https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.5 Konrad Dybcio is promoted, from reviewer, to co-maintainer. The mdt_loader gets a fix to the detection of split binaries, where the previous logic sometimes concluded that the first segments was not split, in a split image. The unconditional calling of scm_pas_mem_setup() turns out to cause a regression and is reverted. The altmode subfunction of pmic_glink is enabled for SM8450. A new driver for exposing power statistics from the RPM, for debugging purposes, is introduced. OCMEM gets a debug prints of the hardware version, QMI helpers are transitioned to alloc_ordered_workqueue() and an error message in ramp_controller is improved. An API is introduced to the SMEM driver to allow other drivers to query the SoC id, rather than open-coding the parsing of the relevant SMEM item. This is then used to clean up the Qualcomm NVMEM-based cpufreq driver. Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302. * tag 'qcom-drivers-for-6.5' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (23 commits) soc: qcom: ocmem: Add OCMEM hardware version print cpufreq: qcom-nvmem: use helper to get SMEM SoC ID cpufreq: qcom-nvmem: use SoC ID-s from bindings soc: qcom: smem: introduce qcom_smem_get_soc_id() soc: qcom: smem: Switch to EXPORT_SYMBOL_GPL() soc: qcom: socinfo: move SMEM item struct and defines to a header soc: qcom: mdt_loader: Fix unconditional call to scm_pas_mem_setup MAINTAINERS: Add Konrad Dybcio as linux-arm-msm co-maintainer dt-bindings: sram: qcom,imem: Document MSM8226 soc: qcom: socinfo: Add Soc ID for IPQ5312 and IPQ5302 dt-bindings: arm: qcom,ids: add SoC ID for IPQ5312 and IPQ5302 soc: qcom: socinfo: Add IDs for IPQ5018 family dt-bindings: arm: qcom,ids: Add IDs for IPQ5018 family soc: qcom: Introduce RPM master stats driver dt-bindings: soc: qcom: Add RPM Master stats soc: qcom: qmi: Use alloc_ordered_workqueue() to create ordered workqueues soc: qcom: ramp_controller: Improve error message for failure in .remove() dt-bindings: soc: qcom: smd-rpm: allow MSM8226 over SMD soc: qcom: rpmpd: use correct __le32 type dt-bindings: soc: qcom: eud: Fix compatible string in the example ...

secondary sequencer The select_fifo/dma_mode() functions in geni driver enable/disable interrupts (secondary included) conditionally for non-uart modes, while uart is supposed to manage this internally. However, only uart uses secondary IRQs while spi, i2c do not care about these at all making their enablement (or disablement) totally unnecessary for these protos. Similarly, select_gpi_mode() also does disable s_irq and its useless again. Drop enabling/disabling secondary IRQs. This doesn't solve any observed problem but only gets rid of code pieces that are not required.

The enhanced detection introduced in commit '210d12c8197a ("soc: qcom: mdt_loader: Enhance split binary detection")' requires that all segments lies within the file on disk. But the Qualcomm firmware files consistently has a BSS-like segment at the end, with a p_offset aligned to the next 4k boundary. As the p_size is 0 and there's nothing to load, the image is not padded to cover this (empty) segment. Ignore zero-sized segments when determining if the image is split, to avoid this problem.

2023-06-09soc/tegra: pmc: Simplify debugfs initializationThierry Reding1-22/+4
debugfs calls should generally not be error-checked to simplify the case where debugfs is disabled. Since this driver is built-in and has the sysfs bind/unbind attributes disabled, it cannot be unloaded, so there is no need to hold onto a reference to the debugfs files that are created. We can further simplify this by moving the debugfs file creation to a later stage to avoid any cleanup we might have to do during error unwind operations. This is also a little cleaner because the debugfs file relies on data structures that are created at a later point than when the file was previously created.

2023-06-05soc: renesas: rmobile-sysc: Convert to readl_poll_timeout_atomic()Geert Uytterhoeven1-20/+9
Use readl_poll_timeout_atomic() instead of open-coding the same operation. 1. rmobile_pd_power_down(): as typically less than 20 retries are needed, PSTR_RETRIES (100) µs is a suitable timeout value. 2. __rmobile_pd_power_up(): the old method of first polling some cycles with a 1 µs delay, followed by more polling cycles without any delay didn't make much sense, as the latter was insignificant compared to the former. Furthermore, typically no retries are needed. Hence just retain the polling with delay.

iopoll: Busy loop and timeout improvements
2023-06-05iopoll: Do not use timekeeping in read_poll_timeout_atomic()Geert Uytterhoeven1-5/+17
read_poll_timeout_atomic() uses ktime_get() to implement the timeout feature, just like its non-atomic counterpart. However, there are several issues with this, due to its use in atomic contexts: 1. When called in the s2ram path (as typically done by clock or PM domain drivers), timekeeping may be suspended, triggering the WARN_ON(timekeeping_suspended) in ktime_get(): WARNING: CPU: 0 PID: 654 at kernel/time/timekeeping.c:843 ktime_get+0x28/0x78 Calling ktime_get_mono_fast_ns() instead of ktime_get() would get rid of that warning. However, that would break timeout handling, as (at least on systems with an ARM architectured timer), the time returned by ktime_get_mono_fast_ns() does not advance while timekeeping is suspended. Interestingly, (on the same ARM systems) the time returned by ktime_get() does advance while timekeeping is suspended, despite the warning. 2. Depending on the actual clock source, and especially before a high-resolution clocksource (e.g. the ARM architectured timer) becomes available, time may not advance in atomic contexts, thus breaking timeout handling. Fix this by abandoning the idea that one can rely on timekeeping to implement timeout handling in all atomic contexts, and switch from a global time-based to a locally-estimated timeout handling. In most (all?) cases the timeout condition is exceptional and an error condition, hence any additional delays due to underestimating wall clock time are irrelevant.

2023-06-05iopoll: Call cpu_relax() in busy loopsGeert Uytterhoeven1-0/+2
It is considered good practice to call cpu_relax() in busy loops, see Documentation/process/volatile-considered-harmful.rst. This can not only lower CPU power consumption or yield to a hyperthreaded twin processor, but also allows an architecture to mitigate hardware issues (e.g. ARM Erratum 754327 for Cortex-A9 prior to r2p0) in the architecture-specific cpu_relax() implementation. In addition, cpu_relax() is also a compiler barrier. It is not immediately obvious that the @op argument "function" will result in an actual function call (e.g. in case of inlining). Where a function call is a C sequence point, this is lost on inlining. Therefore, with agressive enough optimization it might be possible for the compiler to hoist the: (val) = op(args); "load" out of the loop because it doesn't see the value changing. The addition of cpu_relax() would inhibit this. As the iopoll helpers lack calls to cpu_relax(), people are sometimes reluctant to use them, and may fall back to open-coded polling loops (including cpu_relax() calls) instead. Fix this by adding calls to cpu_relax() to the iopoll helpers: - For the non-atomic case, it is sufficient to call cpu_relax() in case of a zero sleep-between-reads value, as a call to usleep_range() is a safe barrier otherwise. However, it doesn't hurt to add the call regardless, for simplicity, and for similarity with the atomic case below. - For the atomic case, cpu_relax() must be called regardless of the sleep-between-reads value, as there is no guarantee all architecture-specific implementations of udelay() handle this.
