[RFC PATCH 0/3] Enable ESMs and related PMIC

[RFC PATCH 0/3] Enable ESMs and related PMIC

[Udit Kumar]

This enables the ESMs and the associated PMIC.
Programming these bits is a requirement to make the watchdog actually reset the board.

Patch 3/3 is already available in upstream kernel.
While above sync is done, sending this series as RFC.

[RFC PATCH 2/3] arm: dts: k3-j7200: Add ESM PMIC support for tps659413

[Udit Kumar]

From: Gowtham Tammana <g-tammana@ti.com>

On J7200 processor board MCU_SAFETY_ERROR signal is routed to PMIC for
ESM error handling. The PMIC resets the board on receipt of the signal.
Enable the support for the board by adding ESM PMIC node.

[RFC PATCH 3/3] arm: dts: k3-j7200: Add bootph for esm and pmic nodes

[Udit Kumar]

In order to get esm and pmic probed by R5 SPL, these nodes should
be have bootph pre ram property.

However these changes are committed in kernel with following sha-id
b903ab269e67 (arm64: dts: ti: k3-j7200: Add bootph-* properties)
and bdb543b1664b (arm64: dts: ti: k3-j7200-evm*: Add bootph-* properties).

While we wait for above committed to get synched with u-boot.
Meanwhile add bootph in these nodes.
