The Global Clock Controller (GCC) in the MSM8909 SoC provides clocks,
resets and power domains for the various hardware blocks in the SoC.
Add a driver for it to make it possible to enable additional
functionality for the SoC.
Work on this driver was originally started independently by Dominik,
I picked it up and added missing clocks/resets, as well as various
cleanup to bring it into shape for mainline.

Split and extend existing CLK_AIF_OSR_DIV macro to implement mi2s
clocks. This simplifies the driver and removes extra code duplication.
The clock mi2s_div_clk used .enable_reg/.enable_bit, however these
fields are not used with by the clk_regmap_div_ops, thus they are
silently dropped. Clock enablement is handled in the mi2s_bit_div_clk

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and
adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while
also removing some GDSCs. Despite these differences, there are many
similarities with SDM670. Add data for SDM670 in the driver for SDM845 to
reuse the most of the clock data.
Advantages and disadvantages of this approach:
+ maintenance applies to both sdm670 and sdm845 by default
+ less duplicate code (clocks) means smaller distro/pre-built kernels
with all drivers enabled
- clocks for both SoC's must be compiled if the user wants clocks for one
specific SoC (both or none)
- additional testing needed for sdm845 devices

The enet_qos_root_clk takes sim_enet_root_clk as parent. When
registering enet_qos_root_clk, it will be put into clk orphan list,
because sim_enet_root_clk is not ready.
When sim_enet_root_clk is ready, clk_core_reparent_orphans_nolock will
set enet_qos_root_clk parent to sim_enet_root_clk.
Because CLK_OPS_PARENT_ENABLE is set, sim_enet_root_clk will be
enabled and disabled during the enet_qos_root_clk reparent phase.
All the above are correct. But with M7 booted early and using
enet, M7 enet feature will be broken, because clk driver probe phase
disable the needed clks, in case M7 firmware not configure
sim_enet_root_clk.
And tune the order would also save cpu cycles.

For this reason, turning off the pwrmcu related clocks from the kernel

The function zynqmp_pll_round_rate is used to find a most appropriate
PLL frequency which the hardware can generate according to the desired
frequency. For example, if the desired frequency is 297MHz, considering
the limited range from PS_PLL_VCO_MIN (1.5GHz) to PS_PLL_VCO_MAX (3.0GHz)
of PLL, zynqmp_pll_round_rate should return 1.872GHz (297MHz * 5).
There are two problems with the current code of zynqmp_pll_round_rate:
1) When the rate is below PS_PLL_VCO_MIN, it can't find a correct rate
when the parameter "rate" is an integer multiple of *prate, in other words,
if "f" is zero, zynqmp_pll_round_rate won't return a valid frequency which
is from PS_PLL_VCO_MIN to PS_PLL_VCO_MAX. For example, *prate is 33MHz
and the rate is 660MHz, zynqmp_pll_round_rate will not boost up rate and
just return 660MHz, and this will cause clk_calc_new_rates failure since
zynqmp_pll_round_rate returns an invalid rate out of its boundaries.
2) Even if the rate is higher than PS_PLL_VCO_MIN, there is still a risk
that zynqmp_pll_round_rate returns an invalid rate because the function
DIV_ROUND_CLOSEST makes some loss in the fractional part. If the parent
clock *prate is 33333333Hz and we want to set the PLL rate to 1.5GHz,
this function will return 1499999985Hz by using the formula below:
value = *prate * DIV_ROUND_CLOSEST(rate, *prate)).
This value is also invalid since it's slightly smaller than PS_PLL_VCO_MIN.
because DIV_ROUND_CLOSEST makes some loss in the fractional part.

Rather than defining (incorrect) global clocks and clock-names lists,
define them per platform using conditionals. Also, while we are at it,
mark these properties as required for all platforms for which DT files
contained clocks/clock-names for the MMCC nodes from the beginning (in
addition to existing MSM8998 this adds MSM8994, SDM630 and SDM660).

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names. Use parent_hws where possible to refer parent
clocks directly, skipping the lookup.

The gcc_mss_q6_bimc_axi_clk clock depends on the bimc_ddr_clk_src clock.
Move it down in the file to come after the source clock.

Move GPLL definitions up, before the clock parent tables, so that we can
use gpll hw clock fields in the parent_data/parent_hws tables.

Use ARRAY_SIZE() instead of manually specifying num_parents. This makes
adding/removing entries to/from parent_data easy and errorproof.
This conversion fixes an issue present since the first version of this
driver. For the gp1_clk_src, gp2_clk_src and gp3_clk_src it was
impossible to select sleep_clk as a prent of the clock, since
num_parents was limited to 3 rather than 4. Switching to use num_parents
automatically makes sleep_clk available for selection.
