Subject: [PATCH v2 1/2] ARM: dts: imx6q-tbs2910: Pass phy-reset-duration

From: Fabio Estevam <[email-masked]>
Date: Thu, 25 Jun 2020 08:18:45 -0300

According to the AR8035 datasheet:

"When using crystal, the clock is generated internally after power is
stable. For a reliable power on reset, suggest to keep asserting the reset
low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms
requirement is satisfied."

Pass the 'phy-reset-duration' property to meet such requirement.
