-Subject: [PATCH] ARM: dts: qcom: add gpio-ranges property
-
-This patch adds the gpio-ranges property to almost all of
-the Qualcomm ARM platforms that utilize the pinctrl-msm
-framework.
-
-The gpio-ranges property is part of the gpiolib subsystem.
-As a result, the binding text is available in section
-"2.1 gpio- and pin-controller interaction" of
-Documentation/devicetree/bindings/gpio/gpio.txt
-
-For more information please see the patch titled:
-"pinctrl: msm: fix gpio-hog related boot issues" from
-this series.

-Subject: [PATCH] crypto: qce - switch to skcipher API
-
-Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface")
-dated 20 august 2015 introduced the new skcipher API which is supposed to
-replace both blkcipher and ablkcipher. While all consumers of the API have
-been converted long ago, some producers of the ablkcipher remain, forcing
-us to keep the ablkcipher support routines alive, along with the matching
-code to expose [a]blkciphers via the skcipher API.
-
-So switch this driver to the skcipher API, allowing us to finally drop the
-blkcipher code in the near future.

-Subject: [PATCH 04/11] crypto: qce - save a sg table slot for result buf
-
-When ctr-aes-qce is used for gcm-mode, an extra sg entry for the
-authentication tag is present, causing trouble when the qce driver
-prepares the dst-results sg table for dma.
-
-It computes the number of entries needed with sg_nents_for_len, leaving
-out the tag entry. Then it creates a sg table with that number plus
-one, used to store a result buffer.
-
-When copying the sg table, there's no limit to the number of entries
-copied, so the extra slot is filled with the authentication tag sg.
-When the driver tries to add the result sg, the list is full, and it
-returns EINVAL.
-
-By limiting the number of sg entries copied to the dest table, the slot
-for the result buffer is guaranteed to be unused.

-Subject: [PATCH 09/11] crypto: qce - use cryptlen when adding extra sgl
-
-The qce crypto driver appends an extra entry to the dst sgl, to maintain
-private state information.
-
-When the gcm driver sends requests to the ctr skcipher, it passes the
-authentication tag after the actual crypto payload, but it must not be
-touched.
-
-Commit 1336c2221bee ("crypto: qce - save a sg table slot for result
-buf") limited the destination sgl to avoid overwriting the
-authentication tag but it assumed the tag would be in a separate sgl
-entry.
-
-This is not always the case, so it is better to limit the length of the
-destination buffer to req->cryptlen before appending the result buf.

-Subject: [PATCH 10/11] crypto: qce - use AES fallback for small requests
-
-Process small blocks using the fallback cipher, as a workaround for an
-observed failure (DMA-related, apparently) when computing the GCM ghash
-key. This brings a speed gain as well, since it avoids the latency of
-using the hardware engine to process small blocks.
-
-Using software for all 16-byte requests would be enough to make GCM
-work, but to increase performance, a larger threshold would be better.
-Measuring the performance of supported ciphers with openssl speed,
-software matches hardware at around 768-1024 bytes.
-
-Considering the 256-bit ciphers, software is 2-3 times faster than qce
-at 256-bytes, 30% faster at 512, and about even at 768-bytes. With
-128-bit keys, the break-even point would be around 1024-bytes.
-
-This adds the 'aes_sw_max_len' parameter, to set the largest request
-length processed by the software fallback. Its default is being set to
-512 bytes, a little lower than the break-even point, to balance the cost
-in CPU usage.

-Subject: [PATCH] mtd: spi-nor: Add support for mx25r3235f
-
-Add MTD support for the Macronix MX25R3235F SPI NOR chip from Macronix.
-The chip has 4MB of total capacity, divided into a total of 64 sectors,
-each 64KB sized. The chip also supports 4KB large sectors.
-Additionally, it supports dual and quad read modes.
-
-Functionality was verified on an HPE/Aruba AP-303 board.
