Subject: [PATCH 2/3] clk: imx8mq: add hdmi_phy_27m clock as pll's reference clock
Date: Thu, 7 Mar 2019 03:41:03 +0000 [thread overview]
Message-ID: <1551929772-22633-2-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1551929772-22633-1-git-send-email-Anson.Huang@nxp.com>
There is another 27MHz OSC inside i.MX8MQ's display block and
it can be one of reference clocks of all PLLs, add it into clock
tree and also add it as PLL's reference clock.
