Purna Chandra Mandal a38c94106e clk: microchip: Initialize SOSC clock rate for PIC32MZDA.
Optional SOSC is an external fixed clock running at 32768HZ.
So Initialize SOSC rate as per PIC32MZDA datasheet.

Purna Chandra Mandal 12f53b2432 clk: microchip: use readl_poll_timeout() in pbclk_set_rate().
pbclk_set_rate() is using readl_poll_timeout_atomic() even
though spinlock is released. Fix it by replacing with
readl_poll_timeout().

Stephen Boyd 3c7f4f5457 clk: microchip: Remove CLK_IS_ROOT
This flag is a no-op now (see commit 47b0eeb3dc "clk: Deprecate
CLK_IS_ROOT", 2016-02-02) so remove it.

Purna Chandra Mandal ce6e118846 CLK: microchip: Add Microchip PIC32 clock driver.
This clock driver implements PIC32 specific clock-tree. clock-tree
entities can only be configured through device-tree file (OF).
