Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.Signed-off-by: Stephen Boyd

Some qcom SoCs' can have hierarchical power domains. Let the gdsc structs
specify the parents (if any) and the driver add genpd subdomains for them.Signed-off-by: Rajendra Nayak

We were not checking the return from devm_add_action() which can fail.
Start using the helper and devm_add_action_or_reset() and return
directly as we know that the cleanup has been done by this helper.Signed-off-by: Sudip Mukherjee

We want to put the XO board clocks into the dt files, but we also
need to be backwards compatible with an older dtb. Add an API to
the common code to do this. This also makes a place for us to
handle the case when the RPM clock driver is enabled and we don't
want to register the fixed factor clock.Cc: Georgi Djakov

Now that qcom_cc_remove() is a nop, drop calls to
qcom_cc_remove() and any empty driver remove functions.Cc: Rajendra Nayak
Signed-off-by: Stephen Boyd -
Some APIs in qcom_cc_probe() don't have a devm counterpart, so we
have to use the calling device's platform data to pass pointers
to the remove path. Let's use devm_add_action() instead, so that
the remove path doesn't need to do anything, allowing us to
remove qcom_cc_remove() entirely.Cc: Rajendra Nayak

Certain devices can have GDSCs' which support ON as the only state.
They can't be power collapsed to either hit RET or OFF.
The clients drivers for these GDSCs' however would expect the state
of the core to be reset following a GDSC disable and re-enable.
To do this assert/deassert reset lines every time the client
driver would request the GDSC to be powered on/off instead.Signed-off-by: Rajendra Nayak

In the current parent mapping code, we can get duplicate or inconsistent
indexes, which leads to discrepancy between the number of elements in the
array and the number of parents. Until now, this was solved with some
reordering but this is not always possible.This patch introduces index tables that are used to define the relations
between the PLL source and the hardware mux configuration value.
To accomplish this, here we do the following:
- Define a parent_map struct to map the relations between PLL source index
and register configuration value.
- Add a qcom_find_src_index() function for finding the index of a clock
matching the specific PLL configuration.
- Update the {set,get}_parent RCG functions use the newly introduced
parent_map struct.
- Convert all existing drivers to the new parent_map tables.Signed-off-by: Georgi Djakov

There are two find_freq() functions in clk-rcg.c and clk-rcg2.c
that are almost exactly the same. Consolidate them into one
function to save on some code space.Cc: Mike Turquette

Sometimes we need to program PLLs with a fixed rate
configuration during driver probe. Doing this after we register
the PLLs with the clock framework causes the common clock
framework to assume the rate of the PLLs are 0. This causes all
sorts of problems for rate recalculations because the common
clock framework caches the rate once at registration time unless
a flag is set to always recalculate the rates.Split the qcom_cc_probe() function into two pieces, map and
everything else, so that drivers which need to configure some
PLL rates or otherwise twiddle bits in the clock controller can
do so before registering clocks. This allows us to properly
detect the rates of PLLs that are programmed at boot.Fixes: 49fc825f0cc2 "clk: qcom: Consolidate common probe code"

Not all clocks are implemented but client drivers can still
request them. Currently we will return a NULL pointer to them if
the clock isn't implemented in software but NULL pointers are
valid clock pointers. Return an error pointer so that driver's
don't proceed without a clock they may actually need.Signed-off-by: Stephen Boyd

Most of the probe code is the same between all the different
clock controllers. Consolidate the code into a common.c file.
This makes changes to the common probe parts easier and reduces
chances for bugs.Signed-off-by: Stephen Boyd
