Qualcomm driver updates for v5.20 This introduces a new driver that requests interconnect bandwidth based on throughput measurements of the bwmon hardware blocks found associated with, among other things, the CPU subsystem on many Qualcomm platforms. It introduces support for the SCM wrapper driver to vote for interconnect bandwidth for operations that needs bandwidth to the crypto engine. This ensures both performance and guards against issues caused by lacking votes for this path. The socinfo driver gains knowledge about the SC7180P SoC. It contains a range of fixes for spelling mistakes, refcount leaks in various drivers and removes some redundant code from the apr remove path. The SCM DT bindings are updated to declare support for QCS404, SM6125 and SDX65. The command db driver has a strncpy() converted to strscpy_pad() and then back again with proper documentation to why this was the right API. * tag 'qcom-drivers-for-5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: icc-bwmon: Add bandwidth monitoring driver dt-bindings: interconnect: qcom,msm8998-cpu-bwmon: add BWMON device soc/qcom: Make QCOM_RPMPD select PM_GENERIC_DOMAINS/_OF soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register soc: qcom: llcc: Fix syntax errors in comments soc: qcom: ocmem: Fix refcount leak in of_get_ocmem dt-bindings: soc: qcom,wcnss: remove unneeded ref for names firmware: qcom_scm: Add bw voting support to the SCM interface dt-bindings: firmware: qcom-scm: Add interconnects property soc: qcom: cmd-db: replace strscpy_pad() with strncpy() dt-bindings: firmware: scm: Add compatible for SDX65 dt-bindings: arm: qcom: switch maintainer to Bjorn soc: qcom: rpmhpd: fix typos in comment soc: qcom: correct kerneldoc soc: qcom: cmd-db: replace strncpy() with strscpy_pad() firmware: qcom_scm-legacy: correct kerneldoc dt-bindings: firmware: document Qualcomm QCS404 and SM6125 SCM soc: qcom: apr: Drop redundant check in .remove() firmware: qcom_scm: drop unexpected word "the" soc: qcom: socinfo: Add an ID for sc7180P Link: https://lore.kernel.org/r/20220712021830.1271398-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

[Description] Exit SubVP if MPO is in use since SubVP + MPO together is not supported. - Don't add SubVP at validation time if we see MPO is in use Issues fixed in the SubVP / MPO transition: 1. Enable phantom pipes in post unlock function to prevent underflow when an active pipe is being transitioned to be a phantom pipe (VTG updates take place right away). Also must wait for VUPDATE of the main pipe to complete first 2. Don't wait for MPCC idle when transitioning a phantom pipe to an actual pipe. MPCC_STATUS is never asserted due to OTG being off for phantom pipes 3. When transitioning an active pipe to phantom, program DET right away (same as disabling the pipe) or the DET update will only take when the phantom pipe is enabled which can cause DET allocation errors. 4. For K1/K2 programming of phantom pipes, use same settings as the main pipe. Also don't program K1 / K2 = 0xF ever since the field is only 1 / 2 bits wide.

2022-07-12ice: change devlink code to read NVM in blocksPaul M Stillwell Jr1-19/+40
When creating a snapshot of the NVM the driver needs to read the entire contents from the NVM and store it. The NVM reads are protected by a lock that is shared between the driver and the firmware. If the driver takes too long to read the entire NVM (which can happen on some systems) then the firmware could reclaim the lock and cause subsequent reads from the driver to fail. We could fix this by increasing the timeout that we pass to the firmware, but we could end up in the same situation again if the system is slow. Instead have the driver break the reading of the NVM into blocks that are small enough that we have confidence that the read will complete within the timeout time, but large enough not to cause significant AQ overhead.

2022-07-12PCI: endpoint: Enable DMA tests for endpoints with DMA capabilitiesFrank Li1-10/+106
Some PCI Endpoint controllers integrate an eDMA (embedded DMA). eDMA can bypass the outbound memory address translation unit to access all RC memory space. Add eDMA support for pci-epf-test. Depending on HW availability, the EPF test can use either eDMA or general system DMA controllers to perform DMA. The test tries to use eDMA first and falls back to general system DMA controllers if there's no eDMA Separate dma_chan to dma_chan_tx and dma_chan_rx. Search for an eDMA channel first, then search for a memory-to-memory DMA channel. If general memory to memory channels are used, dma_chan_rx = dma_chan_tx. Add dma_addr_t dma_remote in pci_epf_test_data_transfer() because eDMA uses remote RC physical address directly. Add enum dma_transfer_direction dir in pci_epf_test_data_transfer() because eDMA chooses the correct RX/TX channel by dir. The overall steps are: 1. Execute dma_request_channel() and filter function to find correct eDMA RX and TX Channel. If a channel does not exist, fallback to try to allocate general memory to memory DMA channel. 2. Execute dmaengine_slave_config() to configure remote side physical address. 3. Execute dmaengine_prep_slave_single() to create transfer descriptor. 4. Execute tx_submit(). 5.

pcie_aspm_pm_state_change() was introduced at the inception of PCIe ASPM code, but it can cause some issues. For instance, when ASPM config is changed via sysfs, those changes won't persist across power state change because pcie_aspm_pm_state_change() overwrites them. Also, if the driver restores L1SS [1] after system resume, the restored state will also be overwritten by pcie_aspm_pm_state_change(). Remove pcie_aspm_pm_state_change(). If there's any hardware that really needs it to function, a quirk can be used instead.

2022-07-12PM / devfreq: tegra30: Register config_clks helperViresh Kumar1-3/+19
There is a corner case with Tegra30, where we want to skip clk configuration that happens via dev_pm_opp_set_opp(), but still want the OPP core to read the "opp-hz" property so we can find the right OPP via freq finding helpers. The OPP core provides support for the platforms to provide config_clks helpers now, lets use that instead of devm_pm_opp_of_add_table_noclk() to achieve the same result, as the OPP core won't parse the DT's "opp-hz" property anymore if the clock isn't provided.

2022-07-12OPP: Allow multiple clocks for a deviceViresh Kumar4-82/+240
This patch adds support to allow multiple clocks for a device. The design is pretty much similar to how this is done for regulators, and platforms can supply their own version of the config_clks() callback if they have multiple clocks for their device. The core manages the calls via opp_table->config_clks() eventually. We have kept both "clk" and "clks" fields in the OPP table structure and the reason is provided as a comment in _opp_set_clknames(). The same isn't done for "rates" though and we use rates[0] at most of the places now.

If we reset because of an error, we need to preserve values for the clock frequency. Otherwise, glitches may be seen on the bus.
