for 32-bit platformsPeilin Ye1-2/+2
As reported by Yuming, currently tc always show a latency of UINT_MAX for netem Qdisc's on 32-bit platforms: $ tc qdisc add dev dummy0 root netem latency 100ms $ tc qdisc show dev dummy0 qdisc netem 8001: root refcnt 2 limit 1000 delay 275s 275s ^^^^^^^^^^^^^^^^ Let us take a closer look at netem_dump(): qopt.latency = min_t(psched_tdiff_t, PSCHED_NS2TICKS(q->latency, UINT_MAX); qopt.latency is __u32, psched_tdiff_t is signed long, (psched_tdiff_t)(UINT_MAX) is negative for 32-bit platforms, so qopt.latency is always UINT_MAX. Fix it by using psched_time_t (u64) instead. Note: confusingly, users have two ways to specify 'latency': 1. normally, via '__u32 latency' in struct tc_netem_qopt; 2. via the TCA_NETEM_LATENCY64 attribute, which is s64. For the second case, theoretically 'latency' could be negative. This patch ignores that corner case, since it is broken (i.e. assigning a negative s64 to __u32) anyways, and should be handled separately. Thanks Ted Lin for the analysis [1] .
