[PATCH v2] clk: imx8mq: Mark AHB clock as critical
From: Abel Vesa <hidden>

common clk framework, nxp i.mx clock drivers, the rest · Maintainers:

Keep the AHB clock always on since there is no driver to control it and all the other clocks that use it as parent rely on it being always enabled. Signed-off-by: Abel Vesa <redacted> Tested-by: Daniel Baluta <daniel.baluta@nxp.com> --- Changes since v1: * added comment in code why this clock is critical * added T-b by Daniel This needs to go in ASAP to fix the boot hang. drivers/clk/imx/clk-imx8mq.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
