Subject: [PATCH v3 0/2] ARM: OMAP4+: Fix gpmc_fck clock
Date: Wed, 26 Feb 2014 11:38:07 +0100 [thread overview]
Message-ID: <1393411089-9550-1-git-send-email-florian.vaussard@epfl.ch> (raw)
Hello,
Trying to get my SMSC9221 working on OMAP4 with DT,
I faced a misconfigured gpmc_fck (dummy clock set to 0)
resulting in serveral division-by-zero, misconfigured
timings and driver lost in the La La Land.
To solve this, patch 1 removes gpmc_fck from the dummy
clocks, and patch 2 adds the gpmc_fck DT node and
reference it from the gpmc node.
*Note*: For DRA7, there is no DTS node for the GPMC, so I
was unable to set the corresponding clock. And without
a public TRM, I cannot do much more.
Tested on DuoVero/Parlor (OMAP4430) with SMSC9221 (DTS
was posted on the OMAP ML [1]).
Regards,
Florian

Since v2:
- Added OMAP5 and DRA7
Since v1:
- Removed the gpmc_fck clock node, and reference directly l3_ick
