[PATCH 0/3] Fix reg ranges for dma-controller node

[PATCH 0/3] Fix reg ranges for dma-controller node

[Jayesh Choudhary]

The dma-controller node 'main_pktdma' has few memory regions with
wrong sizes.

DMASS0_PKTDMA_RINGRT is marked as 4MB region when it is actually a 2MB
region. Similarly, DMASS0_PKTDMA_TCHANRT is marked as 256KB region but
the actual size is 128KB as shown in TRM in the section for Main Memory
Map (Table 2-1)

Fix these region across AM62, AM62A and AM62P (which is also used in
J722S)

TRM:

AM625: <https://www.ti.com/lit/pdf/spruiv7>
AM62A7: <https://www.ti.com/lit/pdf/spruj16>
AM62P: <https://www.ti.com/lit/pdf/spruj83>
J722S: <https://www.ti.com/lit/zip/sprujb3>

[PATCH 1/3] arm64: dts: ti: k3-am62-main: Fix the reg-range for dma-controller

[Jayesh Choudhary]

The TX Channel Realtime Registers region 'tchanrt' is 128KB and Ring
Realtime Registers region 'ringrt' is 2MB as shown in memory map in
the TRM[0]. So fix ranges for those reg-regions.

Thanks for this fix Jayesh

Minor one, but it will be better to say that you are fixing these 
register ranges for  PKTDMA .

Something like that

For PKTDMA, The TX Channel Realtime Registers region 'tchanrt' ....

Also, it will help reviewer if you can mention which section in TRM[0], 
holding memory map .

If you are doing v2 then please take care of above in commit message.

rest for whole series

LGTM

The cover-letter[0] for the series does mention that the changes are for
DMASS0_PKTDMA_RINGRT and DMASS0_PKTDMA_TCHANRT with the current and
correct region size.
It also mentions the section and the Table from where we can check them.
{*** section for Main Memory Map (Table 2-1)}

[0]: https://lore.kernel.org/all/20240405085208.32227-1-j-choudhary@ti.com/

It was same check across all platform so added in cover letter.
But I will add that in each patch.

Thanks,
Jayesh
