commit fff617979f97c773aaa9432c31cf62444b3bdbd4 upstream.
In LUCID EVO PLL CAL_L_VAL and L_VAL bitfields are part of single
PLL_L_VAL register. Update for L_VAL bitfield values in PLL_L_VAL
register using regmap_write() API in __alpha_pll_trion_set_rate
callback will override LUCID EVO PLL initial configuration related
to PLL_CAL_L_VAL bit fields in PLL_L_VAL register.
Observed random PLL lock failures during PLL enable due to such
override in PLL calibration value. Use regmap_update_bits() with
L_VAL bitfield mask instead of regmap_write() API to update only
PLL_L_VAL bitfields in __alpha_pll_trion_set_rate callback.

commit ade508b545c969c72cd68479f275a5dd640fd8b9 upstream.
With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This
can happen during scenarios such as system suspend and breaks the resume
of PCIe controllers from suspend.
So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs
during gdsc_disable() and allow the hardware to transition the GDSCs to
retention when the parent domain enters low power state during system
suspend.

commit 12fd64babaca4dc09d072f63eda76ba44119816a upstream.
There is a clk == NULL check after the switch to check for
unsupported clk types. Since clk is re-assigned in a loop,
this check is useless right now for anything but the first
round. Let's fix this up by assigning clk = NULL in the
loop before the switch statement.

[ Upstream commit 3d29036853b9cb07ac49e8261fca82a940be5c41 ]
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 commit 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:
clk_set_parent(dram_apb_src, sys1_pll_40m);(busfreq-imx8mq.c)
commit 926bf91248dd
("clk: imx8m: fix clock tree update of TF-A managed clocks") adds this
method and enables 8mm, 8mn and 8mq. i.MX8MP also needs it.
This is safe to do, because updating the Linux clock tree to reflect
reality will always be glitch-free.
Another reason to this patch is that powersave image BT music
requires dram to be 400MTS, so clk_set_parent(dram_alt_src,
sys1_pll_800m); is required. Without this patch, it will not succeed.

display CCM ROOT disabled by Bootloader, kernel display BLK CTRL driver
imx8m_blk_ctrl_driver_init may hang the system because the BUS clk is
disabled.
Add back gate ops, but with disable doing nothing, then the CCM ROOT

[ Upstream commit e52fd71333b4ed78fd5bb43094bdc46476614d25 ]
The clk_set_parent for "enet1_ref_sel" and "enet2_ref_sel" are
incorrect, therefore the original requirements to have "enet_clk_ref" as
output sourced by iMX ENET PLL as a default config is not met.
Only "enet[1,2]_ref_125m" "enet[1,2]_ref_pad" are possible parents for
"enet1_ref_sel" and "enet2_ref_sel".
This was observed as a regression using a custom device tree which was
expecting this default config.
This can be fixed at the device tree level but having a default config
matching the original behavior (before refclock mux) will avoid breaking
existing configs.

[ Upstream commit d10eeb75168b84ed9559c58efe2756c2e0bc052a ]
The QUPs aren't shared in a way that requires parking the RCG at an
always on parent in case some other entity turns on the clk. The
hardware is capable of setting a new frequency itself with the DFS mode,
so parking is unnecessary. Furthermore, there aren't any GDSCs for these
devices, so there isn't a possibility of the GDSC turning on the clks
for housekeeping purposes.
This wasn't a problem to mark these clks shared until we started parking
shared RCGs at clk registration time in commit 01a0a6cc8cfd ("clk: qcom:
Park shared RCGs upon registration"). Parking at init is actually
harmful to the UART when earlycon is used. If the device is pumping out
data while the frequency changes you'll see garbage on the serial
console until the driver can probe and actually set a proper frequency.
Revert the QUP part of commit 929c75d57566 ("clk: qcom: gcc-sm8550: Mark
RCGs shared where applicable") so that the QUPs don't get parked during
clk registration and break UART operations.

[ Upstream commit 6357efe3abead68048729adf11a9363881657939 ]
Update PLL offsets to DEFAULT_EVO to configure MDIO to 800MHz.
The incorrect clock frequency leads to an incorrect MDIO clock. This,
in turn, affects the MDIO hardware configurations as the divider is
calculated from the MDIO clock frequency. If the clock frequency is
not as expected, the MDIO register fails due to the generation of an
incorrect MDIO frequency.
This issue is critical as it results in incorrect MDIO configurations
and ultimately leads to the MDIO function not working. This results in
a complete feature failure affecting all Ethernet PHYs. Specifically,
Ethernet will not work on IPQ9574 due to this issue.
Currently, the clock frequency is set to CLK_ALPHA_PLL_TYPE_DEFAULT.
However, this setting does not yield the expected clock frequency.
To rectify this, we need to change this to CLK_ALPHA_PLL_TYPE_DEFAULT_EVO.
This modification ensures that the clock frequency aligns with our
expectations, thereby resolving the MDIO register failure and ensuring
the proper functioning of the Ethernet on IPQ9574.

[ Upstream commit 397d887c1601a71e8a8abdb6beea67d58f0472d3 ]
In order to gain the bounds-checking coverage that __counted_by provides
to flexible-array members at run-time via CONFIG_UBSAN_BOUNDS (for array
indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions),
we must make sure that the counter member, in this particular case `num`,
is updated before the first access to the flex-array member, in this
particular case array `hws`. See below:
commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with
__counted_by") introduced `__counted_by` for `struct clk_hw_onecell_data`
together with changes to relocate some of assignments of counter `num`
before `hws` is accessed:
include/linux/clk-provider.h:
1380 struct clk_hw_onecell_data {
1381 unsigned int num;
1382 struct clk_hw *hws[] __counted_by(num);
1383 };
However, this structure is used as a member in other structs, in this
case in `struct visconti_pll_provider`:
drivers/clk/visconti/pll.h:
16 struct visconti_pll_provider {
17 void __iomem *reg_base;
18 struct device_node *node;
19
20 /* Must be last */
21 struct clk_hw_onecell_data clk_data;
22 };
Hence, we need to move the assignments to `ctx->clk_data.num` after
allocation for `struct visconti_pll_provider` and before accessing the
flexible array `ctx->clk_data.hws`. And, as assignments for all members
in `struct visconti_pll_provider` are originally adjacent to each other,
relocate all assignments together, so we don't split up
`ctx->clk_data.hws = nr_plls` from the rest. :)

[ Upstream commit 01a0a6cc8cfd9952e72677d48d56cf6bc4e3a561 ]
There's two problems with shared RCGs.
The first problem is that they incorrectly report the parent after
commit 703db1f5da1e ("clk: qcom: rcg2: Cache CFG register updates for
parked RCGs"). That's because the cached CFG register value needs to be
populated when the clk is registered. clk_rcg2_shared_enable() writes
the cached CFG register value 'parked_cfg'. This value is initially zero
due to static initializers. If a driver calls clk_enable() before
setting a rate or parent, it will set the parent to '0' which is
(almost?) always XO, and may not reflect the parent at registration. In
the worst case, this switches the RCG from sourcing a fast PLL to the
slow crystal speed.
The second problem is that the force enable bit isn't cleared. The force
enable bit is only used during parking and unparking of shared RCGs.
Otherwise it shouldn't be set because it keeps the RCG enabled even when
all the branches on the output of the RCG are disabled (the hardware has
a feedback mechanism so that any child branches keep the RCG enabled
when the branch enable bit is set). This problem wastes power if the clk
is unused, and is harmful in the case that the clk framework disables
the parent of the force enabled RCG. In the latter case, the GDSC the
shared RCG is associated with will get wedged if the RCG's source clk is
disabled and the GDSC tries to enable the RCG to do "housekeeping" while
powering on.
Both of these problems combined with incorrect runtime PM usage in the
display driver lead to a black screen on Qualcomm sc7180 Trogdor
chromebooks. What happens is that the bootloader leaves the
'disp_cc_mdss_rot_clk' enabled and the 'disp_cc_mdss_rot_clk_src' force
enabled and parented to 'disp_cc_pll0'. The mdss driver probes and
runtime suspends, disabling the mdss_gdsc which uses the
'disp_cc_mdss_rot_clk_src' for "housekeeping". The
'disp_cc_mdss_rot_clk' is disabled during late init because the clk is
unused, but the parent 'disp_cc_mdss_rot_clk_src' is still force enabled
because the force enable bit was never cleared. Then 'disp_cc_pll0' is
disabled because it is also unused. That's because the clk framework
believes the parent of the RCG is XO when it isn't. A child device of
the mdss device (e.g. DSI) runtime resumes mdss which powers on the
mdss_gdsc. This wedges the GDSC because 'disp_cc_mdss_rot_clk_src' is
parented to 'disp_cc_pll0' and that PLL is off. With the GDSC wedged,
mdss_runtime_resume() tries to enable 'disp_cc_mdss_mdp_clk' but it
can't because the GDSC has wedged all the clks associated with the GDSC
causing clks to stay stuck off.
This leads to the following warning seen at boot and a black screen
because the display driver fails to probe.

[ Upstream commit dff68b2f74547617dbb75d0d12f404877ec8f8ce ]
The RCG's clk src has to be parked at XO while disabling as per the
HW recommendation, hence use clk_rcg2_shared_ops to achieve the same.
Also gpu_cc_cb_clk is recommended to be kept always ON, hence use
clk_branch2_aon_ops to keep the clock always ON.

[ Upstream commit e69386d4a42afa5da6bfdcd4ac5ec61e1db04c61 ]
The GPU clocks/GDSCs have been marked critical from the clock driver
but the GPU driver votes on these resources as per the HW requirement.
In the case where these clocks & GDSCs are left enabled, would have
power impact and also cause GPU stability/corruptions.
Fix the same by removing the CLK_IS_CRITICAL for clocks and ALWAYS_ON
flags for the GPU GDSCs.

[ Upstream commit be208c0ccf7d861fc6109ca06c1a773512739af9 ]
Update the GDSC wait_val fields as per the default hardware values as
otherwise they would lead to GDSC FSM state to be stuck and causing
failures to power on/off. Also add the GDSC flags as applicable and
add support to control PCIE GDSC's using collapse vote registers.

[ Upstream commit 63aec3e4d987fd43237f557460345bca3b51e530 ]
Camera titan top GDSC is a parent supply to all other camera GDSCs. Titan
top GDSC is required to be enabled before enabling any other camera GDSCs
and it should be disabled only after all other camera GDSCs are disabled.
Ensure this behavior by marking titan top GDSC as parent of all other
camera GDSCs.

[ Upstream commit 878e845d8db04df9ff3bbbaac09d335b24153704 ]
Commit 2f7b1d8b5505 ("clk: mediatek: Do a runtime PM get on controllers
during probe") enabled runtime PM for all mediatek clock controllers,
but this introduced an issue on the resume path.
If a device resumes earlier than the clock controller and calls
clk_prepare() when runtime PM is enabled on the controller, it will end
up calling clk_pm_runtime_get(). But the subsequent
pm_runtime_resume_and_get() call will fail because the runtime PM is
temporarily disabled during suspend.
To workaround this, introduce a need_runtime_pm flag and only enable it
on mt8183-mfgcfg, which is the driver that observed deadlock previously.
Hopefully mt8183-cfgcfg won't run into the issue at the resume stage
because the GPU should have stopped rendering before the system calls
suspend.
