Subject[PATCH 5.2 03/45] phy: qcom-qmp: Raise qcom_qmp_phy_enable() polling delay
Date
From: Marc Gonzalez <marc.w.gonzalez@free.fr>

[ Upstream commit 5206026404190125436f81088eb3667076e56083 ]

readl_poll_timeout() calls usleep_range() to sleep between reads.
usleep_range() doesn't work efficiently for tiny values.

Raise the polling delay in qcom_qmp_phy_enable() to bring it in line
with the delay in qcom_qmp_phy_com_init().
