2025-05-16soc: Switch to irq_domain_create_*()Jiri Slaby (SUSE)
irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2025-03-06soc/tegra: pmc: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

2024-11-01soc: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

2024-02-16soc/tegra: pmc: Update scratch as an optional aperturePetlozu Pravareshwar
Scratch address space register is used to store reboot reason. For some Tegra234 systems, the scratch space is not available to store the reboot reason. This is because scratch region on these systems is not accessible by the kernel as restricted by the Hypervisor. Such systems would delist scratch aperture from PMC DT node. Hence this change makes scratch as optional aperture and also avoids registering reboot notifier if scratch address space isn't mapped.

Currently in PMC driver, we try to map these additional address ranges on all SoCs and if we fail then we assume that the range is not valid for an SoC.

Commit c5b2d43e67bb ("soc/tegra: fuse: Add ACPI support for Tegra194 and Tegra234") updated the Tegra fuse driver to add ACPI support and added a test to the tegra_fuse_readl() function to check if the device is booting with device-tree. This test passes 'fuse->dev' variable to dev_fwnode() but does not check first is 'fuse->dev' is valid. This is causing a crash to occur in Tegra XUSB PHY driver that calls the tegra_fuse_readl() function before 'fuse->dev' variable has been initialised ...

Add ACPI support for Tegra194 & Tegra243 SoC's. This requires following modifications to the probe when ACPI boot is used: - Initialize soc data. - Add nvmem lookups. - Register soc device. - use devm_clk_get_optional() instead of devm_clk_get() to get fuse->clk, as fuse clocks are not required when using ACPI boot. Also, drop '__init' keyword for tegra_soc_device_register() as this is also used by tegra_fuse_probe() and use dev_err_probe() wherever applicable.

2023-10-11soc/tegra: cbb: tegra194-cbb: Convert to platform remove callback returning voidUwe Kleine-König
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(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-07-21soc/tegra: Explicitly include correct DT includesRob Herring
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.
