[ Upstream commit 2607133196c35f31892ee199ce7ffa717bea4ad1 ]

These clkdevs were unnecessary, because systems using this driver always
look up clocks using the devicetree. And as Russell King points out[1],
since the provided device name was truncated, lookups via clkdev would
never match.

Recently, commit 8d532528ff6a ("clkdev: report over-sized strings when
creating clkdev entries") caused clkdev registration to fail due to the
truncation, and this now prevents the driver from probing. Fix the
driver by removing the clkdev registration.

<title>clk: qcom: apss-ipq-pll: use stromer ops for IPQ5018 to fix boot failure</title>

commit 5fce38e2a1a97900989d9fedebcf5a4dacdaee30 upstream.

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.

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

commit 6dc445c1905096b2ed4db1a84570375b4e00cc0f upstream.

Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with
__counted_by") annotated the hws member of 'struct clk_hw_onecell_data'
with __counted_by, which informs the bounds sanitizer about the number
of elements in hws, so that it can warn when hws is accessed out of
bounds. As noted in that change, the __counted_by member must be
initialized with the number of elements before the first array access
happens, otherwise there will be a warning from each access prior to the
initialization because the number of elements is zero. This occurs in
raspberrypi_discover_clocks() due to -&gt;num being assigned after -&gt;hws
has been accessed:

  UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-raspberrypi.c:374:4
  index 3 is out of range for type 'struct clk_hw *[] __counted_by(num)' (aka 'struct clk_hw *[]')

Move the -&gt;num initialization to before the first access of -&gt;hws, which
clears up the warning.

[ Upstream commit c55f7ee2ec239b6afd8639c7ac06493876deb0ea ]

According to ipq5018.dtsi, the maximum supported rate by the
CPU is 1.008 GHz on the IPQ5018 platform, however the current
configuration of the PLL results in 1.2 GHz rate.

Change the 'L' value in the PLL configuration to limit the
rate to 1.008 GHz. The downstream kernel also uses the same
value [1]. Also add a comment to indicate the desired
frequency.

configuration of the PLL results in 1.2 GHz rate.

Change the 'L' value in the PLL configuration to limit the
rate to 1.008 GHz. The downstream kernel also uses the same
value [1]. Also add a comment to indicate the desired
frequency.

[ Upstream commit 07fb0a76bb757990b99fc2ab78ad7d1709cc441d ]

CONFIG_SM_GCC_8650 depends on ARM64 but it is selected by
CONFIG_SM_GPUCC_8650, which can be selected on ARM, resulting in a
Kconfig warning.

WARNING: unmet direct dependencies detected for SM_GCC_8650

[ Upstream commit e20ae5ae9f0c843aded4f06f3d1cab7384789e92 ]

Right now, msm8998 video decoder (venus) is non-functional:

Bryan O'Donoghue suggested the proper fix:
- Set required register offsets in venus GDSC structs.
- Set HW_CTRL flag.

[ Upstream commit 615a292ee4d51303246278f3fa33cc38700fe00e ]

On SM8650 DisplayPort link clocks use frequency tables inherited from
the vendor kernel, it is not applicable in the upstream kernel. Drop
frequency tables and use clk_byte2_ops for those clocks.

This fixes frequency selection in the OPP core (which otherwise attempts
to use invalid 810 KHz as DP link rate), also fixing the following
message:
msm-dp-display af54000.displayport-controller: _opp_config_clk_single: failed to set clock rate: -22
