Subject: [PATCH 04/10] clk: imx8mp: Define gates for pll1/2 fixed dividers
Date: Thu, 12 Mar 2020 17:01:26 +0800 [thread overview]
Message-ID: <1584003692-25523-5-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1584003692-25523-1-git-send-email-peng.fan@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
Inspried from
commit e8688fe8df7d ("clk: imx8mn: Define gates for pll1/2 fixed dividers")
On imx8mp there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.
Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.
