Tero Kristo b6f5128459 clk: ti: dpll: convert DPLL support code to use clk_hw instead of clk ptrs
Convert DPLL support code to use clk_hw pointers for reference and bypass
clocks. This allows us to use clk_hw_* APIs for accessing any required
parameters for these clocks, avoiding some locking problems at least with
DPLL enable code; this used clk_get_rate which uses mutex but isn't
good under clk_enable / clk_disable.

Julia Lawall d687767a91 clk: ti: dra7: constify clk_hw_omap_ops structure
The clk_hw_omap_ops structures are never modified, so declare this one as
const, like the others.

Done with the help of Coccinelle.

Stephen Boyd 836ee0f7d9 clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)
Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.

@@
struct clk_hw *E;
@@

-__clk_get_name(E->clk)
+clk_hw_get_name(E)

Tero Kristo a3314e9cf6 clk: ti: move some public definitions to private header
Several exported TI clock driver features are no longer needed outside
the clock driver itself, thus move all of these to the driver private
header file. Also, update some of the driver files to actually include
this header.

Tero Kristo c807dbedb5 clk: ti: fix ti_clk_get_reg_addr error handling
There is a case where NULL can be a valid return value for
ti_clk_get_reg_addr, specifically the case where both the provider index
and register offsets are zero. In this case, the current error checking
against a NULL pointer will fail. Thus, change the API to return a
ERR_PTR value in an error case, and change all the users of this API to
check against IS_ERR instead.

Add a returned error code in the MAX_APLL_WAIT_TRIES case.  Remove the
updating of the return variable r to 0 if MAX_APLL_WAIT_TRIES is not yet
reached, because r is already 0 at this point.

J Keerthy 3cf467a996 CLK: TI: DRA7: Add APLL support
The patch adds support for DRA7 PCIe APLL. The APLL
sources the optional functional clocks for PCIe module.

APLL stands for Analog PLL. This is different when comapred
with DPLL meaning Digital PLL, the phase detection is done
using an analog circuit.
