Subject: [U-Boot] [PATCH] ARM: OMAP5: DRA7xx: Enable I2C4 and I2C5 usage on the J6Eco EVM
Date: Thu, 18 Dec 2014 13:00:34 +0200	[thread overview]
Message-ID: <5492B3D2.9050107@mm-sol.com> (raw)
In-Reply-To: <20141117134005.GR21184@bill-the-cat>

Tom,

Even if this patch is not applied if considered useless, the one fixing
the clocks (http://patchwork.ozlabs.org/patch/410834/) should be, in my
opinion, as it is essentially a bug fix. Now, for the DRA7xx SoCs,
1) a write to a undefined (or zero) register address is occurring since
   struct member .cm_l4per_i2c5_clkctrl is not initialized, and
2) a 'data abort' exception shall happen if access to I2C5 is tried due
   to lack of the functional clock.

Best regards,
Lubo
