Subject: [PATCH V2] soc: imx: imx8m-blk-ctrl: Fix IMX8MN_DISPBLK_PD_ISI hang
Date:   Sun, 20 Mar 2022 15:52:12 -0500
Message-Id: <20220320205212.701548-1-aford173@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The imx8mn clock list for the ISI lists four clocks, but DOMAIN_MAX_CLKS
was set to 3.  Because of this, attempts to enable the fourth clock failed,
threw some splat, and ultimately hung.

Fixes: 7f511d514e8c ("soc: imx: imx8m-blk-ctrl: add i.MX8MN DISP blk-ctrl")
