Add support for new field coming with socinfo structure under v17 to get hardware platform's oem variant id. This is to enable OEMs to have minor changes in the board, but to use the same platform subtype as the one supported by Qualcomm. The new field is to be used in platform overlay file. Default value is 0, reserved for Qualcomm platforms. Also, add debugfs support to read this field for a device. Signed-off-by:

This driver relies on SMEM to populate items for each subsystem before the device probes. The items in SMEM that are being looked for are populated by the subsystems lazily, and therefore may not exist until the device has booted. For example, if I build this driver into the kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file populated, because the modem boots and populates the SMEM item after this driver probes. Always populate the files for the subsystems if they're in SMEM, and make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM items still isn't there. This way we can run a simple command like grep ^ /sys/kernel/debug/qcom_stats/* and collect the subsystem sleep stats without interspersed errors or missing details entirely because this driver probed first.

With the PMIC GLINK service, the host OS subscribes to USB-C altmode messages, which are sent by the firmware to notify the host OS about state updates and HPD interrupts. The pmic_glink_altmode driver registers for these notifications and propagates the notifications as typec_mux, typec_switch and DRM OOB notifications as necessary to implement DisplayPort altmode support.

The PMIC GLINK service runs on one of the co-processors of some modern Qualcomm platforms and implements USB-C and battery managements. It uses a message based protocol over GLINK for communication with the OS, hence the name. The driver implemented provides the rpmsg device for communication and uses auxiliary bus to spawn off individual devices in respective subsystem. The auxiliary devices are spawned off from a platform_device, so that the drm_bridge is available early, to allow the DisplayPort driver to probe even before the remoteproc has spun up.

When the firmware (FW) supports multiple requests per VM, multiple requests from the same/different VM can reach the firmware at the same time. Since the firmware currently being used has limited resources, it guards them with a resource lock and puts requests on a wait-queue internally and signals to HLOS that it is doing so. It does this by returning a new return value in addition to success or error: SCM_WAITQ_SLEEP. A sleeping SCM call can be woken up by an interrupt that the FW raises. 1) SCM_WAITQ_SLEEP: When an SCM call receives this return value instead of success or error, FW has placed this call on a wait-queue and has signalled HLOS to put it to non-interruptible sleep. Along with this return value, FW also passes to HLOS `wq_ctx` - a unique number (UID) identifying the wait-queue that it has put the call on, internally. This is to help HLOS with its own bookkeeping to wake this sleeping call later. Additionally, FW also passes to HLOS `smc_call_ctx` - a UID identifying the SCM call thus being put to sleep. This is also for HLOS' bookkeeping to wake this call up later. These two additional values are passed via the a1 and a2 registers. N.B.: The "ctx" in the above UID names = "context". The handshake mechanism that HLOS uses to talk to FW about wait-queue operations involves two new SMC calls. 1) get_wq_ctx(): Arguments: None Returns: wq_ctx, flags, more_pending Get the wait-queue context, and wake up either one or all of the sleeping SCM calls associated with that wait-queue. Additionally, repeat this if there are more wait-queues that are ready to have their requests woken up (`more_pending`). 2) wq_resume(smc_call_ctx): Arguments: smc_call_ctx HLOS needs to issue this in response to receiving an IRQ, passing to FW the same smc_call_ctx that FW receives from HLOS via the get_wq_ctx() call. (The mechanism to wake a SMC call back up is described in detail below) VM_1 VM_2 Firmware │ │ │ │ │ │ │ │ │ │ │ │ │ REQUEST_1 │ │ ├────────────────────────┼─────────────────────────────────┤ │ │ │ │ │ ┌──┼──┐ │ │ │ │ │ │ │ REQUEST_2 │ │ │ │ ├──────────────────────────────┼──┤ │ │ │ │ │ │Resource │ │ │ │ │is busy │ │ {WQ_SLEEP} │ │ │ │ │◄─────────────────────────────┼──┤ │ │ │ wq_ctx, smc_call_ctx │ │ │ │ │ └──┼──┘ │ REQUEST_1 COMPLETE │ │ │◄───────────────────────┼─────────────────────────────────┤ │ │ │ │ │ IRQ │ │ │◄─-------------------------------│ │ │ │ │ │ get_wq_ctx() │ │ ├────────────────────────────────►│ │ │ │ │ │ │ │ │◄────────────────────────────────┤ │ │ wq_ctx, flags, and │ │ │ more_pending │ │ │ │ │ │ │ │ │ wq_resume(smc_call_ctx) │ │ ├────────────────────────────────►│ │ │ │ │ │ │ │ │ REQUEST_2 COMPLETE │ │ │◄────────────────────────────────┤ │ │ │ │ │ │ With the exception of get_wq_ctx(), the other SMC call wq_resume() can return WQ_SLEEP (these nested rounds of WQ_SLEEP are not shown in the above diagram for the sake of simplicity).

Request Completion in the above diagram refers to either a success return value (zero) or error (and not SMC_WAITQ_SLEEP) Also add the interrupt handler that wakes up a sleeping SCM call.

Sync the SoC IDs in qcom,ids.h with relevant entries from Qualcomm's LK bootloader [1] that is used for almost all older Qualcomm SoCs. Several of these are already supported, e.g.: - MSM8960 -> APQ8060, MSM8260, ... - MSM8976 -> APQ8076 - MSM8956 -> APQ8056 Others are currently being worked on, e.g.: - MSM8909(W) -> APQ8009(W), MSM8905, MSM8209, ... - MSM8939 -> MSM8239, ... And even all remaining ones added are close enough to what is already supported so that future support is realistic (if someone steps up to do the work). Add all of them at once to avoid having to add them one by one in the future. This will also benefit other projects making use of the same dt-bindings, e.g. bootloaders where adding support for all these SoCs is a bit easier than on Linux.

The SCM VMIDs represent predefined mappings that come from the irreplaceable and non-omittable firmware that comes with every Qualcomm SoC (unless you steal engineering samples from the factory) and help clarify otherwise totally magic numbers which we are required to pass to the secure world for some parts of the SoC to work at all (with modem being the prime example). On top of that, with changes to the rmtfs binding, secure VMIDs will become useful to have in device trees for readability. Separate them out and add to include/dt-bindings. Signed-off-by:
