Implement clock support for Tegra124.
Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>

|
Introduce a common function which performs super clock initialization for
Tegra114 and beyond.

Introduce new files for fixed and PMC clocks common between several Tegra
SoCs and move Tegra114 to this new infrastructure.

Introduce a new file for peripheral clocks common between several Tegra
SoCs and move Tegra114 to this new infrastructure. Also PLLP and the PLLP_OUT
clocks will be initialized here.

Move audio clocks and PLLA initialization to a common file so it can be used by
multiple Tegra SoCs. Also a new array tegra114_clks is introduced for Tegra114
which specifies which common clocks are available on Tegra114 and what their
DT IDs are.

Add Tegra30 clock support based on common clock framework.
Signed-off-by: Prashant Gaikwad <pgaikwad@nvidia.com>
[swarren: ensure all OF lookups return valid cookies i.e. an explicit
error pointer or valid pointer not NULL, adapt to renames in earlier
patches, fixed some checkpatch issues.]

Add Tegra20 clock support based on common clock framework.

[swarren: s/1GHz/100MHz/ in call to tegra_clk_plle() to fix PCIe,
implemented KBC clock, ensure all OF lookups return valid cookies i.e.
an explicit error pointer or valid pointer not NULL, adapt to renames
in earlier patches, fixed some checkpatch issues.]

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.]
