Clocks exposed by the PMC need to reference the PMC context for register
programming. Store a reference to the context in the data structure for
each clock to avoid the need for a global variable.

By using the generic read_poll_timeout() instead of readx_poll_timeout()
we can pass additional parameters, which allows us to pass an additional
PMC context structure and avoid relying on a global variable for this.

Currently, when resuming from system suspend on Tegra platforms,
the following warning is observed:
WARNING: CPU: 0 PID: 14459 at kernel/irq/irqdesc.c:666
Call trace:
handle_irq_desc+0x20/0x58 (P)
tegra186_pmc_wake_syscore_resume+0xe4/0x15c
syscore_resume+0x3c/0xb8
suspend_devices_and_enter+0x510/0x540
pm_suspend+0x16c/0x1d8
The warning occurs because generic_handle_irq() is being called from
a non-interrupt context which is considered as unsafe.
Fix this warning by deferring generic_handle_irq() call to an IRQ work
which gets executed in hard IRQ context where generic_handle_irq()
can be called safely.
When PREEMPT_RT kernels are used, regular IRQ work (initialized with
init_irq_work) is deferred to run in per-CPU kthreads in preemptible
context rather than hard IRQ context. Hence, use the IRQ_WORK_INIT_HARD
variant so that with PREEMPT_RT kernels, the IRQ work is processed in
hardirq context instead of being deferred to a thread which is required
for calling generic_handle_irq().
On non-PREEMPT_RT kernels, both init_irq_work() and IRQ_WORK_INIT_HARD()
execute in IRQ context, so this change has no functional impact for
standard kernel configurations.

Commit 84eaf4359c ("net: ethtool: add get_rx_ring_count callback to

* microchip/lan743x
* amd/xgbe

The fix only prevented the syzbot reproducer from triggering the bug
because the packet is not enqueued anymore and the code that triggers the
bug is not exercised.
The fix even broke

====================
net: phy: realtek: simplify and reunify C22/C45 drivers
The RTL8221B PHY variants (VB-CG and VM-CG) were previously split into
separate C22 and C45 driver instances to support copper SFP modules
using the RollBall MDIO-over-I2C protocol, which only supports Clause-45
access. However, this split created significant code duplication and
complexity.
Commit 8af2136e77 ("net: phy: realtek: add helper
RTL822X_VND2_C22_REG") exposed that RealTek PHYs map all standard
Clause-22 registers into MDIO_MMD_VEND2 at offset 0xa400.
With commit 1850ec20d6 ("net: phy: realtek: use paged access for
MDIO_MMD_VEND2 in C22 mode") it is now possible to access all MMD
registers transparently, regardless of whether the PHY is accessed via
C22 or C45 MDIO.
Further improve the translation logic for this register mapping, so a
single unified driver works efficiently with both access methods,
reducing code duplication.
The series also includes cleanup to remove unnecessary paged operations
on registers that aren't actually affected by page selection.
Testing was done on RTL8211F and RTL8221B-VB-CG (the latter in both
C22 and C45 modes).

Only registers 0x10~0x17 are affected by the value in the page
selection register 0x1f. Hence there is no point in using paged
operations when accessing any other registers.
Simplify the driver by using the normal phy_read and phy_write
operations for registers which are anyway not affected by paging.
