Make sure to drop the reference taken when looking up the EMC device and
its driver data on first set_rate().
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference.

[ Upstream commit 5ec820fc28 ]
The 9FGV0841 has 8 outputs and registers 8 struct clk_hw, make sure
there are 8 slots for those newly registered clk_hw pointers, else
there is going to be out of bounds write when pointers 4..7 are set
into struct rs9_driver_data .clk_dif[4..7] field.
Since there are other structure members past this struct clk_hw
pointer array, writing to .clk_dif[4..7] fields corrupts both
the struct rs9_driver_data content and data around it, sometimes
without crashing the kernel. However, the kernel does surely
crash when the driver is unbound or during suspend.
Fix this, increase the struct clk_hw pointer array size to the
maximum output count of 9FGV0841, which is the biggest chip that
is supported by this driver.

[ Upstream commit 5df96d141c ]
roclk_get_parent() and sclk_get_parent() has the possibility of
returning -EINVAL, however the framework expects this call to always
succeed since the return value is unsigned.
If there is no parent map defined, then the current value programmed in
the hardware is used. Let's use that same value in the case where
-EINVAL is currently returned.
This index is only used by clk_core_get_parent_by_index(), and it
validates that it doesn't overflow the number of available parents.

All the MFGPLL require MFG_EB to be on for any operation on them, and
they only tick when MFG_EB is on as well, therefore making this a
parent-child relationship.
This dependency wasn't clear during the initial upstreaming of these
clock controllers, as it only made itself known when I could observe
the effects of the clock by bringing up a different piece of hardware.
Add a new PLL_PARENT_EN flag to mediatek's clk-pll.h, and check for it
when initialising the pll to then translate it into the actual
CLK_OPS_PARENT_ENABLE flag.
Then add the mfg_eb parent to the mfgpll clocks, and set the new
PLL_PARENT_EN flag.

[ Upstream commit d5639a6d72 ]
Use shared_floor_ops for the SDCC RCGs so the RCG is safely parked
during disable and the new parent configuration is programmed in
hardware only when the new parent is enabled, avoiding cases where
the RCG configuration fails to update.

[ Upstream commit 7aa6c24697 ]
GXBB has the HDMI PLL OD in the HHI_HDMI_PLL_CNTL2 register while for
G12A/G12B/SM1 the OD has moved to HHI_HDMI_PLL_CNTL0. At first glance
the rest of the OD setup seems identical.
However, looking at the downstream kernel sources as well as testing
shows that G12A/G12B/SM1 only supports three OD values:
- register value 0 means: divide by 1
- register value 1 means: divide by 2
- register value 2 means: divide by 4
Downstream sources are also only using OD register values 0, 1 and 2
for G12A/G12B/SM1 (while for GXBB the downstream kernel sources are also
using value 3 which means: divide by 8).
Add clk_div_table and have it replace the CLK_DIVIDER_POWER_OF_TWO flag
to make the kernel's view of this register match with how the hardware
actually works.

GXBB has the HDMI PLL OD in the HHI_HDMI_PLL_CNTL2 register while for
GXL/GXM the OD has moved to HHI_HDMI_PLL_CNTL3. At first glance the rest
of the OD setup seems identical.
However, looking at the downstream kernel sources as well as testing
shows that GXL only supports three OD values:
- register value 0 means: divide by 1
- register value 1 means: divide by 2
- register value 2 means: divide by 4
Using register value 3 (which on GXBB means: divide by 8) still divides
by 4 as verified using meson-clk-measure. Downstream sources are also
only using OD register values 0, 1 and 2 for GXL (while for GXBB the
downstream kernel sources are also using value 3).
Add clk_div_table and have it replace the CLK_DIVIDER_POWER_OF_TWO flag
to make the kernel's view of this register match with how the hardware
actually works.
