2022-10-17ASoC: codecs: jz4725b: add missed microphone widgetsSiarhei Volkau
Microphone input can be single ended or differential, although known SoCs with that codec expose MIC1P only. Also there is 20dB mic boost in the Mic1 path.

2022-10-17ASoC: codecs: jz4725b: add missed Mixer inputsSiarhei Volkau
The Mixer couples analog input from 4 sources (DAC, Line In, Mic 1, Mic 2) each input has its own gain & mute controls. At the moment only DAC is implemented fully and Line In path can be switched on/off. The patch implements Mic 1 and Mic 2 paths and fully implements Line In path. Manual states that these controls (16.6.3.3 Programmable attenuation: GOi) gain varies from -22.5dB to +6.0dB with 1.5dB step. Also there's extra values below the minimum, but they behave the same as the minimum value.

2022-10-17ASoC: codecs: jz4725b: use right control for Master PlaybackSiarhei Volkau
At the moment DAC control is used as Master Playback control, this is incorrect as DAC's output goes to a Mixer. The Mixer couples analog input from 4 sources (DAC, Line In, Mic 1, Mic 2) each input has its own gain & mute controls. Output of the Mixer goes to Output Stage control which is the best suite for the new Playback Master. However, it doesn't have mute capability. The patch implements Output Stage control as a new master and renames old Master to DAC. Rest of mixer inputs will be implemented in the next patch in the series. Manual states that Output stage control (16.6.3.5 Programmable output amplifier: PGAT) gain varies from -33.5dB to +4.5dB, gain step isn't fixed and has 3 opts.

2022-10-17ASoC: codecs: jz4725b: use right control for Capture VolumeSiarhei Volkau
Line In Bypass control is used as Master Capture at the moment this is completely incorrect. Current control routed to Mixer instead of ADC, thus can't affect Capture path. ADC control shall be used instead. ADC volume control parameters are different, so the patch fixes that as well. Manual says (16.6.3.2 Programmable input attenuation amplifier: PGATM) that gain varies in range 0dB..22.5dB with 1.5dB step.

2022-10-17ASoC: codecs: jz4725b: fix reported volume for Master ctlSiarhei Volkau
DAC volume control is the Master Playback Volume at the moment and it reports wrong levels in alsamixer and other alsa apps. The patch fixes that, as stated in manual on the jz4725b SoC (16.6.3.4 Programmable attenuation: GOD) the ctl range varies from -22.5dB to 0dB with 1.5dB step.

2022-10-17ASoC: kirkwood: enable Kirkwood driver for Armada 38x platformsMarcin Wojtas
The audio unit of Marvell Armada38x SoC is similar to the ones comprised by other Marvell SoCs (Kirkwood, Dove and Armada 370). Therefore KW audio driver can be used to support it and this commit adds new compatible string to identify Armada 38x variant. Two new memory regions are added: first one for PLL configuration and the second one for choosing one of audio I/O modes (I2S or S/PDIF). For the latter purpose a new optional DT property is added ('spdif-mode'). kirkwood-i2s driver is extended by adding a new init function for Armada 38x flavor and also a routine that enables PLL output (i.e. MCLK) configuration.

The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull more perf tools updates from Arnaldo Carvalho de Melo: - Use BPF CO-RE (Compile Once, Run Everywhere) to support old kernels when using bperf (perf BPF based counters) with cgroups. - Support HiSilicon PCIe Performance Monitoring Unit (PMU), that monitors bandwidth, latency, bus utilization and buffer occupancy. Documented in Documentation/admin-guide/perf/hisi-pcie-pmu.rst. - User space tasks can migrate between CPUs, so when tracing selected CPUs, system-wide sideband is still needed, fix it in the setup of Intel PT on hybrid systems. - Fix metricgroups title message in 'perf list', it should state that the metrics groups are to be used with the '-M' option, not '-e'. - Sync the msr-index.h copy with the kernel sources, adding support for using "AMD64_TSC_RATIO" in filter expressions in 'perf trace' as well as decoding it when printing the MSR tracepoint arguments. - Fix program header size and alignment when generating a JIT ELF in 'perf inject'. - Add multiple new Intel PT 'perf test' entries, including a jitdump one. - Fix the 'perf test' entries for 'perf stat' CSV and JSON output when running on PowerPC due to an invalid topology number in that arch. - Fix the 'perf test' for arm_coresight failures on the ARM Juno system. - Fix the 'perf test' attr entry for PERF_FORMAT_LOST, adding this option to the or expression expected in the intercepted perf_event_open() syscall. - Add missing condition flags ('hs', 'lo', 'vc', 'vs') for arm64 in the 'perf annotate' asm parser. - Fix 'perf mem record -C' option processing, it was being chopped up when preparing the underlying 'perf record -e mem-events' and thus being ignored, requiring using '-- -C CPUs' as a workaround. - Improvements and tidy ups for 'perf test' shell infra. - Fix Intel PT information printing segfault in uClibc, where a NULL format was being passed to fprintf. * tag 'perf-tools-for-v6.1-2-2022-10-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (23 commits) tools arch x86: Sync the msr-index.h copy with the kernel sources perf auxtrace arm64: Add support for parsing HiSilicon PCIe Trace packet perf auxtrace arm64: Add support for HiSilicon PCIe Tune and Trace device driver perf auxtrace arm: Refactor event list iteration in auxtrace_record__init() perf tests stat+json_output: Include sanity check for topology perf tests stat+csv_output: Include sanity check for topology perf intel-pt: Fix system_wide dummy event for hybrid perf intel-pt: Fix segfault in intel_pt_print_info() with uClibc perf test: Fix attr tests for PERF_FORMAT_LOST perf test: test_intel_pt.sh: Add 9 tests perf inject: Fix GEN_ELF_TEXT_OFFSET for jit perf test: test_intel_pt.sh: Add jitdump test perf test: test_intel_pt.sh: Tidy some alignment perf test: test_intel_pt.sh: Print a message when skipping kernel tracing perf test: test_intel_pt.sh: Tidy some perf record options perf test: test_intel_pt.sh: Fix return checking again perf: Skip and warn on unknown format 'configN' attrs perf list: Fix metricgroups title message perf mem: Fix -C option behavior for perf mem record perf annotate: Add missing condition flags for arm64 ...

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull more clk updates from Stephen Boyd: "This is the final part of the clk patches for this merge window. The clk rate range series needed another week to fully bake. Maxime fixed the bug that broke clk notifiers and prevented this from being included in the first pull request. He also added a unit test on top to make sure it doesn't break so easily again. The majority of the series fixes up how the clk_set_rate_*() APIs work, particularly around when the rate constraints are dropped and how they move around when reparenting clks. Overall it's a much needed improvement to the clk rate range APIs that used to be pretty broken if you looked sideways. Beyond the core changes there are a few driver fixes for a compilation issue or improper data causing clks to fail to register or have the wrong parents. These are good to get in before the first -rc so that the system actually boots on the affected devices" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (31 commits) clk: tegra: Fix Tegra PWM parent clock clk: at91: fix the build with binutils 2.27 clk: qcom: gcc-msm8660: Drop hardcoded fixed board clocks clk: mediatek: clk-mux: Add .determine_rate() callback clk: tests: Add tests for notifiers clk: Update req_rate on __clk_recalc_rates() clk: tests: Add missing test case for ranges clk: qcom: clk-rcg2: Take clock boundaries into consideration for gfx3d clk: Introduce the clk_hw_get_rate_range function clk: Zero the clk_rate_request structure clk: Stop forwarding clk_rate_requests to the parent clk: Constify clk_has_parent() clk: Introduce clk_core_has_parent() clk: Switch from __clk_determine_rate to clk_core_round_rate_nolock clk: Add our request boundaries in clk_core_init_rate_req clk: Introduce clk_hw_init_rate_request() clk: Move clk_core_init_rate_req() from clk_core_round_rate_nolock() to its caller clk: Change clk_core_init_rate_req prototype clk: Set req_rate on reparenting clk: Take into account uncached clocks in clk_set_rate_range() ...
