Pull SoC driver updates from Arnd Bergmann: "The highlights for the driver support this time are - Qualcomm platforms gain support for the Qualcomm Secure Execution Environment firmware interface to access EFI variables on certain devices, and new features for multiple platform and firmware drivers. - Arm FF-A firmware support gains support for v1.1 specification features, in particular notification and memory transaction descriptor changes. - SCMI firmware support now support v3.2 features for clock and DVFS configuration and a new transport for Qualcomm platforms. - Minor cleanups and bugfixes are added to pretty much all the active platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and more. In particular, this contains portions of the treewide conversion to use __counted_by annotations and the device_get_match_data helper" * tag 'soc-drivers-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (156 commits) soc: qcom: pmic_glink_altmode: Print return value on error firmware: qcom: scm: remove unneeded 'extern' specifiers firmware: qcom: scm: add a missing forward declaration for struct device firmware: qcom: move Qualcomm code into its own directory soc: samsung: exynos-chipid: Convert to platform remove callback returning void soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size() soc: qcom: pmic_glink: fix connector type to be DisplayPort soc: ti: k3-socinfo: Avoid overriding return value soc: ti: k3-socinfo: Fix typo in bitfield documentation soc: ti: knav_qmss_queue: Use device_get_match_data() firmware: ti_sci: Use device_get_match_data() firmware: qcom: qseecom: add missing include guards soc/pxa: ssp: Convert to platform remove callback returning void soc/mediatek: mtk-mmsys: Convert to platform remove callback returning void soc/mediatek: mtk-devapc: Convert to platform remove callback returning void soc/loongson: loongson2_guts: Convert to platform remove callback returning void soc/litex: litex_soc_ctrl: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-qmgr: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-npe: Convert to platform remove callback returning void soc/hisilicon: kunpeng_hccs: Convert to platform remove callback returning void ...

soc/tegra: pmc: Drop the ->opp_to_performance_state() callback

2023-10-13T11:58:36Z

Since commit 7c41cdcd3bbe ("OPP: Simplify the over-designed pstate <-> level dance"), there is no longer any need for genpd providers to assign the ->opp_to_performance_state(), hence let's drop it.

soc/tegra: cbb: tegra194-cbb: Convert to platform remove callback returning void

2023-10-11T21:04:39Z

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(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pmdomain: tegra: Move Kconfig option to the pmdomain subsystem

2023-10-04T21:41:56Z

The Kconfig option belongs closer to the corresponding implementation, hence let's move it from the soc subsystem to the pmdomain subsystem. Cc: Thierry Reding Cc: Jonathan Hunter Cc: Mikko Perttunen Cc: Signed-off-by: Ulf Hansson

soc/tegra: cbb: Remove unnecessary print function dev_err()

2023-07-27T16:46:37Z

The print function dev_err() is redundant because platform_get_irq() already prints an error. ./drivers/soc/tegra/cbb/tegra-cbb.c:130:3-10: line 130 is redundant because platform_get_irq() already prints an error. ./drivers/soc/tegra/cbb/tegra-cbb.c:140:2-9: line 140 is redundant because platform_get_irq() already prints an error.

The includes were slightly out of order, so sort them correctly. Signed-off-by: Thierry Reding

soc/tegra: fuse: Use devm_platform_get_and_ioremap_resource()

2023-07-21T15:26:03Z

Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. Signed-off-by: Yangtao Li Signed-off-by: Thierry Reding

soc/tegra: Explicitly include correct DT includes

2023-07-21T15:12:19Z

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.

soc: tegra: Move powergate-bpmp driver to the genpd dir

2023-07-14T08:40:56Z

To simplify with maintenance let's move the powergate-bpmp driver to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. Note that, we leave the pmc driver in the soc directory for now, as it looks like it may need some re-structuring before it's ready to be moved.
