Subject: [PATCH] ARM: shmobile: r8a7790: add ADSP clocks

From: [email-masked] (Sergei Shtylyov)
Date: Tue, 30 Dec 2014 23:21:45 +0300

Add the ADSP clocks to the CPG and MSTP5 nodes of the R8A7790 device tree.

Based on the original patch by Konstantin Kozhevnikov
<[email-masked]>.

Signed-off-by: Sergei Shtylyov <[email-masked]>

---
The patch is against 'renesas-devel-20141229-v3.19-rc2' tag of Simon Horman's
'renesas.git' repo plus the R8A7790 CAN patches posted earlier. It depends on
the patch adding the ADSP clock support to the 'clk-rcar-gen2' driver in order
to work.
