The register offset array defined locally for the
CLK_ALPHA_PLL_TYPE_STROMER_PLUS is the same as the
entry defined for CLK_ALPHA_PLL_TYPE_STROMER in the
'clk_alpha_pll_regs' array.
To avoid code duplication, remove the local definition
and use the global one instead.
No functional changes.

'20240315-apss-ipq-pll-ipq5018-hang-v2-1-6fe30ada2009@gmail.com' into clk-for-6.10
Merge IPQ5018 boot failure fix from topic branch, in order to be able to
add subsequent cleanup patches on top, for v6.10.
|
|
Booting v6.8 results in a hang on various IPQ5018 based boards.
Investigating the problem showed that the hang happens when the
clk_alpha_pll_stromer_plus_set_rate() function tries to write
into the PLL_MODE register of the APSS PLL.
Checking the downstream code revealed that it uses [1] stromer
specific operations for IPQ5018, whereas in the current code
the stromer plus specific operations are used.
The ops in the 'ipq_pll_stromer_plus' clock definition can't be
changed since that is needed for IPQ5332, so add a new alpha pll
clock declaration which uses the correct stromer ops and use this
new clock for IPQ5018 to avoid the boot failure.
Also, change pll_type in 'ipq5018_pll_data' to
CLK_ALPHA_PLL_TYPE_STROMER to better reflect that it is a Stromer
PLL and change the apss_ipq_pll_probe() function accordingly.

Rework nss_port5/6 to use the new multiple configuration implementation
and correctly fix the clocks for these port under some corner case.
This is particularly relevant for device that have 2.5G or 10G port
connected to port5 or port 6 on ipq8074. As the parent are shared
across multiple port it may be required to select the correct
configuration to accomplish the desired clock. Without this patch such
port doesn't work in some specific ethernet speed as the clock will be
set to the wrong frequency as we just select the first configuration for
the related frequency instead of selecting the best one.

Some RCG frequency can be reached by multiple configuration.
Add clk_rcg2_fm_ops ops to support these special RCG configurations.
These alternative ops will select the frequency using a CEIL policy.
When the correct frequency is found, the correct config is selected by
calculating the final rate (by checking the defined parent and values
in the config that is being checked) and deciding based on the one that
is less different than the requested one.
These check are skipped if there is just one config for the requested
freq.
qcom_find_freq_multi is added to search the freq with the new struct
freq_multi_tbl.
__clk_rcg2_select_conf is used to select the correct conf by simulating
the final clock.
If a conf can't be found due to parent not reachable, a WARN is printed
and -EINVAL is returned.

Some RCG frequency can be reached by multiple configuration.
We currently declare multiple configuration for the same frequency but
that is not supported and always the first configuration will be taken.
These multiple configuration are needed as based on the current parent
configuration, it may be needed to use a different configuration to
reach the same frequency.
To handle this introduce 3 new macro, C, FM and FMS:
- C is used to declare a freq_conf where src, pre_div, m and n are
provided.
- FM is used to declare a freq_multi_tbl with the frequency and an
array of confs to insert all the config for the provided frequency.
- FMS is used to declare a freq_multi_tbl with the frequency and an
array of a single conf with the provided src, pre_div, m and n.
Struct clk_rcg2 is changed to add a union type to reference a simple
freq_tbl or a complex freq_multi_tbl.

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.

Since commit deebc79b28d6 ("clk: qcom: gpucc-sc8280xp: Add external
supply for GX gdsc") the GDSC supply must be treated as optional to
avoid warnings like:
gpu_cc-sc8280xp 3d90000.clock-controller: supply vdd-gfx not found, using dummy regulator
on SC8280XP.
Fortunately, the driver is already prepared to handle this by checking
that the regulator pointer is non-NULL before use.
This also avoids triggering a potential deadlock on SC8280XP even if the
underlying issue still remains for the derivative platforms like SA8295P
that actually use the supply.

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.

The following table shows the values of the 'halt_reg' and the
'enable_reg' fields from the pcie clocks defined in the current
driver:

gcc_pcie0_ahb_clk 0x75010 0x75010
gcc_pcie0_aux_clk 0x75014 0x75014

gcc_pcie0_axi_s_bridge_clk 0x75048 0x75048

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.

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.

Some Venus resets may require more time when toggling. Describe that.
The value was obtained on a best-guess basis: msm-5.4 being the base
kernel for this SoC and 4450 being somewhat close to 8350 which is known
to require a higher delay [1].
