[PATCH 5.15 059/244] clk: imx: imx8qxp: Fix elcdif_pll clock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Robert Chiras <robert.chiras@xxxxxxx>

[ Upstream commit 15cee75dacb82ade710d61bfd536011933ef9bf2 ]

Move the elcdif_pll clock initialization before the lcd_clk, since the
elcdif_clk needs to be initialized ahead of lcd_clk, being its parent.
This change fixes issues with the LCD clocks during suspend/resume.

Fixes: babfaa9556d7 ("clk: imx: scu: add more scu clocks")
