[PATCH v1 0/2] soundwire: qcom: add support for EE-aware register layout

[Mohammad Rafi Shaik]

This series adds support for execution environment (EE) aware register
layouts in the Qualcomm SoundWire master controller driver.

On SoundWire v2.0+ hardware, some controllers bank the interrupt, FIFO, and
status registers in EE-specific windows separated by a stride of 0x1000.
Typically, the driver assumes EE1, but platforms like Shikra have the
controller routed on EE0.

To support platforms with varying EEs, we:
1. Introduce the `qcom,swr-master-ee-val` DT property to configure the
   target execution environment.
2. Add remapping logic to adjust the register layout offsets by the
   EE window stride on v2.0+ hardware.
   
The first patch adds DT binding documentation for the new property, and
the second implements the EE-aware layout selection in the soundwire
driver.
