[Mukesh Ojha <quic_mojha@quicinc.com>]

Intention of this series to support multiple download mode and

Also, this series should be applied on
https://lore.kernel.org/lkml/1678979666-551-1-git-send-email-quic_mojha@quicinc.com/

Changes in v4:
  - val should be shifted within the function [srinivas.kandagatla]
    i.e new = (old & ~mask) | (val << ffs(mask) - 1);
  - Added Acked-by [linus.walleij] on pinctrl change.

Changes in v3 : https://lore.kernel.org/lkml/1679070482-8391-1-git-send-email-quic_mojha@quicinc.com/
