TDA4VM-Q1: TDA4VM-Q1 custom board PMIC changes in SDK Linux adas

Part Number: TDA4VM-Q1
Other Parts Discussed in Thread: TPS22965

Hello TI team,

I have TDA4VM-Q1 HS based custom board where i am trying to do board bring up.

I have refered some TI E2E reference for custom board bringup where i came to know like Pinmux, PMIC, DDR & UART related changes are need.

I would like to get a support for PMIC related code in k3-j721e-r5-common-proc-board.dts file and in other related files as well.

I am using PMICs TPS65941213 & TPS6594111 along with Load switchs TPS22965 as well as LDO TLV73318.

Kindly provide a guidance or support to update required files.

The EVM has TPS6594x as well. As far as adaptive voltage scaling feature from PMIC is concerned you can re-use the node.

I am assuming that TPS6594x feeds into A72 aka compute cluster:

VDD_CPU_AVS regulator is the board design similar to EVM?

Hello Keerthy,

Thanks for the reply.

I have same VDD_CPU_AVS_REG power source in my custom board as per below link:

e2e.ti.com/.../DRA829_5F00_TDA4VM_5F00_3Ph_5F00_Dual_5F00_Leo2.0_5F00_PDN_2D00_0C_5F00_v0.18.pdf

Harshil,

Then you can use the same dts node as in the EVM dts file. No changes needed for AVS from PMIC.
