Subject: ARM: dts: imx28-evk: Let i2c0 run at 100kHz
From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>
commit d1e61eb443dc7512885dfe89ee2f2a1c29fcb1da upstream.
Commit 78b81f4666fb ("ARM: dts: imx28-evk: Run I2C0 at 400kHz") caused issues
when doing the following sequence in loop:
- Boot the kernel
- Perform audio playback
- Reboot the system via 'reboot' command
In many times the audio card cannot be probed, which causes playback to fail.
After restoring to the original i2c0 frequency of 100kHz there is no such
problem anymore.
This reverts commit 78b81f4666fbb22a20b1e63e5baf197ad2e90e88.
