Fast mode plus is available on most of the IP variants that RIIC driver
is working with. The exception is (according to HW manuals of the SoCs
where this IP is available) the Renesas RZ/A1H. For this, patch
introduces the struct riic_of_data::fast_mode_plus.
Fast mode plus was tested on RZ/G3S, RZ/G2{L,UL,LC}, RZ/Five by
instantiating the RIIC frequency to 1MHz and issuing i2c reads on the
fast mode plus capable devices (and the i2c clock frequency was checked on
RZ/G3S).

Define individual arrays to describe the register offsets. In this way
we can describe different IP variants that share the same register offsets
but have differences in other characteristics. Commit prepares for the
addition of fast mode plus.

Add suspend/resume support for the RIIC driver. This is necessary for the
Renesas RZ/G3S SoC which support suspend to deep sleep state where power
to most of the SoC components is turned off. As a result the I2C controller
needs to be reconfigured after suspend/resume. For this, the reset line
was stored in the driver private data structure as well as i2c timings.
The reset line and I2C timings are necessary to re-initialize the
controller after resume.

Enable runtime PM autosuspend support for the RIIC driver. With this, in
case there are consecutive xfer requests the device wouldn't be runtime
enabled/disabled after each consecutive xfer but after the
the delay configured by user. With this, we can avoid touching hardware
registers involved in runtime PM suspend/resume saving in this way some
cycles. The default chosen autosuspend delay is zero to keep the
previous driver behavior.

pm_runtime_get_sync() may return with error. In case it returns with error
dev->power.usage_count needs to be decremented. pm_runtime_resume_and_get()
takes care of this. Thus use it.

There is no need to runtime resume the device as long as the IP registers
are not accessed. Calling pm_runtime_get_sync() at the register access
time leads to a simpler error path.

Replace SET_RUNTIME_PM_OPS() with its modern RUNTIME_PM_OPS()
alternative.
The combined usage of pm_ptr() and RUNTIME_PM_OPS() allows the
compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.
This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.

Avoid a double initialization of this variable by transferring the

When disabling CONFIG_X86_AMD_PLATFORM_DEVICE option, the driver
'drivers/acpi/acpi_apd.c' won't be compiled. This leads to a situation
where BMC (Baseboard Management Controller) cannot retrieve the memory
temperature via the i2c interface after i2c DW driver is loaded. Note
that BMC can retrieve the memory temperature before booting into OS.
[Debugging Detail]
1. dev->pclk and dev->clk are NULL when calling devm_clk_get_optional()
in dw_i2c_plat_probe().
2. The callings of i2c_dw_scl_hcnt() in i2c_dw_set_timings_master()
return 65528 (-8 in integer format) or 65533 (-3 in integer format).
The following log shows SS's HCNT/LCNT:
i2c_designware AMDI0010:01: Standard Mode HCNT:LCNT = 65533:65535
3. The callings of i2c_dw_scl_lcnt() in i2c_dw_set_timings_master()
return 65535 (-1 in integer format). The following log shows SS's
HCNT/LCNT:
i2c_designware AMDI0010:01: Fast Mode HCNT:LCNT = 65533:65535
4. i2c_dw_init_master() configures the register IC_SS_SCL_HCNT with
the value 65533. However, the DW i2c databook mentioned the value
cannot be higher than 65525. Quote from the DW i2c databook:
NOTE: This register must not be programmed to a value higher than
65525, because DW_apb_i2c uses a 16-bit counter to flag an
I2C bus idle condition when this counter reaches a value of
IC_SS_SCL_HCNT + 10.
5. Since ss_hcnt, ss_lcnt, fs_hcnt, and fs_lcnt are the invalid
values, we should not write the corresponding registers.
Fix the issue by reading dev->{ss,fs,hs}_hcnt and dev->{ss,fs,hs}_lcnt
from HW registers if ic_clk is not set.

Pull clk fixes from Stephen Boyd:
"A pile of Qualcomm clk driver fixes with two main themes: the alpha
PLL driver and shared RCGs, and one fix for the Starfive JH7110 SoC.
- The Alpha PLL clk_ops had multiple problems around setting rates.
There are a handful of patches here that fix masks and skip
enabling the clk from set_rate() when the PLL is disabled. The PLLs
are crucial to operation of the system as almost all frequencies in
the system are derived from them.
- Parking shared RCGs at a slow always on clk at registration time
breaks stuff.
USB host mode can't handle such a slow frequency and the serial
console gets all garbled when the UART clk is handed over to the
kernel. There's a few patches that don't use the shared clk_ops for
the UART clks and another one to skip parking the USB clk at
registration time.
- The Starfive PLL driver used for the CPU was busted causing cpufreq
to fail because the clk didn't change to a safe parent during
set_rate().
The fix is to register a notifier and switch to a safe parent so
the PLL can change rate in a glitch free manner"

The commit 783bf5d09f86 ("spi: spi-fsl-lpspi: limit PRESCALE bit in
TCR register") doesn't implement the prescaler maximum as intended.
The maximum allowed value for i.MX93 should be 1 and for i.MX7ULP
it should be 7. So this needs also a adjustment of the comparison
in the scldiv calculation.

The pwm devices for a pwm_chip are numbered starting at 0, the first hw
channel however has the number 1. While introducing a parametrised macro
to simplify register bit usage and making that offset explicit, one of
the usages was converted wrongly. This is fixed here.

Deferred I/O requires struct page for framebuffer memory, which is
not guaranteed for all DMA ranges. We thus only install deferred I/O
if we have a framebuffer that requires it.
A reported bug affected the ipu-v3 and pl111 drivers, which have video
memory in either Normal or HighMem zones
[ 0.000000] Zone ranges:
[ 0.000000] Normal [mem 0x0000000010000000-0x000000003fffffff]
[ 0.000000] HighMem [mem 0x0000000040000000-0x000000004fffffff]
where deferred I/O only works correctly with HighMem. See the Closes
tags for bug reports.

In the off-chance that waiting for the firmware to signal its booted status
timed out in the fast reset path, one must flush the cache lines for the
entire FW VM address space before reloading the regions, otherwise stale
values eventually lead to a scheduler job timeout.

We were allowing any users to create a high priority group without any
permission checks. As a result, this was allowing possible denial of
service.
We now only allow the DRM master or users with the CAP_SYS_NICE
capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM.
As the sole user of that uAPI lives in Mesa and hardcode a value of
MEDIUM [1], this should be safe to do.
Additionally, as those checks are performed at the ioctl level,
panthor_group_create now only check for priority level validity.

Tony Nguyen says:
====================
ice: fix synchronization between .ndo_bpf() and reset
Larysa Zaremba says:
PF reset can be triggered asynchronously, by tx_timeout or by a user. With some
unfortunate timings both ice_vsi_rebuild() and .ndo_bpf will try to access and
modify XDP rings at the same time, causing system crash.
The first patch factors out rtnl-locked code from VSI rebuild code to avoid
deadlock. The following changes lock rebuild and .ndo_bpf() critical sections
with an internal mutex as well and provide complementary fixes.
* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
ice: do not bring the VSI up, if it was down before the XDP setup
ice: remove ICE_CFG_BUSY locking from AF_XDP code
ice: check ICE_VSI_DOWN under rtnl_lock when preparing for reset
ice: check for XDP rings instead of bpf program when unconfiguring
ice: protect XDP configuration with a mutex
ice: move netif_queue_set_napi to rtnl-protected sections
