interconnect: qcom: Convert to platform remove callback returning void

2023-10-18T10:37:39Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Several drivers use qcom_icc_rpmh_remove() as remove callback which returns zero unconditionally. Make it return void and use .remove_new in the drivers. There is no change in behaviour.

interconnect: Explicitly include correct DT includes

2023-07-16T15:27:27Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

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

2020-12-08T22:50:08Z

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 ...
