+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.

+
+This patch adds the necessary MDIO interface node
+to the Qualcomm IPQ4019 DTSI.
+
+Built-in QCA8337N switch is managed using it,
+and since we have a driver for it lets add it.

+Set the CRYPTO_ALG_KERN_DRIVER_ONLY flag to all algorithms exposed by

+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.

+
+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.

+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.
+

+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:

+Subject: [PATCH 2/2] arm: compressed: set ipq40xx watchdog to allow boot
+
+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.

+Subject: [PATCH] dts: ipq4019: add ethernet essedma node
+
+This patch adds the device-tree node for the ethernet
+interfaces.
+
+Note: The driver isn't anywhere close to be upstream,
+so the info might change.
