[PATCH 0/2] Add R8A7790 CAN DT support

[PATCH 0/2] Add R8A7790 CAN DT support

[Sergei Shtylyov]

Hello.

   Here's the set of 2 patches against Simon Horman's 'renesas.git' repo,
'renesas-devel-20141229-v3.19-rc2' tag. Here we add the CAN device tree support
for the R8A7790 SoC (unfortunately, it's impossible to test CAN on the Lager
board). It depends on the clk driver RCAN clock patch posted recently in order
to work.

[PATCH 1/2] ARM: shmobile: r8a7790: add CAN clocks

[Sergei Shtylyov]

The R-Car CAN controllers can derive the CAN bus clock not only from their
peripheral clock input (clkp1) but also from the other internal clock (clkp2)
and external clock fed on CAN_CLK pin.  Describe those clocks in the device
tree,  along with  the USB_EXTAL clock  from which clkp2 is derived.
