The current probe/remove functions are implemented separately for each target, but they are almost identical. Replace them with common functions that can be used across all rpmh targets.

Merge tag 'qcom-arm64-for-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/dt

2020-12-08T22:50:08+00:00

Qualcomm ARM64 DT updates for 5.11 For SM8250 the recently introduced support for handling boot-loader stream mappings in the ARM SMMU allow us to enable this, and thereby USB controller and PHY, SDHCI controller and FastRPC, as well as support for the SM8250 HDK board has been added. Additionally PRNG and RTC is enabled. Similarly for SM8150, the ARM SMMU could be added which allows the secondary USB controller and PHYs, as well as WiFi to be added and support for the SM8150 HDK board to be introduced. Additionally Coresight and support for the last-level cache controller was added. MSM8916 finally has VDDCX and VDDMX removed as regulators and are now handled by the rpmpd driver for the devices controlling them. The Longsheer L8150 gains touchscreen, sensors, vibrator and LED support. MSM8992 gains USB and SDHCI support as well as an I2C controller and the associated RMI4 based touchscreen for the Lumia 950. MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm support. Then support for the Lumia 950 XL is added. SDM845 gains interconnect properties for a number of devices and the GENI wrappers gains iommu stream configuration, which means DMA operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the SMMU enabled, a few fixes and the description of the eDP bridge and panel means that the laptop can now boot mainline with working display, GPU, WiFi and audio. SC7180 gains a slew of smaller improvements and fixes. * tag 'qcom-arm64-for-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (93 commits) arm64: dts: qcom: c630: Define eDP bridge and panel arm64: dts: qcom: c630: Fix pinctrl pins properties arm64: dts: qcom: c630: Polish i2c-hid devices arm64: dts: qcom: sc7180: Add lpass cpu node for I2S driver arm64: dts: sdm845: Add interconnect properties for QUP interconnect: qcom: sdm845: Add the missing nodes for QUP dt-bindings: interconnect: sdm845: Add IDs for the QUP ports arm64: dts: qcom: c630: Expose LID events arm64: dts: qcom: c630: Re-enable apps_smmu dts: qcom: sdm845: Add dt entries to support crypto engine. arm64: dts: qcom: qrb5165-rb5: Add support for MCP2518FD arm64: dts: qcom: sdm845: use GIC_SPI for IPA interrupts arm64: dts: qcom: sc7180: use GIC_SPI for IPA interrupts arm64: dts: qcom: sc7180: limit IPA iommu streams arm64: dts: qcom: sm8150: Add Coresight support arm64: dts: qcom: sc7180-trogdor: Make pp3300_a the default supply for pp3300_hub arm64: dts: qcom: sc7180: Add DDR/L3 votes for the pro variant arm64: dts: qcom: sc7180-lite: Tweak DDR/L3 scaling on SC7180-lite arm64: dts: qcom: sc7180-trogdor: add "pen-insert" label for trogdor arm64: qcom: sc7180: trogdor: Add ADC nodes and thermal zone for charger thermistor ...

interconnect: qcom: sdm845: Add the missing nodes for QUP

2020-11-30T16:42:47+00:00

The QUP nodes are currently defined just as entries in the topology, but they are not referenced by any of the NoCs. Let's fix this and "attach" them to their NoCs, so that the QUP drivers are able to use them as path endpoints and scale their bandwidth. This is based on the information from the downstream msm-4.9 kernel.

interconnect: qcom: sdm845: Init BCMs before creating the nodes

2020-10-15T06:24:00+00:00

Currently if we use sync_state, by default the bandwidth is maxed out, but in order to set this in hardware, the BCMs (Bus Clock Managers) need to be initialized first. Move the BCM initialization before creating the nodes to fix this.

interconnect: qcom: sdm845: Enable keepalive for the MM1 BCM

2020-10-15T06:23:25+00:00

After enabling interconnect scaling for display on the db845c board, in certain configurations the board hangs, while the following errors are observed on the console: Error sending AMC RPMH requests (-110) qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 qcom_rpmh TCS Busy, retrying RPMH message send: addr=0x50000 ... In this specific case, the above is related to one of the sequencers being stuck, while client drivers are returning from probe and trying to disable the currently unused clock and interconnect resources. Generally we want to keep the multimedia NoC enabled like the rest of the NoCs, so let's set the keepalive flag on it too.

interconnect: qcom: Use icc_sync_state

2020-09-18T05:57:18+00:00

Lowering the bandwidth on the bus might have negative consequences if it's done before all consumers had a chance to cast their vote. Now by default the framework sets the bandwidth to maximum during boot. We need to use the icc_sync_state callback to notify the framework when all consumers are probed and there is no need to keep the bandwidth set to maximum anymore.
