- property
-
-This patch for the DesignWare AHB Central
-Direct Memory Access Controller adds the dma
-protection control property:
-	"snps,dma-protection-control"
-
-as well as the properties specific values defines into
-a new include file: include/dt-bindings/dma/dw-dmac.h
-
-Note: The protection control signals are one-to-one
-mapped to the AHB HPROT[1:3] signals for this controller.
-The HPROT0 (Data Access) is always hardwired to 1.

-Subject: [PATCH 03/15] crypto: drop mask=CRYPTO_ALG_ASYNC from 'cipher' tfm
- allocations
-
-'cipher' algorithms (single block ciphers) are always synchronous, so
-passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_cipher() has no
-effect.  Many users therefore already don't pass it, but some still do.
-This inconsistency can cause confusion, especially since the way the
-'mask' argument works is somewhat counterintuitive.
-
-Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
-
-This patch shouldn't change any actual behavior.

-
-This function is internal to the DMA API implementation. Instead use
-the DMA API to properly unmap. Note that the DMA API usage in this
-driver is a disaster and urgently needs some work - it is missing all
-the unmaps, seems to do a secondary map where it looks like it should
-to a unmap in one place to work around cache coherency and the
-directions passed in seem to be partially wrong.

-
-using_sd is used as a stand-in for sa_command_0.bf.scatter
-that we need to set anyway, so we might as well just prevent
-double-accounting.

-Subject: [PATCH] usb: xhci: add firmware loader for uPD720201 and uPD720202
- w/o ROM
-
-This patch adds a firmware loader for the uPD720201K8-711-BAC-A
-and uPD720202K8-711-BAA-A variant. Both of these chips are listed
-in Renesas' R19UH0078EJ0500 Rev.5.00 "User's Manual: Hardware" as
-devices which need the firmware loader on page 2 in order to
-work as they "do not support the External ROM".
-
-The "Firmware Download Sequence" is describe in chapter
-"7.1 FW Download Interface" R19UH0078EJ0500 Rev.5.00 page 131.
-
-The firmware "K2013080.mem" is available from a USB3.0 Host to
-PCIe Adapter (PP2U-E card) "Firmware download" archive. An
-alternative version can be sourced from Netgear's WNDR4700 GPL
-archives.
-
-The release notes of the PP2U-E's "Firmware Download" ver 2.0.1.3
-(2012-06-15) state that the firmware is for the following devices:
- - uPD720201 ES 2.0 sample whose revision ID is 2.
- - uPD720201 ES 2.1 sample & CS sample & Mass product, ID is 3.
- - uPD720202 ES 2.0 sample & CS sample & Mass product, ID is 2.
-

-Subject: [PATCH] hwmon: tc654: add thermal_cooling device
-
-This patch adds a thermaL_cooling device to the tc654 driver.
-This allows the chip to be used for DT-based cooling.

-Subject: [PATCH 24/33] MIPS: ath79: make specifying the reference clock in DT
- optional
-
-It can be autodetected for many SoCs using the strapping options.
-If the clock is specified in DT, the autodetected value is ignored

-Subject: [PATCH 26/33] MIPS: ath79: export switch MDIO reference clock
-
-On AR934x, the MDIO reference clock can be configured to a fixed 100 MHz
-clock. If that feature is not used, it defaults to the main reference
-clock, like on all other SoC.

-Subject: [PATCH 30/33] MIPS: ath79: drop platform device registration code
-
-With the target now being fully OF based, we can drop the legacy platform
-device registration code. All devices and their drivers are now probed
-via OF.

-There are currently 1200+ instances of using platform_get_resource()

-
-This patch wraps these two calls in a single helper. Thanks to that
-we don't have to declare a local variable for struct resource * and can
-omit the redundant argument for resource type. We also have one
-function call less.

-
-This patch adds driver for SPI controller found in Qualcomm Atheros
-AR934x/QCA95xx SoCs.
-This controller is a superset of the already supported qca,ar7100-spi.
-Besides the bit-bang mode in spi-ath79.c, this new controller added
-a new "shift register" mode, allowing faster spi operations.

-On AR934x this UART is usually not initialized by the bootloader
-as it is only used as a secondary serial port while the primary
-UART is a newly introduced NS16550-compatible.
-In order to make use of the ar933x-uart on AR934x without RTS/CTS
-hardware flow control, one needs to set the
-UART_CS_{RX,TX}_READY_ORIDE bits as other than on AR933x where this
-UART is used as primary/console, the bootloader on AR934x typically
-doesn't set those bits.
-Setting them explicitely on AR933x should not do any harm, so just
-set them unconditionally.

-Emulate half-duplex operation and use mctrl_gpio to add support for
-RS485 tranceiver with transmit/receive switch hooked to RTS GPIO line.
-This is needed to make use of the RS485 port found on Teltonika RUT955.

-v2: use bool to indicate ongoing half-duplex send, use it afterwards
-    to decide whether we've just been in a send operation.

-Subject: MIPS: pci-ar724x: add QCA9550 reset sequence
-
-The QCA9550 family of SoCs have a slightly different reset
-sequence compared to older chips.
-
-Normally the bootloader performs this sequence, however
-some bootloader implementation expect the operating system
-to clear the reset.
-
-Also get the resets from OF to support handling of the second
-PCIe root-complex on the QCA9558.

-Subject: [PATCH] mdio_bus: don't use managed reset-controller
-
-Geert Uytterhoeven reported that using devm_reset_controller_get leads
-to a WARNING when probing a reset-controlled PHY. This is because the
-device devm_reset_controller_get gets supplied is not actually the
-one being probed.
-
-Acquire an unmanaged reset-control as well as free the reset_control on
-unregister to fix this.

-Subject: [PATCH] phy/mdio-bitbang: prevent rescheduling during command
-
-It seems some phys have some maximum timings for accessing the MDIO line,
-resulting in bit errors under cpu stress. Prevent this from happening by
-disabling interrupts when sending commands.
