The newly added driver causes a Kconfig warning: WARNING: unmet direct dependencies detected for RTC_CLASS Depends on [n]: !S390 [=y] Selected by [m]: - TURRIS_OMNIA_MCU [=m] && CZNIC_PLATFORMS [=y] && (MACH_ARMADA_38X || COMPILE_TEST [=y]) && I2C [=m] && OF [=y] && WATCHDOG [=y] The problem here is that it selects entire subsystems, which normal device drivers should not do. Changes all of these to 'depends on' instead.

Not all registers in PMU_ALIVE block support atomic set/clear operations. GS101_SYSIP_DAT0 and GS101_SYSTEM_CONFIGURATION registers are two regs where attempting atomic access fails. As documentation on exactly which registers support atomic operations is not forthcoming. We default to atomic access, unless the register is explicitly added to the tensor_is_atomic() function. Update the comment to reflect this as well. Reviewed-by:

Merge tag 'qcom-drivers-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.11 Support for Shared Memory (shm) Bridge is added, which provides a stricter interface for handling of buffers passed to TrustZone. The X1Elite platform is added to uefisecapp allow list, to instantiate the efivars implementation. A new in-kernel implementation of the pd-mapper (or servreg) service is introduced, to replace the userspace dependency for USB Type-C and battery management. Support for sharing interrupts across multiple bwmon instances is added, and a refcount imbalance issue is corrected. The LLCC support for recent platforms is corrected, and SA8775P support is added. A new interface is added to SMEM, to expose "feature codes". One example of the usecase for this is to indicate to the GPU driver which frequencies are available on the given device. The interrupt consumer and provider side of SMP2P is updated to provide more useful names in interrupt stats. Support for using the mailbox binding and driver for outgoing IPC interrupt in the SMSM driver is introduced. socinfo driver learns about SDM670 and IPQ5321, as well as get some updates to the X1E PMICs. pmic_glink is bumped to now support managing 3 USB Type-C ports. * tag 'qcom-drivers-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (48 commits) soc: qcom: smp2p: Use devname for interrupt descriptions soc: qcom: smsm: Add missing mailbox dependency to Kconfig soc: qcom: add missing pd-mapper dependencies soc: qcom: icc-bwmon: Allow for interrupts to be shared across instances dt-bindings: interconnect: qcom,msm8998-bwmon: Add X1E80100 BWMON instances dt-bindings: interconnect: qcom,msm8998-bwmon: Remove opp-table from the required list firmware: qcom: tzmem: export devm_qcom_tzmem_pool_new() soc: qcom: add pd-mapper implementation soc: qcom: pdr: extract PDR message marshalling data soc: qcom: pdr: fix parsing of domains lists soc: qcom: pdr: protect locator_addr with the main mutex firmware: qcom: scm: clarify the comment in qcom_scm_pas_init_image() firmware: qcom: scm: add support for SHM bridge memory carveout firmware: qcom: tzmem: enable SHM Bridge support firmware: qcom: scm: add support for SHM bridge operations firmware: qcom: qseecom: convert to using the TZ allocator firmware: qcom: scm: make qcom_scm_qseecom_app_get_id() use the TZ allocator firmware: qcom: scm: make qcom_scm_lmh_dcvsh() use the TZ allocator firmware: qcom: scm: make qcom_scm_ice_set_key() use the TZ allocator firmware: qcom: scm: make qcom_scm_assign_mem() use the TZ allocator ...

When using /proc/interrupts to collect statistics on smp2p interrupt counts, it is hard to distinguish the different instances of smp2p from each other. For example to debug a processor boot issue, the ready and handover interrupts are checked for sanity to ensure the firmware reached a specific initialization stage. Remove "smp2p" string from the irq request so that the irq will default to the device name. Add an .irq_print_chip() callback to print the irq chip name as the device name. These two changes allow for a unique name to be used in /proc/interrupts as shown below. / # cat /proc/interrupts | grep smp2p 18: ... ipcc 196610 Edge smp2p-adsp 20: ... ipcc 131074 Edge smp2p-modem 170: ... smp2p-modem 1 Edge q6v5 ready 178: ... smp2p-adsp 1 Edge q6v5 ready Signed-off-by:
