From: Marc Gonzalez Date: Thu, 13 Jun 2019 11:32:08 +0000 (+0200) Subject: phy: qcom-qmp: Raise qcom_qmp_phy_enable() polling delay X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5206026404190125436f81088eb3667076e56083;p=linux.git phy: qcom-qmp: Raise qcom_qmp_phy_enable() polling delay 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().
