Subject: [PATCH 0/3] clk: imx8m: Define gates for pll1/2 dividers
Date: Wed, 11 Sep 2019 15:05:26 +0300 [thread overview]
Message-ID: <cover.1568203237.git.leonard.crestez@nxp.com> (raw)
The fixed dividers for sys_pll1 and sys_pll2 on imx8m each have a gate
attached but they're currently unused so they default to "always on".
Add them to the clk tree for the sake of corectness. This could expose
bugs where parent clocks were not correctly enabled.
The new gates are added between the PLL and fixed dividers and new gates
are enumerated at the end in dt-bindings. This should ensure
compatibility, even though none of these fixed dividers are directly
referenced by peripherals anyway.
There are small differences on imx8mq because the PLL physical
implementation is also different.
