2021-12-14media: lirc: always send timeout reportsSean Young4-55/+5
Without timeout reports, it is impossible to decode many protocols since it is not known when the transmission ends. timeout reports are sent by default, but can be turned off. There is no reason to turn them off, and I cannot find any software which does this, so we can safely remove it. This makes the ioctl LIRC_SET_REC_TIMEOUT_REPORTS a no-op.

2021-12-14arm64: perf: Add userspace counter access disable switchRob Herring1-0/+11
Like x86, some users may want to disable userspace PMU counter altogether. Add a sysctl 'perf_user_access' file to control userspace counter access. The default is '0' which is disabled. Writing '1' enables access. Note that x86 supports globally enabling user access by writing '2' to /sys/bus/event_source/devices/cpu/rdpmc. As there's not existing userspace support to worry about, this shouldn't be necessary for Arm. It could be added later if the need arises.

2021-12-13ASoC: dt-bindings: qcom: Document qcom,msm8916-qdsp6-sndcard compatibleStephan Gerhold1-0/+42
There are two possible audio setups on MSM8916/APQ8016: Normally the audio is routed through the audio/modem DSP (covered by the qdsp6 driver). During upstreaming for the DragonBoard 410c it was decided to bypass it and instead talk directly to the audio controller using the "lpass" driver. Bypassing the DSP gives more control about the audio configuration but limits the functionality: For example, routing audio through the audio/modem DSP is strictly required for voice call audio. Also, without the special changes in the DB410c firmware other MSM8916 devices can only use the bypass as long as the modem DSP is not started. Otherwise, the firmware will assume control of the LPASS hardware block and audio is no longer functional. Add support for using the DSP audio setup instead using a new "qcom,msm8916-qdsp6-sndcard" compatible. It is basically a mixture of the apq8016-sbc-sndcard and the newer sm8250-sndcard, which uses indirect QDSP6 DAI links instead of the direct LPASS DAI links.

2021-12-13ASoC: dt-bindings: qcom: apq8016-sbc: Move to qcom,sm8250 DT schemaStephan Gerhold2-98/+81
All the Qualcomm sound card drivers use the same common device tree parsing code, so the allowed device tree nodes are almost the same for all of them. Convert the qcom,apq8016-sbc-sndcard documentation to a DT schema by adding it to the existing qcom,sm8250 schema. The only speciality of qcom,apq8016-sbc-sndcard is that it has memory resources for setting up an I/O mux. This can be handled using a conditional if statement that only requires it for the apq8016-sbc compatible.

2021-12-13kunit: tool: reconfigure when the used kunitconfig changesDaniel Latypov1-4/+4
Problem: currently, if you remove something from your kunitconfig, kunit.py will not regenerate the .config file. The same thing happens if you did --kunitconfig_add=CONFIG_KASAN=y [1] and then ran again without it. Your new run will still have KASAN. The reason is that kunit.py won't regenerate the .config file if it's a superset of the kunitconfig. This speeds it up a bit for iterating. This patch adds an additional check that forces kunit.py to regenerate the .config file if the current kunitconfig doesn't match the previous one. What this means: * deleting entries from .kunitconfig works as one would expect * dropping a --kunitconfig_add also triggers a rebuild * you can still edit .config directly to turn on new options We implement this by creating a `last_used_kunitconfig` file in the build directory (so .kunit, by default) after we generate the .config. When comparing the kconfigs, we compare python sets, so duplicates and permutations don't trip us up. The majority of this patch is adding unit tests for the existing logic and for the new case where `last_used_kunitconfig` differs.

2021-12-13Documentation: kunit: remove claims that kunit is a mocking frameworkDaniel Latypov3-5/+3
KUnit does not have any first party support for "mocking". The original RFC had some, but the code got dropped. However, the documentation patches never got updated. This fixes that. https://kunit.dev/mocking.html has a current writeup on the status quo and will hopefully be eventually folded into the in-kernel Documentation.
