[PATCH v2 0/4] AM654: Add pinmux support

[Vignesh R]

Add pinmux definitions and pinctrl regions for AM654 SoCs
and enable uart and i2c.

v2:
Add only minimum needed macros in dt-bindings include file
New patches to illustrate pinmux using uart and i2c

I wonder if we can put up a next branch that is available in linux-next

[PATCH v2 2/4] arm64: dts: ti: k3-am65: Add pinctrl regions

[Vignesh R]

From: Tero Kristo <t-kristo@ti.com>

Add pinctrl regions for the main and wkup mmr.

The range for main pinctrl region contains a gap
at offset 0x2e4, and because of this, the pinctrl
range is split into two sections.
