1a500e0bc9 clk: qcom: gcc-sm8350: fix PCIe PIPE clocks handling
On SM8350 platform the PCIe PIPE clocks require additional handling to
function correctly. They are to be switched to the tcxo source before
turning PCIe GDSCs off and should be switched to PHY PIPE source once
they are working. Switch PCIe PHY clocks to use clk_regmap_phy_mux_ops,
which provide support for this dance.

The USB controller on msm8998 doesn't retain its state when the system
goes into low power state and the GDSCs are turned off.

This can be observed by the USB connection not coming back alive after
putting the device into suspend, essentially breaking USB.

Work around this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.

This change should be reverted when a proper suspend sequence is
implemented in the USB drivers.

0932e565ba clk: qcom: branch: Add helper functions for setting SLEEP/WAKE bits
HLOS-controlled branch clocks on non-ancient Qualcomm platforms
feature SLEEP and WAKE fields which can be written to to configure
how long the clock hardware should wait internally before being
(un)gated. Some very sensitive clocks need to have these values
programmed to prevent putting the hardware in a not-exactly-good
state. Add definitions of these fields and introduce helpers for
setting them inside clock drivers.

Most Qualcomm branch clocks come with a pretty usual set of bits that
can enable memory retention by means of not turning off parts of the
memory logic. Add them to the common header file and introduce helper

c4dc24da52 clk: qcom: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

0277263659 clk: qcom: add the driver for the MSM8996 APCS clocks
Add a simple driver handling the APCS clocks on MSM8996. For now it
supports just a single aux clock, linking GPLL0 to CPU and CBF clocks.

Note, there is little sense in registering sys_apcs_aux as a child of
gpll0. The PLL is always-on. And listing the gpll0 as a property of the
apcs would delay its probing until the GCC has been probed (while we
would like for the apcs to be probed as early as possible).
