Add patches for linux-5.4. The patches are from NXP LSDK-20.04 release which was tagged LSDK-20.04-V5.4. https://source.codeaurora.org/external/qoriq/qoriq-components/linux/ For boards LS1021A-IOT, and Traverse-LS1043 which are not involved in LSDK, port the dts patches from 4.14. The patches are sorted into the following categories: 301-arch-xxxx 302-dts-xxxx 303-core-xxxx 701-net-xxxx 801-audio-xxxx 802-can-xxxx 803-clock-xxxx 804-crypto-xxxx 805-display-xxxx 806-dma-xxxx 807-gpio-xxxx 808-i2c-xxxx 809-jailhouse-xxxx 810-keys-xxxx 811-kvm-xxxx 812-pcie-xxxx 813-pm-xxxx 814-qe-xxxx 815-sata-xxxx 816-sdhc-xxxx 817-spi-xxxx 818-thermal-xxxx 819-uart-xxxx 820-usb-xxxx 821-vfio-xxxx Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>

Subject: [PATCH] arm64: dts: fsl: ls1028a: Disable eno3 and make swp5 the
|
|
Felix CPU port
|
|
|
|
This patch returns to the switch port setup from BSP 0.2, where the
|
|
switch only had a single Ethernet connection to the CPU, via a tagging
|
|
interface. Choose eno2 for this purpose, as it has higher bandwidth and
|
|
also supports TSN offloads.
|
|
|
|
The reason is that the switch is not able to do DSA tags on 2 CPU ports
|
|
at the same time, and it is confusing to have so many ports with no
|
|
clear indication which should be used for what (a "data" port and a
|
|
"control" port).
|
|
|
|
We don't revert to the BSP 0.2 RCW configuration, however. The ENETC
|
|
port 3 is still enabled in the RCW, however it is not probed by Linux by
|
|
default, since the large majority of use cases will not need it. For
|
|
those that do (like originating 802.1CB traffic from the CPU), it can be
|
|
enabled back by simply reverting this device tree change.
