clk: tegra: add Tegra specific clocks
Add Tegra specific clocks, pll, pll_out, peripheral, frac_divider, super.
Signed-off-by: Prashant Gaikwad <pgaikwad@nvidia.com>
[swarren: alloc sizeof(*foo) not sizeof(struct foo), add comments re:
storing pointers to stack variables, make a timeout loop more idiomatic,
use _clk_pll_disable() not clk_disable_pll() from _program_pll() to
avoid redundant lock operations, unified tegra_clk_periph() and
tegra_clk_periph_nodiv(), unified tegra_clk_pll{,e}, rename all clock
registration functions so they don't have the same name as the clock
structs, return -EINVAL from clk_plle_enable when matching table rate
not found, pass ops to _tegra_clk_register_pll rather than a bool.]
