_probe function and to call pm_runtime_disable() both from _probe error
path and from _remove function. For some drivers the whole remove

clk: imx8m: fix clock tree update of TF-A managed clocks

On the i.MX8M*, the TF-A exposes a SiP (Silicon Provider) service
for DDR frequency scaling. The imx8m-ddrc-devfreq driver calls the
SiP and then does clk_set_parent on the DDR muxes to synchronize
the clock tree.

Since 936c383673b9 ("clk: imx: fix composite peripheral flags"),
these TF-A managed muxes have SET_PARENT_GATE set, which results
in imx8m-ddrc-devfreq's clk_set_parent after SiP failing with -EBUSY:

echo 25000000 > userspace/set_freq
imx8m-ddrc-devfreq 3d400000.memory-controller: failed to set
dram_apb parent: -16

Fix this by adding a new i.MX composite flag for firmware managed
clocks, which clears SET_PARENT_GATE.

This is safe to do, because updating the Linux clock tree to reflect
reality will always be glitch-free.

.determine_rate is meant to replace .round_rate. The former comes with a
benefit which is especially relevant on 32-bit systems: since
.determine_rate uses an "unsigned long" (compared to a "signed long"

increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).

Implement .determine_rate in addition to .round_rate so drivers that are
using clk_divider_{ro_,}ops can benefit from this by default. Keep the

clk: rockchip: make rk3308 ddrphy4x clock critical

Currently, no driver support for DDR memory controller (DMC) is present,
as a result, no driver is explicitly consuming the ddrphy clock. This means
that VPLL1 (parent of ddr clock) will be shutdown if we enable
and then disable any child clock of VPLL1 (e.g. SCLK_I2S0_8CH_TX).
If VPLL1 is disabled, the whole system will freeze, because the DDR
controller will lose its clock. So, it's necessary to prevent VPLL1 from
shutting down, by marking the ddrphy4x CLK_IS_CRITICAL.

This bug was discovered when I was porting rockchip_i2s_tdm driver to
mainline kernel from Rockchip 4.4 kernel. I guess that other Rockchip
SoCs without DMC driver may need the same patch. If this applies to

clk: rockchip: drop GRF dependency for rk3328/rk3036 pll types

The rk3036/rk3328 pll types were converted to checking the lock status
via the internal register in january 2020, so don't need the grf
reference since then.

But it was forgotten to remove grf check when deciding between the
pll rate ops (read-only vs. read-write), so a clock driver without
the needed grf reference might've been put into the read-only mode
just because the grf reference was missing.

This affected the rk356x that needs to reclock certain plls at boot.

Fix this by removing the check for the grf for selecting the utilized
operations.
