Prashant Gaikwad - Jan. 11, 2013, 8:01 a.m.
Since Tegra spi devices do not have multiple clocks, no need to use
clock name to get the clock.

Signed-off-by: Prashant Gaikwad <pgaikwad@nvidia.com>

This series depends on v4 of Tegra's ccf-rework patch series.
Tested on Ventana (Tegra20) and Cardhu (Tegra30).
Rebased on Tegra's for-3.9/soc and for-3.9/cleanup.

Changes from V1:
- Fixed clock lookup for SPI and nvec drivers.
- Add clock information for nvec in device tree.

Cc'ing in the SPI maintainers as an FYI and for Acks; this patch needs
to go through the Tegra tree due to dependencies.

No problem merging it via the Tegra tree.
