From mboxrd@z Thu Jan 1 00:00:00 1970 From: festevam@gmail.com (Fabio Estevam) Date: Mon, 6 Oct 2014 21:37:42 -0300 Subject: [PATCH] ARM: dts: imx28-evk: Let i2c0 run at 100kHz Message-ID: <1412642262-18020-1-git-send-email-festevam@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Fabio Estevam 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.
