Subject: [PATCH V2] clk: imx: pll14xx: fix clk_pll14xx_wait_lock
Date: Mon, 9 Dec 2019 08:19:55 +0000	[thread overview]
Message-ID: <1575879445-15386-1-git-send-email-peng.fan@nxp.com> (raw)

From: Peng Fan <peng.fan@nxp.com>

The usage of readl_poll_timeout is wrong, the 3rd parameter(cond)
should be "val & LOCK_STATUS" not "val & LOCK_TIMEOUT_US",
It is not check whether the pll locked, LOCK_STATUS reflects the mask,
not LOCK_TIMEOUT_US.
