Peter De Schrijver - Feb. 1, 2013, 10:18 a.m.
Refactor the PLL programming code to make it useable by the new PLL types
introduced by Tegra114.

The following changes were done:

* Split programming the PLL into updating m,n,p and updating cpcon
* Move locking from _update_pll_cpcon() to clk_pll_set_rate()
* Introduce _get_pll_mnp() helper
* Move check for identical m,n,p values to clk_pll_set_rate()
* struct tegra_clk_pll_freq_table will always contain the values as defined
  by the hardware.
* Simplify the arguments to clk_pll_wait_for_lock()

This will not work for PLLE. Lock bit for PLLE is in misc register.

Need to change the lock bit idx parameter for Tegra20 and Tegra30 PLLs 
else this patch will break those.

Looking at commit 37c26a906527b8a6a252614ca83d21ad318c4e84 and commit
b08e8c0ecc42afa3a2e1019851af741980dd5a6b, these fields seem correctly
initialized for both Tegra20 and Tegra30? Or am I missing something?

Thanks,

Peter.

I tested this series on Tegra20 and Tegra30 for regressions and found
none. Note that I didn't test on Tegra114. The series,

Also, I briefly reviewed the code and aside from comments that have
already been made, so the series,
