Subject: [PATCH] ARM: shmobile: r8a7740: Add clocks to DTS
Date: Thu, 07 Aug 2014 08:12:10 +0000 [thread overview]
Message-ID: <1407399130-14020-1-git-send-email-ulrich.hecht+renesas@gmail.com> (raw)
Declares the r8a7740 clocks supported by the legacy clock framework,
excluding those requiring extensions to the DIV6 driver, as well as
the Armadillo800-specific overrides.
Signed-off-by: Ulrich Hecht <ulrich.hecht+renesas@gmail.com>

Hi!
This one omits the funky DIV6 clocks because the corresponding changes to
the clock driver have not been accepted yet. It should not have any
negative impact on legacy support.
