[PATCH 0/3] arm64: dts: ti: k3: Add additioal regs for DMA components

[Vignesh Raghavendra]

This adds additional reg ranges which are not directly used by Linux but
by other components like U-Boot

[Vignesh Raghavendra]

From: Manorit Chawdhry <m-chawdhry@ti.com>

Add additional reg properties for UDMA and RingAcc nodes which are
mostly used by bootloader components before Device Manager firmware
services are available, in order to setup DMA transfers.

Hi Vignesh/Manorit,

Thanks for the patch. BCDMA regions don't seem to match the TRM for 
AM65, can you recheck?

AM65 TRM mentions TCHAN region size as 0x10000 in the memory map. Can 
you confirm if this is correct and send a v2 if not?

> +			      <0x0 0x30c00000 0x0 0x8000>,

Same here, TRM says size is 0x10000.

> +			      <0x0 0x30d00000 0x0 0x4000>;

Same here, TRM says size is 0x8000.

Above don't match J721E TRM, which says TCHAN has size 0x10000.

Same here, TRM says 0x8000.
I did not check J7200/J721S2 TRMs, please do.

[PATCH 3/3] arm64: dts: ti: k3-am6*: Add additional regs for DMA components

[Vignesh Raghavendra]

Add additional reg properties for BCDMA and PKTDMA nodes which are
mostly used by bootloader components before Device Manager firmware
services are available, in order to setup DMA transfers.

Re: [PATCH 3/3] arm64: dts: ti: k3-am6*: Add additional regs for DMA components

[Jai Luthra]

[-- Attachment #1: Type: text/plain, Size: 8069 bytes --]

Hi Vignesh,

Thanks for the patch, PKTDMA address region sizes don't seem to match 
the TRM. Not sure if the patch is wrong or TRM is wrong.

BCDMA ranges LGTM, but PDMA ranges below are not matching with the TRM.

This matches TRM.

PKGTMA RFLOW region range is 0x1000 in the TRM.

Same issue as AM62, the TRM mentions a different size for these regions.
