2023-04-05nvmem: core: support specifying both: cell raw data & post read lengthsRafał Miłecki
Callback .read_post_process() is designed to modify raw cell content before providing it to the consumer. So far we were dealing with modifications that didn't affect cell size (length). In some cases however cell content needs to be reformatted and resized. It's required e.g. to provide properly formatted MAC address in case it's stored in a non-binary format (e.g. using ASCII). There were few discussions how to optimally handle that. Following possible solutions were considered: 1. Allow .read_post_process() to realloc (resize) content buffer 2. Allow .read_post_process() to adjust (decrease) just buffer length 3. Register NVMEM cells using post-read sizes The preferred solution was the last one. The problem is that simply adjusting "bytes" in NVMEM providers would result in core code NOT passing whole raw data to .read_post_process() callbacks. It means callback functions couldn't do their job without somehow manually reading original cell content on their own. This patch deals with that by registering NVMEM cells with both lengths: raw content one and post read one. It allows: 1. Core code to read whole raw cell content 2. Callbacks to return content they want Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Link: https://lore.kernel.org/r/20230404172148.82422-35-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-04-05nvmem: mtk-efuse: Support postprocessing for GPU speed binning dataAngeloGioacchino Del Regno
On some MediaTek SoCs GPU speed binning data is available for read in the SoC's eFuse array but it has a format that is incompatible with what the OPP API expects, as we read a number from 0 to 7 but opp-supported-hw is expecting a bitmask to enable an OPP entry: being what we read limited to 0-7, it's straightforward to simply convert the value to BIT(value) as a post-processing action. So, introduce post-processing support and enable it by evaluating the newly introduced platform data's `uses_post_processing` member, currently enabled only for MT8186.

2023-04-05nvmem: core: request layout modules loadingMiquel Raynal
When a storage device like an eeprom or an mtd device probes, it registers an nvmem device if the nvmem subsystem has been enabled (bool symbol). During nvmem registration, if the device is using layouts to expose dynamic nvmem cells, the core will first try to get a reference over the layout driver callbacks. In practice there is not relationship that can be described between the storage driver and the nvmem layout. So there is no way we can enforce both drivers will be built-in or both will be modules. If the storage device driver is built-in but the layout is built as a module, instead of badly failing with an endless probe deferral loop, lets just make a modprobe call in case the driver was made available in an initramfs with of_device_node_request_module(), and offer a fully functional system to the user.

2023-04-05nvmem: core: handle the absence of expected layoutsMiquel Raynal
Make nvmem_layout_get() return -EPROBE_DEFER while the expected layout is not available. This condition cannot be triggered today as nvmem layout drivers are initialed as part of an early init call, but soon these drivers will be converted into modules and be initialized with a standard priority, so the unavailability of the drivers might become a reality that must be taken care of. Let's anticipate this by telling the caller the layout might not yet be available. A probe deferral is requested in this case. Please note this does not affect any nvmem device not using layouts, because an early check against the "nvmem-layout" container presence will return NULL in this case.

2023-04-05nvmem: core: introduce NVMEM layoutsMichael Walle
NVMEM layouts are used to generate NVMEM cells during runtime. Think of an EEPROM with a well-defined conent. For now, the content can be described by a device tree or a board file. But this only works if the offsets and lengths are static and don't change. One could also argue that putting the layout of the EEPROM in the device tree is the wrong place. Instead, the device tree should just have a specific compatible string. Right now there are two use cases: (1) The NVMEM cell needs special processing. E.g. if it only specifies a base MAC address offset and you need to add an offset, or it needs to parse a MAC from ASCII format or some proprietary format. (Post processing of cells is added in a later commit). (2) u-boot environment parsing. The cells don't have a particular offset but it needs parsing the content to determine the offsets and length.

It is far from creating a purely useful modalias string and does not seem to be used like that directly anyway, so let's try to give this helper a more meaningful name before moving there a real modalias helper (already existing under of/device.c). Also update the various documentations to refer to the strings as "aliases" rather than "modaliases" which has a real meaning in the Linux kernel. There is no functional change. Cc: Rafael J.

2023-04-05of: Fix modalias string generationMiquel Raynal
The helper generating an OF based modalias (of_device_get_modalias()) works fine, but due to the use of snprintf() internally it needs a buffer one byte longer than what should be needed just for the entire string (excluding the '\0'). Most users of this helper are sysfs hooks providing the modalias string to users. They all provide a PAGE_SIZE buffer which is way above the number of bytes required to fit the modalias string and hence do not suffer from this issue. There is another user though, of_device_request_module(), which is only called by drivers/usb/common/ulpi.c. This request module function is faulty, but maybe because in most cases there is an alternative, ULPI driver users have not noticed it. In this function, of_device_get_modalias() is called twice. The first time without buffer just to get the number of bytes required by the modalias string (excluding the null byte), and a second time, after buffer allocation, to fill the buffer. The allocation asks for an additional byte, in order to store the trailing '\0'. However, the buffer *length* provided to of_device_get_modalias() excludes this extra byte. The internal use of snprintf() with a length that is exactly the number of bytes to be written has the effect of using the last available byte to store a '\0', which then smashes the last character of the modalias string. Provide the actual size of the buffer to of_device_get_modalias() to fix this issue. Note: the "str[size - 1] = '\0';" line is not really needed as snprintf will anyway end the string with a null byte, but there is a possibility that this function might be called on a struct device_node without compatible, in this case snprintf() would not be executed. So we keep it just to avoid possible unbounded strings.

2023-03-18media: m5mols: fix off-by-one loop termination errorLinus Torvalds
The __find_restype() function loops over the m5mols_default_ffmt[] array, and the termination condition ends up being wrong: instead of stopping when the iterator becomes the size of the array it traverses, it stops after it has already overshot the array. Now, in practice this doesn't likely matter, because the code will always find the entry it looks for, and will thus return early and never hit that last extra iteration. But it turns out that clang will unroll the loop fully, because it has only two iterations (well, three due to the off-by-one bug), and then clang will end up just giving up in the middle of the loop unrolling when it notices that the code walks past the end of the array. And that made 'objtool' very unhappy indeed, because the generated code just falls off the edge of the universe, and ends up falling through to the next function, causing this warning: drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc() Fix the loop ending condition.
