firmware: imx: Add stub functions for SCMI CPU API

2025-09-11T01:59:08Z

To ensure successful builds when CONFIG_IMX_SCMI_CPU_DRV is not enabled, this patch adds static inline stub implementations for the following functions: - scmi_imx_cpu_start() - scmi_imx_cpu_started() - scmi_imx_cpu_reset_vector_set() These stubs return -EOPNOTSUPP to indicate that the functionality is not supported in the current configuration. This avoids potential build or link errors in code that conditionally calls these functions based on feature availability.

firmware: imx: Add stub functions for SCMI MISC API

2025-09-11T01:59:07Z

To ensure successful builds when CONFIG_IMX_SCMI_MISC_DRV is not enabled, this patch adds static inline stub implementations for the following functions: - scmi_imx_misc_ctrl_get() - scmi_imx_misc_ctrl_set() These stubs return -EOPNOTSUPP to indicate that the functionality is not supported in the current configuration. This avoids potential build or link errors in code that conditionally calls these functions based on feature availability. This patch also drops the changes in commit 540c830212ed ("firmware: imx: remove duplicate scmi_imx_misc_ctrl_get()"). The original change aimed to simplify the handling of optional features by removing conditional stubs. However, the use of conditional stubs is necessary when CONFIG_IMX_SCMI_MISC_DRV is n, while consumer driver is set to y. This is not a matter of preserving legacy patterns, but rather to ensure that there is no link error whether for module or built-in.

Pull SoC driver updates from Arnd Bergmann: "Changes are all over the place, but very little sticks out as noteworthy. There is a new misc driver for the Raspberry Pi 5's RP1 multifunction I/O chip, along with hooking it up to the pinctrl and clk frameworks. The reset controller and memory subsystems have mainly small updates, but there are two new reset drivers for the K230 and VC1800B SoCs, and new memory driver support for Tegra264. The ARM SMCCC and SCMI firmware drivers gain a few more features that should help them be supported across more environments. Similarly, the SoC specific firmware on Tegra and Qualcomm get minor enhancements and chip support. In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an overhaul for code robustness, the Tegra and Qualcomm and NXP drivers grow to support more chips, while the Hisilicon, Mediatek and Renesas drivers see mostly janitorial fixes" * tag 'soc-drivers-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (100 commits) bus: del unnecessary init var soc: fsl: qe: convert set_multiple() to returning an integer pinctrl: rp1: use new GPIO line value setter callbacks soc: hisilicon: kunpeng_hccs: Fix incorrect log information dt-bindings: soc: qcom: qcom,pmic-glink: document Milos compatible dt-bindings: soc: qcom,aoss-qmp: document the Milos Always-On Subsystem side channel dt-bindings: firmware: qcom,scm: document Milos SCM Firmware Interface soc: qcom: socinfo: Add support to retrieve APPSBL build details soc: qcom: pmic_glink: fix OF node leak soc: qcom: spmi-pmic: add more PMIC SUBTYPE IDs soc: qcom: socinfo: Add PM7550 & PMIV0108 PMICs soc: qcom: socinfo: Add SoC IDs for SM7635 family dt-bindings: arm: qcom,ids: Add SoC IDs for SM7635 family firmware: qcom: scm: request the waitqueue irq *after* initializing SCM firmware: qcom: scm: initialize tzmem before marking SCM as available firmware: qcom: scm: take struct device as argument in SHM bridge enable firmware: qcom: scm: remove unused arguments from SHM bridge routines soc: qcom: rpmh-rsc: Add RSC version 4 support memory: tegra: Add Tegra264 MC and EMC support firmware: tegra: bpmp: Fix build failure for tegra264-only config ...

firmware: qcom: scm: take struct device as argument in SHM bridge enable

2025-07-17T03:50:55Z

qcom_scm_shm_bridge_enable() is used early in the SCM initialization routine. It makes an SCM call and so expects the internal __scm pointer in the SCM driver to be assigned. For this reason the tzmem memory pool is allocated *after* this pointer is assigned. However, this can lead to a crash if another consumer of the SCM API makes a call using the memory pool between the assignment of the __scm pointer and the initialization of the tzmem memory pool. As qcom_scm_shm_bridge_enable() is a special case, not meant to be called by ordinary users, pull it into the local SCM header. Make it take struct device as argument. This is the device that will be used to make the SCM call as opposed to the global __scm pointer. This will allow us to move the tzmem initialization *before* the __scm assignment in the core SCM driver.
