Subject: [PATCH v2 1/4] net: macb: enable GEM with only FE feature
Date: Tue, 23 Sep 2014 16:29:15 +0800 [thread overview]
Message-ID: <1411460958-27491-2-git-send-email-voice.shen@atmel.com> (raw)
In-Reply-To: <1411460958-27491-1-git-send-email-voice.shen@atmel.com>
If the GEM is used, however only FE featuren enabled, then it can not
support FBLDO configured as 16, and no RGMII/GMII configuratin bit.
So, in order to support GEM only with FE feature enabled, we do:
- using default value for FBLDO.
- using same bit for RMII/MII configuration as GEM for RGMII/GMII.
Signed-off-by: Bo Shen <voice.shen@atmel.com>

Changes in v2:
- using the same bit for RMII/MII configuration for GEM only with FE feature.
