clk: mmp: add timer clock for pxa168/mmp2/pxa910

2015-06-04T19:07:53+00:00

Timer has external fast clock, and it is a mux clock.
Add the timer clock type for timer driver.

clk: mmp: Fix the wrong factor table for uart PLL

2015-06-04T19:07:49+00:00

The suggested value in the mmp2 manual is wrong.
There are only 13 bits for numerator, but some suggested
value has 14 bits.
Fix the factor tabled and remove the unused items.

clk: mmp: add PXA1928 clock support

2015-05-15T19:31:45+00:00

Add initial clock support for Marvell PXA1928. The PXA1928 is a mobile
SOC and is similar to other MMP/PXA series of SOCs, so a lot of the
existing infrastructure is reused here.

Currently the PLLs are just fixed clocks, and not all leaf clocks are
implemented.

clk: Add rate constraints to clocks

2015-02-02T22:23:42+00:00

Adds a way for clock consumers to set maximum and minimum rates. This
can be used for thermal drivers to set minimum rates, or by misc.
drivers to set maximum rates to assure a minimum performance level.

Changes the signature of the determine_rate callback by adding the
parameters min_rate and max_rate.

This is in preparation for clock providers to not have to deal with struct clk.
