Series 2/3] ARM: dts: at91: sama7g5: Add can controllers of sama7g5 | expand

Commit Message

Hari Prasath Gujulan Elango Feb. 22, 2022, 11:39 a.m. UTC
Add support for all the six CAN controllers of sama7g5.The internal SRAM of 128KB
is split among the CAN controllers for the message RAM elements leaving a small
portion reserved for power management. The SRAM split up is as below.

Lower 64K:
        PM       13K
        can-0    17K
        can-1    17K
        can-2    17K

Higher 64K:

        can-3    17K
        can-4    17K
        can-5    17K
