[ Upstream commit e2c02a85bf53ae86d79b5fccf0a75ac0b78e0c96 ]
The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

The current register offset used for the GCC_UBI0_AXI_ARES reset
seems wrong. Or at least, the downstream driver uses [1] the same
offset which is used for other the GCC_UBI0_*_ARES resets.
Change the code to use the same offset used in the downstream
driver and also specify the reset bit explicitly to use the
same format as the followup entries.

[ Upstream commit 11b752ac5a07cbfd95592fac5237a02f45662926 ]
The following table shows the values of the 'halt_reg' and the
'enable_reg' fields from the pcie clocks defined in the current
driver:
clock halt_reg enable_reg
gcc_pcie0_ahb_clk 0x75010 0x75010
gcc_pcie0_aux_clk 0x75014 0x75014
gcc_pcie0_axi_m_clk 0x75008 0x75008
gcc_pcie0_axi_s_bridge_clk 0x75048 0x75048
gcc_pcie0_axi_s_clk 0x7500c 0x7500c
gcc_pcie0_pipe_clk 0x75018 0x75018
gcc_pcie1_ahb_clk 0x76010 0x76010

gcc_pcie1_axi_m_clk 0x76008 0x76008
gcc_pcie1_axi_s_bridge_clk 0x76048 0x76048
gcc_pcie1_axi_s_clk 0x7600c 0x7600c
gcc_pcie1_pipe_clk 8* 0x76018
Based on the table, it is quite likely that the pcie0 and the pci1
clocks are using the same register layout, however it seems that
the value of the 'halt_reg' field in the 'gcc_pcie1_pipe_clk' clock
is wrong.
In the downstream driver [1], the same '0x76018' value is used for
both the 'halt_reg' and for the 'enable_reg' fields of the
'gcc_pcie1_pipe_clk' clock.
Update the current driver to use the same value used downstream as
probably that is the correct value.

[ Upstream commit f982adcc1b1c02a3114f68ac73c811cbfabe90fa ]
The value of the 'enable_reg' field in the 'gcc_gmac0_sys_clk'
clock definition seems wrong as it is greater than the
'max_register' value defined in the regmap configuration.
Additionally, all other gmac specific branch clock definitions
within the driver uses the same value both for the 'enable_reg'
and for the 'halt_reg' fields.
Due to the lack of documentation the correct value is not known.
Looking into the downstream driver does not help either, as that
uses the same (presumably wrong) value [1].
Nevertheless, change the 'enable_reg' field of 'gcc_gmac0_sys_clk'
to use the value from the 'halt_reg' field so it follows the pattern
used in other gmac clock definitions. The change is based on the
assumption that the register layout of this clock is the same
as the other gmac clocks.

[ Upstream commit 1fc62c8347397faf4e18249e88ecd4470c0a5357 ]
The SMMU GDSC doesn't have to be ALWAYS-ON and shouldn't feature the
HW_CTRL flag (it's separate from hw_ctrl_addr). In addition to that,
it should feature a cxc entry for bimc_smmu_axi_clk and be marked as
votable.
Fix all of these issues.

Some branch clocks are governed externally and we're only supposed to
send a request concerning their shutdown, not actually ensure it happens.

[ Upstream commit f7b7d30158cff246667273bd2a62fc93ee0725d2 ]
If the parent clock rate is greater than unsigned long max/2 then
integer overflow happens when calculating the clock rate on 32-bit systems.
As RCG2 uses half integer dividers, the clock rate is first being
multiplied by 2 which will overflow the unsigned long max value.
Hence, replace the common pattern of doing 64-bit multiplication
and then a do_div() call with simpler mult_frac call.

On all supported SoCs to date, the PCNoC (a.k.a CNoC_PERIPH) clock must
be always-on as long as the APSS is online and only has to run
at 19.2 MHz. Define it to be as such in the ACTIVE domain.
Some SoCs use that clock for bus scaling, while others just need it for
reaching the hardware. This commit will hurt neither.
