-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

-
-Cherry-picked from CAF QSDK repo.
-Original commit message:
-The kernel is failing in switching the timer for high resolution
-mode and clock source operates in 10ms resolution. The always-on
-property needs to be given for timer device tree node to make
-clock source working in 1ns resolution.

-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.

-
-Allow the user to choose whether to build support for all algorithms
-(default), hashes-only, or skciphers-only.
-
-The QCE engine does not appear to scale as well as the CPU to handle
-multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the
-QCE handles only 2 requests in parallel.
-
-Ipsec throughput seems to improve when disabling either family of

-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 11/11] crypto: qce - handle AES-XTS cases that qce fails
-
-QCE hangs when presented with an AES-XTS request whose length is larger
-than QCE_SECTOR_SIZE (512-bytes), and is not a multiple of it. Let the
-fallback cipher handle them.

-Subject: [PATCH 2/2] clk: fix apss cpu overclocking
-
-There's an interaction issue between the clk changes:"
-clk: qcom: ipq4019: Add the apss cpu pll divider clock node
-clk: qcom: ipq4019: remove fixed clocks and add pll clocks
-" and the cpufreq-dt.
-
-cpufreq-dt is now spamming the kernel-log with the following:
-
-[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
-for freq 761142857 (-34)
-
-This only happens on certain devices like the Compex WPJ428
-and AVM FritzBox!4040. However, other devices like the Asus
-RT-AC58U and Meraki MR33 work just fine.
-
-The issue stem from the fact that all higher CPU-Clocks
-are achieved by switching the clock-parent to the P_DDRPLLAPSS
-(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
-as part of the DDR calibration.
-
-For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
-at round 533 MHz (ddrpllsdcc = 190285714 Hz).
-
-whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
-clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
-
-This patch attempts to fix the issue by modifying
-clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
-to use a new qcom_find_freq_close() function, which returns the closest
-matching frequency, instead of the next higher. This way, the SoC in
-the FB4040 (with its max clock speed of 710.4 MHz) will no longer
-try to overclock to 761 MHz.
-
-Fixes: d83dcacea18 ("clk: qcom: ipq4019: Add the apss cpu pll divider clock node")

-Subject: [PATCH] arm: compressed: add appended DTB section
-
-This adds a appended_dtb section to the ARM decompressor
-linker script.
-
-This allows using the existing ARM zImage appended DTB support for
-appending a DTB to the raw ELF kernel.
-
-Its size is set to 1MB max to match the zImage appended DTB size limit.
-
-To use it to pass the DTB to the kernel, objcopy is used:
-
-objcopy --set-section-flags=.appended_dtb=alloc,contents \
- --update-section=.appended_dtb=<target>.dtb vmlinux
-
-This is based off the following patch:

-
-For IPQ40XX systems where the SoC watchdog is activated before linux,
-the watchdog timer may be too small for linux to finish uncompress,
-boot, and watchdog management start.
-If the watchdog is enabled, set the timeout for it to 30 seconds.
-The functionality and offsets were copied from:
-drivers/watchdog/qcom-wdt.c qcom_wdt_set_timeout & qcom_wdt_start
-The watchdog memory address was taken from:
-arch/arm/boot/dts/qcom-ipq4019.dtsi
-
-This was required on Mikrotik IPQ40XX consumer hardware using Mikrotik's
-RouterBoot bootloader.

-Subject: [PATCH] net: phy: Add Qualcom QCA807x driver
-
-This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
-
-They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s.
-
-They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC, while second one is SGMII for connection to MAC or fiber.
-
-Both models have a combo port that supports 1000BASE-X and 100BASE-FX fiber.
-
-Each PHY inside of QCA807x series has 4 digitally controlled output only pins that natively drive LED-s.
-But some vendors used these to driver generic LED-s controlled by userspace,
-so lets enable registering each PHY as GPIO controller and add driver for it.
-
-These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x boards.
