66b6da0cc6 clk: qcom: clk-alpha-pll: set ALPHA_EN bit for Stromer Plus PLLs
[ Upstream commit 5a33a64524e6381c399e5e42571d9363ffc0bed4 ]

The clk_alpha_pll_stromer_plus_set_rate() function does not
sets the ALPHA_EN bit in the USER_CTL register, so setting
rates which requires using alpha mode works only if the bit
gets set already prior calling the function.

Extend the function to set the ALPHA_EN bit in order to allow
using fractional rates regardless whether the bit gets set
previously or not.

0fcb94e0ee clk: qcom: gcc-sm6350: Fix gpll6* & gpll7 parents
[ Upstream commit 3414f41a13eb41db15c558fbc695466203dca4fa ]

Both gpll6 and gpll7 are parented to CXO at 19.2 MHz and not to GPLL0
which runs at 600 MHz. Also gpll6_out_even should have the parent gpll6
and not gpll0.

Adjust the parents of these clocks to make Linux report the correct rate
and not absurd numbers like gpll7 at ~25 GHz or gpll6 at 24 GHz.

Corrected rates are the following:

  gpll7              807999902 Hz
  gpll6              768000000 Hz
     gpll6_out_even  384000000 Hz
  gpll0              600000000 Hz
     gpll0_out_odd   200000000 Hz
     gpll0_out_even  300000000 Hz

And because gpll6 is the parent of gcc_sdcc2_apps_clk_src (at 202 MHz)
that clock also reports the correct rate now and avoids this warning:

  [    5.984062] mmc0: Card appears overclocked; req 202000000 Hz, actual 6312499237 Hz

ba02424852 clk: qcom: gcc-ipq9574: Add BRANCH_HALT_VOTED flag
commit 72ceafb587a56e26c905472418c7dc2033c294d3 upstream.

The crypto_ahb and crypto_axi clks are hardware voteable.
This means that the halt bit isn't reliable because some
other voter in the system, e.g. TrustZone, could be keeping
the clk enabled when the kernel turns it off from clk_disable().
Make these clks use voting mode by changing the halt check to
BRANCH_HALT_VOTED and toggle the voting bit in the voting register
instead of directly controlling the branch by writing to the branch
register. This fixes stuck clk warnings seen on ipq9574 and saves
power by actually turning the clk off.

Also changes the CRYPTO_AHB_CLK_ENA & CRYPTO_AXI_CLK_ENA
offset to 0xb004 from 0x16014.

a68c0c55fa clk: qcom: clk-alpha-pll: fix rate setting for Stromer PLLs
commit 3c5b3e17b8fd1f1add5a9477306c355fab126977 upstream.

The clk_alpha_pll_stromer_set_rate() function writes inproper
values into the ALPHA_VAL{,_U} registers which results in wrong
clock rates when the alpha value is used.

The broken behaviour can be seen on IPQ5018 for example, when
dynamic scaling sets the CPU frequency to 800000 KHz. In this
case the CPU cores are running only at 792031 KHz:

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
  800000
  # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
  792031

This happens because the function ignores the fact that the alpha
value calculated by the alpha_pll_round_rate() function is only
32 bits wide which must be extended to 40 bits if it is used on
a hardware which supports 40 bits wide values.

Extend the clk_alpha_pll_stromer_set_rate() function to convert
the alpha value to 40 bits before wrinting that into the registers
in order to ensure that the hardware really uses the requested rate.

After the change the CPU frequency is correct:

  # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
  800000
  # cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
  800000

63cbb3e704 clk: qcom: clk-alpha-pll: remove invalid Stromer register offset
[ Upstream commit 4f2bc4acbb1916b8cd2ce4bb3ba7b1cd7cb705fa ]

The offset of the CONFIG_CTL_U register defined for the Stromer
PLL is wrong. It is not aligned on a 4 bytes boundary which might
causes errors in regmap operations.

Maybe the intention behind of using the 0xff value was to indicate
that the register is not implemented in the PLL, but this is not
verified anywhere in the code. Moreover, this value is not used
even in other register offset arrays despite that those PLLs also
have unimplemented registers.

Additionally, on the Stromer PLLs the current code only touches
the CONFIG_CTL_U register if the result of pll_has_64bit_config()
is true which condition is not affected by the change.

Due to the reasons above, simply remove the CONFIG_CTL_U entry
from the Stromer specific array.

3ad0f41621 clk: qcom: gcc-ipq5018: fix 'halt_reg' offset of 'gcc_pcie1_pipe_clk'
[ 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_aux_clk            0x76014     0x76014
  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.

40c3768353 clk: qcom: gcc-ipq5018: fix 'enable_reg' offset of 'gcc_gmac0_sys_clk'
[ 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.

[ 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.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct spmi_pmic_div_clk_cc.
