kernel: drop everything not on kernel version 4.14

Browse Source 
* Remove testing patches for kernel version 4.19
 * remove targets ar7, ixp4xx, orion
Those targets are still on kernel 4.9, patches for 4.14 were not ready
in time. They may be readded once people prepare and test patches for
kernel 4.14.

Subject: dmaengine: dw-dmac: implement dma protection control setting
This patch adds a new device-tree property that allows to
specify the dma protection control bits for the all of the
DMA controller's channel uniformly.
Setting the "correct" bits can have a huge impact on the
PPC460EX and APM82181 that use this DMA engine in combination
with a DesignWare' SATA-II core (sata_dwc_460ex driver).
In the OpenWrt Forum, the user takimata reported that:
|It seems your patch unleashed the full power of the SATA port.
|Where I was previously hitting a really hard limit at around
|82 MB/s for reading and 27 MB/s for writing, I am now getting this:
|
|root@OpenWrt:/mnt# time dd if=/dev/zero of=tempfile bs=1M count=1024
|1024+0 records in
|1024+0 records out
|real 0m 13.65s
|user 0m 0.01s
|sys 0m 11.89s
|
|root@OpenWrt:/mnt# time dd if=tempfile of=/dev/null bs=1M count=1024
|1024+0 records in
|1024+0 records out
|real 0m 8.41s
|user 0m 0.01s
|sys 0m 4.70s
|
|This means: 121 MB/s reading and 75 MB/s writing!
|
|The drive is a WD Green WD10EARX taken from an older MBL Single.
|I repeated the test a few times with even larger files to rule out
|any caching, I'm still seeing the same great performance. OpenWrt is
|now completely on par with the original MBL firmware's performance.
Another user And.short reported:
|I can report that your fix worked! Boots up fine with two
|drives even with more partitions, and no more reboot on
|concurrent disk access!
A closer look into the sata_dwc_460ex code revealed that
the driver did initally set the correct protection control
bits. However, this feature was lost when the sata_dwc_460ex
driver was converted to the generic DMA driver framework.

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.

Subject: [PATCH 04/15] crypto4xx_core: don't abuse __dma_sync_page
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.

Subject: [PATCH 13/15] crypto: crypto4xx - fix AES CTR blocksize value
This patch fixes a issue with crypto4xx's ctr(aes) that was
discovered by libcapi's kcapi-enc-test.sh test.
The some of the ctr(aes) encryptions test were failing on the
non-power-of-two test:
kcapi-enc - Error: encryption failed with error 0
kcapi-enc - Error: decryption failed with error 0
[FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits):
original file (1d100e..cc96184c) and generated file (e3b0c442..1b7852b855)
[FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits)
(openssl generated CT): original file (e3b0..5) and generated file (3..8e)
[PASSED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (128 bits)
(openssl generated PT)
[FAILED: 32-bit - 5.1.0-rc1+] 15 bytes: STDIN / STDOUT enc test (password):
original file (1d1..84c) and generated file (e3b..852b855)
But the 16, 32, 512, 65536 tests always worked.
Thankfully, this isn't a hidden hardware problem like previously,
instead this turned out to be a copy and paste issue.
With this patch, all the tests are passing with and
kcapi-enc-test.sh gives crypto4xx's a clean bill of health:
"Number of failures: 0" :).

Subject: [PATCH 14/15] crypto: crypto4xx - fix blocksize for cfb and ofb
While the hardware consider them to be blockciphers, the
reference implementation defines them as streamciphers.
Do the right thing and set the blocksize to 1. This
was found by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS.
This fixes the following issues:
skcipher: blocksize for ofb-aes-ppc4xx (16) doesn't match generic impl (1)
skcipher: blocksize for cfb-aes-ppc4xx (16) doesn't match generic impl (1)

Subject: [PATCH 15/15] crypto: crypto4xx - block ciphers should only accept
complete blocks
The hardware automatically zero pads incomplete block ciphers
blocks without raising any errors. This is a screw-up. This
was noticed by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS tests that
sent a incomplete blocks and expect them to fail.
This fixes:
cbc-aes-ppc4xx encryption unexpectedly succeeded on test vector
"random: len=2409 klen=32"; expected_error=-22, cfg="random:
may_sleep use_digest src_divs=[96.90%@+2295, 2.34%@+4066,
0.32%@alignmask+12, 0.34%@+4087, 0.9%@alignmask+1787, 0.1%@+3767]
iv_offset=6"
ecb-aes-ppc4xx encryption unexpectedly succeeded on test vector
"random: len=1011 klen=32"; expected_error=-22, cfg="random:

From 419992bae5aaa4e06402e0b7c79fcf7bcb6b4764 Mon Sep 17 00:00:00 2001
From: Christian Lamparter <chunkeey@googlemail.com>
Date: Thu, 2 Jun 2016 00:48:46 +0200
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.
If someone from Renesas is listening: It would be great, if these
firmwares could be added to linux-firmware.git.

From: Jonas Gorski <jonas.gorski@gmail.com>
List-Id: linux-mips <linux-mips.eddie.linux-mips.org>
Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.

Subject: [PATCH 18/33] MIPS: pci-ar71xx: convert to OF
With the ath79 target getting converted to pure OF, we can drop all the
platform data code and add the missing OF bits to the driver. We also add
a irq domain for the PCI/e controllers cascade, thus making it usable from
dts files.

Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
With the ath79 target getting converted to pure OF, we can drop all the
platform data code and add the missing OF bits to the driver. We also add
a irq domain for the PCI/e controllers cascade, thus making it usable from
dts files.

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.

From dce930fba8ad3a90ccd164f199e57c2d61937ccd Mon Sep 17 00:00:00 2001
From: John Crispin <john@phrozen.org>
Date: Sat, 23 Jun 2018 15:12:38 +0200
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.

From 00e4313da4609074fff134e61dd9ffe3fd37474d Mon Sep 17 00:00:00 2001
From: John Crispin <john@phrozen.org>
Date: Sun, 24 Jun 2018 09:39:41 +0200
Subject: [PATCH 31/33] MIPS: ath79: drop !OF clock code
With the target now being fully OF based, we can drop the legacy clock
registration code. All clocks are now probed via devicetree.

Subject: [PATCH 32/33] MIPS: ath79: sanitize symbols
We no longer need to select which SoCs are supported as the whole arch
code is always built. So lets drop all the SoC symbols

From 66e584435ac0de6e0abeb6d7166fe4fe25d6bb73 Mon Sep 17 00:00:00 2001
From: Jonas Gorski <jogo@openwrt.org>
Date: Tue, 16 Jun 2015 13:15:08 +0200
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.

Subject: [PATCH] ARM: dts: BCM5301X: Specify flash partitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Most devices use Broadcom standard partitions which allows them to be
described with the "brcm,bcm947xx-cfe-partitions". Exceptions are:
1) TP-LINK devices which use "os-image" partition with TRX containing
kernel only + separated rootfs partition.
2) Asus RT-AC87U with custom "asus" partition.
This commit also removes undocumented and unsupported linux,part-probe
binding which got accidentally upstreamed while describing SPI
controller.

Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Phicomm K3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This router has BCM4709C0 SoC, 128 MiB NAND flash (MX30LF1G18AC-TI),
512 MiB memory and 3 x LAN and 1 x WAN ports. WiFi chips are
BCM4366C0 x 2. The router has a small LCD and 3 capactive keys driven by
a PIC microcontroller, which is in turn wired to UART1 of main board.
