This contains the EMC clock driver that's been exhaustively reviewed and tested. It also includes a change to the clock core that allows a clock provider to perform low-level reparenting of clocks. This is required by the EMC clock driver because the reparenting needs to be done at a very specific point in time during the EMC frequency switch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVU1EDAAoJEN0jrNd/PrOhYO8QAKDSJXdoVqtQITU3lUDfTB7i g7EJfL8PjT5i1KTjJHT7/2FFuQlb7eeJexyNV539sIJtUrcDOl6qNVbq/FYNouia bF7XqOxbR8QpWsYbQ46bzbwBaDd+CPLDwjSounNf6G4kJQy7/9SVr6BBPbLa2LIS xzxMzr2+/CCmH9P1p2I5ey5f1fQ75DKaz8RGgv3FcltdkKNZQCTa+hthCOdicNJu BoVHqXgJZvz0tgZk0zdCrKyUi31Gu8CNmFad7jtIS01EHGjBpgSE9m7ViYYRCFl5 GIjVh5IryCg2LJt8JP2mPCFNyiAvjxzMt/hJquzj2x2QMKrK8wgC3BwlrMUPuhkM xkldCMXY1ImVgTbwFdAEFR08+/VybzfLu4FDZSdG4IeNKfMj0n3EirAX9gE1VHDl bofkPZsE2Vr4N3jYekjbql3m9ZO8WsnIRz7D/Rd1OIqNyMA3xZQz79zgqQ5EQsB1 +GJztoyIdDikefCAww/z7I+vTTQ8InV/FnuzKN/SyqqLe5Ni9TFg6sCN50cnW2Ps /wHE0KAEV6Oem0dNOISCd3cx231FAiCKQBSm0sUl0cAQ+x1E/NKs6H7vC0wrvWOo f7072+BesVG9FPpWUg/lAD95YlPcoFdTDUep9J6mX2RB5ZfVEr9gNN04dY3tt4g2 kl37UB2qRXX0aEdkTWm2 =I0gO -----END PGP SIGNATURE----- Merge tag 'tegra-for-4.2-clk' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into clk-next clk: tegra: Changes for v4.2-rc1 This contains the EMC clock driver that's been exhaustively reviewed and tested.

The common clock framework is a single definition of struct
|

clk, useful across many platforms, as well as an
|
|
implementation of the clock API in include/linux/clk.h.
|
|
Architectures utilizing the common struct clk should select

This driver supports the TI CDCE925 programmable clock synthesizer.
|
|
The chip contains two PLLs with spread-spectrum clocking support and
|
|
five output dividers. The driver only supports the following setup,
|
|
and uses a fixed setting for the output muxes.
|
|
Y1 is derived from the input clock
|
|
Y2 and Y3 derive from PLL1
|
|
Y4 and Y5 derive from PLL2
|
|
Given a target output frequency, the driver will set the PLL and
|
|
divider to best approximate the desired output.
