[PATCH v2 0/2] Fix PHY init timeout issues

From: Elad Nachman
Date: Thu Feb 15 2024 - 11:17:23 EST


From: Elad Nachman <enachman@xxxxxxxxxxx>

Fix PHY init timeout issues:

1. Clock Stability issue causing PHY timeout

2. Timeout taking longer than needed on AC5X.
Solve by constantly testing the PHY init bit
until it toggles, but up to 100X timeout factor.

v2:
1) convert polling loop to read_poll_timeout()
for both patches.

Elad Nachman (2):
mmc: xenon: fix PHY init clock stability
mmc: xenon: add timeout for PHY init complete
