Subject: [PATCH] dt-bindings: media: i2c: Fix external clock frequency for OV5645
Date: Wed, 14 Nov 2018 16:09:35 +0530 [thread overview]
Message-ID: <20181114103935.24559-1-manivannan.sadhasivam@linaro.org> (raw)
Commit "4adb0a0432f4 media: ov5645: Supported external clock is 24MHz"
modified the external clock frequency to be 24MHz instead of the
23.88MHz in driver. Hence, make the same change in corresponding bindings
doc and mention the acceptable tolerance.
