Subject: [PATCH RESEND] ARM: mvebu: add clock aliases for spi0/spi1 on Dove
Date: Fri,  5 Jul 2013 23:21:45 +0200	[thread overview]
Message-ID: <1373059305-20443-1-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <20130705065137.GH516@pengutronix.de>

This adds clock aliases for spi controllers found on Dove to allow
spi driver to get tclk frequency.

Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

@Sascha: I forgot to update MVEBU SPI v4 patch numbering to indicate
that this patch is also required for the SPI driver to find its clock
with clk_get instead of clk_fixup.

As stated in the original patch for SPI clock aliases, I am not planing
to add any more clk aliases like this but prefer to work on DT clk
provider first.
