mips: Replace ASSEMBLY with ASSEMBLER in the mips headers

2025-08-29T20:34:29+00:00

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembler code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. Defining such a macro was necessary in the early days of the kernel, since GCC only started providing __ASSEMBLER__ since version 3.0 in 2000 (see https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=f8f769ea4e69 ). However, having two macros can be very confusing nowadays for the developers when switching between userspace and kernelspace coding, or when dealing with uapi headers that should use __ASSEMBLER__ instead. So let's now standardize on the __ASSEMBLER__ macro that is provided by the compilers. This is almost a completely mechanical patch (done with a simple "sed -i" statement), with just one comment tweaked manually in arch/mips/include/asm/cpu.h (that was missing some underscores).

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 ...

The SOC_BRCMSTB is better depending on ARCH_BRCMSTB as it's defined for both arm and aarch64 but is more specific to the actual SoC's dependencies, it'll still get compile tested.

The Kconfig options belongs closer to the corresponding implementations, hence let's move them from the soc subsystem to the pmdomain subsystem. Cc: Florian Fainelli Cc: Ray Jui Cc: Scott Branden Cc: Cc: Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Ulf Hansson

soc: bcm: Move power-domain drivers to the genpd dir

2023-07-11T13:30:09+00:00

To simplify with maintenance let's move the bcm power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. While moving the drivers, we end up with a directory for bcm63xx that only contains a Kconfig file, which seems a bit silly. Let's therefore also move the Kconfig options into the Kconfig file a directory above, as it allows us to drop the directory too.

2023-03-14T21:07:17+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.
