Devi Priya May 26, 2023, 3:31 p.m. UTC 
Add the initial device tree support for the Reference Design Platform (RDP)
453 based on IPQ9574 family of SoCs. This patch adds support for Console
UART, SPI NOR and SMPA1 regulator node.

BTW what's the naming scheme for IPQ?

IPQabcd

'a' - tier
'b' - 0/5 - network generation dependent?
'cd' - model

?

Hi konrad,

Below is the naming scheme,
IPQabcd
a-> product category(5-Immersive home, 6-Home, 9-Networking Pro)
b-> generation (5-Alder)
c-> SKU customization (0-base SKU)
d-> #chains

Thanks,
Devi Priya
