Subject: [PATCH 5.2 03/45] phy: qcom-qmp: Raise qcom_qmp_phy_enable() polling delay
Date: Sun, 29 Sep 2019 15:55:31 +0200 [thread overview]
Message-ID: <20190929135025.438428669@linuxfoundation.org> (raw)
In-Reply-To: <20190929135024.387033930@linuxfoundation.org>
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().
