2023-08-23nvmem: sec-qfprom: Add Qualcomm secure QFPROM supportKomal Bajaj3-0/+111
For some of the Qualcomm SoC's, it is possible that some of the fuse regions or entire qfprom region is protected from non-secure access. In such situations, the OS will have to use secure calls to read the region. With that motivation, add secure qfprom driver.

2023-08-23nvmem: Explicitly include correct DT includesRob Herring16-16/+9
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Add SFP (Security Fuse Processor) read support for NXP (Freescale) QorIQ series SOC's. This patch adds support for the T1023 SOC using the SFP offset from the existing T1023 device tree.

2023-08-23dt-bindings: nvmem: fixed-cell: add compatible for MAC cellsRafał Miłecki3-1/+42
A lot of home routers have NVMEM fixed cells containing MAC address that need some further processing. In ~99% cases MAC needs to be: 1. Optionally parsed from ASCII format 2. Increased by a vendor-picked value There was already an attempt to design a binding for that at NVMEM device level in the past. It wasn't accepted though as it didn't really fit NVMEM device layer. The introduction of NVMEM fixed-cells layout seems to be an opportunity to provide a relevant binding in a clean way. This commit adds a *generic* compatible string: "mac-base". As always it needs to be carefully reviewed. OpenWrt project currently supports ~300 home routers that have NVMEM cell with binary-stored base MAC.T hose devices are manufactured by multiple vendors. There are TP-Link devices (76 of them), Netgear (19), D-Link (11), OpenMesh (9), EnGenius (8), GL.iNet (8), ZTE (7), Xiaomi (5), Ubiquiti (6) and more. Those devices don't share an architecture or SoC. Another 200 devices have base MAC stored in an ASCII format (not all those devices have been converted to DT though). It would be impractical to provide unique "compatible" strings for NVMEM layouts of all those devices. It seems like a valid case for allowing a generic binding instead. Even if this binding will not be sufficient for some further devices it seems to be useful enough as it is.

2023-08-22misc: fastrpc: Pass proper scm arguments for static process initEkansh Gupta1-4/+9
Memory is allocated for dynamic loading when audio daemon is trying to attach to audioPD on DSP side. This memory is allocated from reserved CMA memory region and needs ownership assignment to new VMID in order to use it from audioPD. In the current implementation, arguments are not correctly passed to the scm call which might result in failure of dynamic loading on audioPD. Added changes to pass correct arguments during daemon attach request.

2023-08-22misc: fastrpc: Fix incorrect DMA mapping unmap requestEkansh Gupta1-3/+5
Scatterlist table is obtained during map create request and the same table is used for DMA mapping unmap. In case there is any failure while getting the sg_table, ERR_PTR is returned instead of sg_table. When the map is getting freed, there is only a non-NULL check of sg_table which will also be true in case failure was returned instead of sg_table. This would result in improper unmap request. Add proper check before setting map table to avoid bad unmap request.

Remote heap is used by DSP audioPD on need basis. This memory is allocated from reserved CMA memory region and is then shared with audioPD to use it for it's functionality. Current implementation of remote heap is not allocating the memory from CMA region, instead it is allocating the memory from SMMU context bank. The arguments passed to scm call for the reassignment of ownership is also not correct. Added changes to allocate CMA memory and have a proper ownership reassignment.

Coresight TRBE driver shares a single platform data (which is empty btw). However, with the commit 4e8fe7e5c3a5 ("coresight: Store pointers to connections rather than an array of them") the coresight core would free up the pdata, resulting in multiple attempts to free the same pdata for TRBE instances. Fix this by allocating a pdata per coresight_device.

According to the gcc manual functions "whose return value is not affected by changes to the observable state of the program and that have no observable effects on such state other than to return a value may lend themselves to optimizations such as common subexpression elimination. Declaring such functions with the 'const' attribute allows GCC to avoid emitting some calls in repeated invocations of the function with the same argument values." counter_priv() is such a function and so can be marked with the const function attribute.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-08-13platform/x86: lenovo-ymc: Only bind on machines with a convertible DMI ↵Hans de Goede1-0/+25
chassis-type The lenovo-ymc driver is causing the keyboard + touchpad to stop working on some regular laptop models such as the Lenovo ThinkBook 13s G2 ITL 20V9. The problem is that there are YMC WMI GUID methods in the ACPI tables of these laptops, despite them not being Yogas and lenovo-ymc loading causes libinput to see a SW_TABLET_MODE switch with state 1. This in turn causes libinput to ignore events from the builtin keyboard and touchpad, since it filters those out for a Yoga in tablet mode. Similar issues with false-positive SW_TABLET_MODE=1 reporting have been seen with the intel-hid driver. Copy the intel-hid driver approach to fix this and only bind to the WMI device on machines where the DMI chassis-type indicates the machine is a convertible. Add a 'force' module parameter to allow overriding the chassis-type check so that users can easily test if the YMC interface works on models which report an unexpected chassis-type.
