I.MX7S CCM Clko1 Clock gating from kernel space

akashgajjar — Tue, 07 Mar 2017 09:09:51 GMT

Hi All,

On my i.MX7S board I have configured GPIO1 [02] as Clko1 for feeding clock to the slave device.

At run time from Linux kernel space I need to gate the clock so that can reduce the power consumption.

Is there any mechanism to do that by using sysfs or register level Operation?

Best Regards,

Akash Gajjar

Hi Akash

one can change register value using memtool in unit tests (folder memtool)
