[PATCH v6 4/4] arm: arm64: dts: add property snps incr burst type adjustment

[Pengbo Mu]

Property "snps,incr-burst-type-adjustment = <x>, <y>..." for USB3.0
DWC3.When only one value means INCRx mode with fix burst type.
When more than one value, means undefined length burst mode, USB
controller can use the length less than or equal to the largest
enabled burst length.

While enabling undefined length INCR burst type and INCR16 burst type,
get better write performance on NXP Layerscape platforms: around 3%
improvement (from 364MB/s to 375MB/s).

Hi ,
I am sorry for I don't understand what you mean .
This patch fixed the dts files of arm32 & arm64 , so I named the title like "arm: arm64: dts ***" .
Is this something wrong ? If yes , pls tell me and I will fix it !

Thanks,

updated from "arm64: dts: dwc3" to "dt-bindings: usb: dwc3" though.

Can you resend the series so I can apply?

[PATCH v6 4/4] arm: arm64: dts: add property snps incr burst type adjustment

[Pengbo Mu]

Property "snps,incr-burst-type-adjustment = <x>, <y>..." for USB3.0
DWC3.When only one value means INCRx mode with fix burst type.
When more than one value, means undefined length burst mode, USB
controller can use the length less than or equal to the largest
enabled burst length.

While enabling undefined length INCR burst type and INCR16 burst type,
get better write performance on NXP Layerscape platforms: around 3%
improvement (from 364MB/s to 375MB/s).

Changes in v5:
 - add support for ls1021a, ls1012a, ls1046a, ls1088a, ls1021a
 - update ls208xa support according to code base change
Changes in v4:
 - change definition for this property.
Changes in v3:
 - add new property for INCR burst in usb node.
