2021-01-06ARM: dts: sun8i-v3: Add support for the SL631 Action Camera with IMX179Paul Kocialkowski
The SL631 is a family of Allwinner V3 action cameras sold under various names, such as SJCAM SJ4000 Air or F60 Action Camera. Devices in this family share a common board design but can be found with different image sensors, including the IMX179 and the OV4689. This adds support for a common dtsi for the SL631 family as well as a specific dts for the IMX179 fashion, which will later be populated with an IMX179 node when a driver is available. Features that were tested on the device include: - UART debug - MMC - USB peripheral (e.g. g_ether) - Buttons - SPI NOR flash Note that the exact designer/vendor of these boards is unknown.

2021-01-06ARM: dts: sun8i-v3s: Add the V3s NMI IRQ controllerPaul Kocialkowski
The V3s/V3 has a NMI interrupt controller, mainly used for the AXP209. Its address follows the system controller block, which was previously incorrectly described as spanning over 0x1000 address bytes. Even though this is what the Allwinner documentation indicates, precedence from other SoCs such as the R40 suggests that this is not actually the case. This reduces the system controller address span up to the NMI controller and adds a node for the controller, with its dedicated compatible. While the interrupt number was found in Allwinner's documentation, the address for the controller is specified in any Allwinner SDK supporting sun8iw8 (V3/V3s) at: drivers/power/axp_power/axp20/axp20-board.c It was tested to work on a V3 board with an AXP209 connected to the NMI interrupt line.

2021-01-03soc: samsung: exynos-chipid: convert to driver and merge exynos-asvKrzysztof Kozlowski
The Exynos Chip ID driver on Exynos SoCs has so far only informational purpose - to expose the SoC device in sysfs. No other drivers depend on it so there is really no benefit of initializing it early. The code would be the most flexible if converted to a regular driver. However there is already another driver - Exynos ASV (Adaptive Supply Voltage) - which binds to the device node of Chip ID. The solution is to convert the Exynos Chip ID to a built in driver and merge the Exynos ASV into it. This has several benefits: 1. Although the Exynos ASV driver binds to a device node present in all Exynos DTS (generic compatible), it fails to probe except on the supported ones (only Exynos5422). This means that the regular boot process has a planned/normal device probe failure. Merging the ASV into Chip ID will remove this probe failure because the final driver will always bind, just with disabled ASV features. 2. Allows to use dev_info() as the SoC bus is present (since core_initcall). 3. Could speed things up because of execution of Chip ID code in a SMP environment (after bringing up secondary CPUs, unlike early_initcall), This reduces the amount of work to be done early, when the kernel has to bring up critical devices. 5. Makes the Chip ID code defer-probe friendly, Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201207190517.262051-5-krzk@kernel.org Reviewed-by: Pankaj Dubey <pankaj.dubey@samsung.com>
2021-01-03crypto: arm/blake2b - add NEON-accelerated BLAKE2bEric Biggers
Add a NEON-accelerated implementation of BLAKE2b. On Cortex-A7 (which these days is the most common ARM processor that doesn't have the ARMv8 Crypto Extensions), this is over twice as fast as SHA-256, and slightly faster than SHA-1. It is also almost three times as fast as the generic implementation of BLAKE2b: Algorithm Cycles per byte (on 4096-byte messages) =================== ======================================= blake2b-256-neon 14.0 sha1-neon 16.3 blake2s-256-arm 18.8 sha1-asm 20.8 blake2s-256-generic 26.0 sha256-neon 28.9 sha256-asm 32.0 blake2b-256-generic 38.9 This implementation isn't directly based on any other implementation, but it borrows some ideas from previous NEON code I've written as well as from chacha-neon-core.S. At least on Cortex-A7, it is faster than the other NEON implementations of BLAKE2b I'm aware of (the implementation in the BLAKE2 official repository using intrinsics, and Andrew Moon's implementation which can be found in SUPERCOP). It does only one block at a time, so it performs well on short messages too. NEON-accelerated BLAKE2b is useful because there is interest in using BLAKE2b-256 for dm-verity on low-end Android devices (specifically, devices that lack the ARMv8 Crypto Extensions) to replace SHA-1. On these devices, the performance cost of upgrading to SHA-256 may be unacceptable, whereas BLAKE2b-256 would actually improve performance. Although BLAKE2b is intended for 64-bit platforms (unlike BLAKE2s which is intended for 32-bit platforms), on 32-bit ARM processors with NEON, BLAKE2b is actually faster than BLAKE2s. This is because NEON supports 64-bit operations, and because BLAKE2s's block size is too small for NEON to be helpful for it. The best I've been able to do with BLAKE2s on Cortex-A7 is 18.8 cpb with an optimized scalar implementation. (I didn't try BLAKE2sp and BLAKE3, which in theory would be faster, but they're more complex as they require running multiple hashes at once. Note that BLAKE2b already uses all the NEON bandwidth on the Cortex-A7, so I expect that any speedup from BLAKE2sp or BLAKE3 would come only from the smaller number of rounds, not from the extra parallelism.) For now this BLAKE2b implementation is only wired up to the shash API, since there is no library API for BLAKE2b yet. However, I've tried to keep things consistent with BLAKE2s, e.g. by defining blake2b_compress_arch() which is analogous to blake2s_compress_arch() and could be exported for use by the library API later if needed.

2021-01-03crypto: arm/blake2s - add ARM scalar optimized BLAKE2sEric Biggers
Add an ARM scalar optimized implementation of BLAKE2s. NEON isn't very useful for BLAKE2s because the BLAKE2s block size is too small for NEON to help. Each NEON instruction would depend on the previous one, resulting in poor performance. With scalar instructions, on the other hand, we can take advantage of ARM's "free" rotations (like I did in chacha-scalar-core.S) to get an implementation get runs much faster than the C implementation. Performance results on Cortex-A7 in cycles per byte using the shash API: 4096-byte messages: blake2s-256-arm: 18.8 blake2s-256-generic: 26.0 500-byte messages: blake2s-256-arm: 20.3 blake2s-256-generic: 27.9 100-byte messages: blake2s-256-arm: 29.7 blake2s-256-generic: 39.2 32-byte messages: blake2s-256-arm: 50.6 blake2s-256-generic: 66.2 Except on very short messages, this is still slower than the NEON implementation of BLAKE2b which I've written; that is 14.0, 16.4, 25.8, and 76.1 cpb on 4096, 500, 100, and 32-byte messages, respectively. However, optimized BLAKE2s is useful for cases where BLAKE2s is used instead of BLAKE2b, such as WireGuard. This new implementation is added in the form of a new module blake2s-arm.ko, which is analogous to blake2s-x86_64.ko in that it provides blake2s_compress_arch() for use by the library API as well as optionally register the algorithms with the shash API.

2021-01-03crypto: arm/chacha-neon - add missing counter incrementArd Biesheuvel
Commit 86cd97ec4b943af3 ("crypto: arm/chacha-neon - optimize for non-block size multiples") refactored the chacha block handling in the glue code in a way that may result in the counter increment to be omitted when calling chacha_block_xor_neon() to process a full block. This violates the skcipher API, which requires that the output IV is suitable for handling more input as long as the preceding input has been presented in round multiples of the block size. Also, the same code is exposed via the chacha library interface whose callers may actually rely on this increment to occur even for final blocks that are smaller than the chacha block size. So increment the counter after calling chacha_block_xor_neon().

2020-12-30ARM: dts; gta04: SPI panel chip select is active lowH. Nikolaus Schaller
With the arrival of commit 2fee9583198eb9 ("spi: dt-bindings: clarify CS behavior for spi-cs-high and gpio descriptors") it was clarified what the proper state for cs-gpios should be, even if the flag is ignored. The driver code is doing the right thing since 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors") The chip-select of the td028ttec1 panel is active-low, so we must omit spi-cs-high; attribute (already removed by separate patch) and should now use GPIO_ACTIVE_LOW for the client device description to be fully consistent.

2020-12-29local64.h: make <asm/local64.h> mandatoryRandy Dunlap
Make <asm-generic/local64.h> mandatory in include/asm-generic/Kbuild and remove all arch/*/include/asm/local64.h arch-specific files since they only #include <asm-generic/local64.h>. This fixes build errors on arch/c6x/ and arch/nios2/ for block/blk-iocost.c. Build-tested on 21 of 25 arch-es. (tools problems on the others) Yes, we could even rename <asm-generic/local64.h> to <linux/local64.h> and change all #includes to use <linux/local64.h> instead.
