Add the CLK_SET_RATE_PARENT flag to divider clock registration so that rate
changes can propagate to parent clocks when needed. This allows the CPG
divider clocks to request rate adjustments from their parent, ensuring
correct frequency scaling and improved flexibility in clock rate selection.

The FRQCRB register on R-Car V3U, V4H and V4M do in addition to the
already supported KICK bit contain settings for the frequency division
ratios for the clocks ZTR, ZT, ZS and ZG. It is however not possible to
use the latter when registering a Z clock with the DEF_GEN4_Z() macro.
This change adds support for that by extending the existing practice of
treating the bit field offsets at multiples of 32 to map to a different
register. With this new mapping in palace
bit offsets 0 - 31 map to FRQCRC0
bit offsets 32 - 63 map to FRQCRC1
bit offsets 64 - 95 map to FRQCRB
The change also adds an error condition to return an error if an unknown
offset is used.
The KICK bit defined in FRQCRB and already supported covers all three
registers and no addition to how it is handled are needed.

Add support for PLLDSI and its post-dividers in the RZ/V2H CPG driver and
export helper APIs for use by the DSI driver.
Introduce per-PLL-DSI state in the CPG private structure and provide a
set of helper functions that find valid PLL parameter combinations for
a requested frequency. The new helpers are rzv2h_get_pll_pars(),
rzv2h_get_pll_div_pars(), rzv2h_get_pll_divs_pars() and
rzv2h_get_pll_dtable_pars() and they are exported in the "RZV2H_CPG"
namespace for use by other consumers (notably the DSI driver). These
helpers perform iterative searches over PLL parameters (M, K, P, S)
and optional post-dividers and return the best match (or an exact
match when possible).
Move PLL/CLK related limits and parameter types into the shared
include (include/linux/clk/renesas.h) by adding struct rzv2h_pll_limits,
struct rzv2h_pll_pars and struct rzv2h_pll_div_pars plus the
RZV2H_CPG_PLL_DSI_LIMITS() helper macro to define DSI PLL limits.
This change centralises the PLLDSI algorithms so the CPG and DSI
drivers compute PLL parameters consistently and allows the DSI driver
to accurately request rates and program its PLL.

On the RZ/T2H SoC, a specific sequence is required when releasing a
module from the module stop state (i.e. when clearing the corresponding
bit in the MSTPCRm register to '0'). After writing to the MSTPCRm
register, a read-back of the same register must be performed, followed
by at least seven dummy reads of any register within the IP block that
is being released.
To avoid mapping device registers for this purpose, a short delay is
introduced after the read-back to ensure proper hardware stabilization
before the module becomes accessible.

Add support for module reset handling on the RZ/T2H SoC. Unlike earlier
CPG/MSSR variants, RZ/T2H uses a unified set of Module Reset Control
Registers (MRCR) where both reset and deassert actions are done via
read-modify-write (RMW) to the same register.
Introduce a new MRCR offset table (mrcr_for_rzt2h) for RZ/T2H and assign
it to reset_regs. For this SoC, the number of resets is based on the
number of MRCR registers rather than the number of module clocks. Also
add cpg_mrcr_reset_ops to implement reset, assert, and deassert using RMW
while holding the spinlock. This follows the RZ/T2H requirements, where
processing after releasing a module reset must be secured by performing
seven dummy reads of the same register, and where a module that is reset
and released again must ensure the target bit in the Module Reset Control
Register is set to 1.
Update the reset controller registration to select cpg_mrcr_reset_ops for
RZ/T2H, while keeping the existing cpg_mssr_reset_ops for other SoCs.

The use of IS_ERR_OR_NULL() suggests that "clk" can be a NULL pointer.
Hence smatch assumes so, and issues a "passing zero to 'PTR_ERR'"
warning.
At these checkpoints, "clk" always contains either a valid pointer, or
an error pointer (none of the functions called return NULL pointers).
Hence replace IS_ERR_OR_NULL() by IS_ERR().

On R-Car V4H, the PCIEC controller DBI read would generate an SError in
case the controller reset is released by writing SRSTCLR register first,
and immediately afterward reading some PCIEC controller DBI register.
The issue triggers in rcar_gen4_pcie_additional_common_init() on
dw_pcie_readl_dbi(dw, PCIE_PORT_LANE_SKEW), which on V4H is the first
read after reset_control_deassert(dw->core_rsts[DW_PCIE_PWR_RST].rstc).
The reset controller which contains the SRSTCLR register and the PCIEC
controller which contains the DBI register share the same root access
bus, but the bus then splits into separate segments before reaching each
IP. Even if the SRSTCLR write access was posted on the bus before the
DBI read access, it seems the DBI read access may reach the PCIEC
controller before the SRSTCLR write completed, and trigger the SError.
Mitigate the issue by adding a dummy SRSTCLR read, which assures the
SRSTCLR write completes fully and is latched into the reset controller,
before the PCIEC DBI read access can occur.

The previous fix to trace_marker required updating trace_marker_raw
as well. The difference between trace_marker_raw from trace_marker
is that the raw version is for applications to write binary structures
directly into the ring buffer instead of writing ASCII strings.
This is for applications that will read the raw data from the ring
buffer and get the data structures directly. It's a bit quicker than
using the ASCII version.
Unfortunately, it appears that our test suite has several tests that
test writes to the trace_marker file, but lacks any tests to the
trace_marker_raw file (this needs to be remedied). Two issues came
about the update to the trace_marker_raw file that syzbot found:
- Fix tracing_mark_raw_write() to use per CPU buffer
The fix to use the per CPU buffer to copy from user space was needed for
both the trace_maker and trace_maker_raw file.
The fix for reading from user space into per CPU buffers properly fixed
the trace_marker write function, but the trace_marker_raw file wasn't
fixed properly. The user space data was correctly written into the per CPU
buffer, but the code that wrote into the ring buffer still used the user
space pointer and not the per CPU buffer that had the user space data
already written.
- Stop the fortify string warning from writing into trace_marker_raw
After converting the copy_from_user_nofault() into a memcpy(), another
issue appeared. As writes to the trace_marker_raw expects binary data, the
first entry is a 4 byte identifier. The entry structure is defined as:
struct {
struct trace_entry ent;
int id;
char buf[];
};
The size of this structure is reserved on the ring buffer with:
size = sizeof(*entry) + cnt;
Then it is copied from the buffer into the ring buffer with:
memcpy(&entry->id, buf, cnt);
This use to be a copy_from_user_nofault(), but now converting it to
a memcpy() triggers the fortify-string code, and causes a warning.
The allocated space is actually more than what is copied, as the cnt
used also includes the entry->id portion. Allocating sizeof(*entry)
plus cnt is actually allocating 4 bytes more than what is needed.
Change the size function to:
size = struct_size(entry, buf, cnt - sizeof(entry->id));
And update the memcpy() to unsafe_memcpy().

The fix to use a per CPU buffer to read user space tested only the writes
to trace_marker. But it appears that the selftests are missing tests to
the trace_maker_raw file. The trace_maker_raw file is used by applications
that writes data structures and not strings into the file, and the tools
read the raw ring buffer to process the structures it writes.
The fix that reads the per CPU buffers passes the new per CPU buffer to
the trace_marker file writes, but the update to the trace_marker_raw write
read the data from user space into the per CPU buffer, but then still used
then passed the user space address to the function that records the data.
Pass in the per CPU buffer and not the user space address.
TODO: Add a test to better test trace_marker_raw.

After commit 5ab23c7923 ("modpost: Create modalias for builtin
modules"), relocatable RISC-V kernels with CONFIG_KASAN=y start failing
when attempting to strip the module device table symbols:
riscv64-linux-objcopy: not stripping symbol `__mod_device_table__kmod_irq_starfive_jh8100_intc__of__starfive_intc_irqchip_match_table' because it is named in a relocation
make[4]: *** [scripts/Makefile.vmlinux:97: vmlinux] Error 1
The relocation appears to come from .LASANLOC5 in .data.rel.local:
$ llvm-objdump --disassemble-symbols=.LASANLOC5 --disassemble-all -r drivers/irqchip/irq-starfive-jh8100-intc.o
drivers/irqchip/irq-starfive-jh8100-intc.o: file format elf64-littleriscv
Disassembly of section .data.rel.local:
0000000000000180 <.LASANLOC5>:
...
1d0: 0000 unimp
00000000000001d0: R_RISCV_64 __mod_device_table__kmod_irq_starfive_jh8100_intc__of__starfive_intc_irqchip_match_table
...
This section appears to come from GCC for including additional
information about global variables that may be protected by KASAN.
There appears to be no way to opt out of the generation of these symbols
through either a flag or attribute. Attempting to remove '.LASANLOC*'
with '--strip-symbol' results in the same error as above because these
symbols may refer to (thus have relocation between) each other.
Avoid this build breakage by switching to '--strip-unneeded-symbol' for
removing __mod_device_table__ symbols, as it will only remove the symbol
when there is no relocation pointing to it. While this may result in a
little more bloat in the symbol table in certain configurations, it is
not as bad as outright build failures.
