devm_clk_bulk_get_optional_enable() gets, prepares and enables a set of
clocks with device-managed cleanup, but treats every clock as optional:
a missing clock is silently returned as NULL instead of failing.
Consumers that need a fixed set of mandatory clocks enabled for the
lifetime of the device currently have to open-code devm_clk_bulk_get()
followed by clk_bulk_prepare_enable(), which loses the managed disable on
unbind, or fall back to per-clock devm_clk_get_enabled() calls.
Add devm_clk_bulk_get_enable() as the non-optional counterpart. The
underlying __devm_clk_bulk_get_enable() helper already supports the
required (optional = false) path, so only export a thin wrapper for it.

Add support for resetting the PCIe lines with the PERSTOUT reset. These
special reset are controlled by the PCIC register and are specific to each
of the 3 PCIe lines.
Contrary to the dedicated reset register where 0 deassert and 1 assert the
reset line for the related bit, for PCIe PERSTOUT reset in the PCIC
register, the deassert and assert value is swapped, with 1 for deassert and
0 for assert. (HW have these bit set as 1 by default after a cold boot)
This is internally handled in the reset function.
PCI enable/disable are updated to drop PERSTOUT bits in favor dedicated

When mtk_clk_register_pllfhs function fails to register a PLL, it
unregisters all PLLs and cleans up itself in its error path before
returning, so the function callers don't need to do it.
But contrary to mtk_clk_unregister_pllfhs function, that does almost
the same sequence, it does not free the IO memory mapped on fhctl node,
leading to a leak.
Fix this leak by factorizing the cleanup sequence in a new private
function and use it both mtk_clk_register_pllfhs and
mtk_clk_unregister_pllfhs functions.
Also, change the loop index start value to avoid the -1 operation on

Commit 44f9200699 ("Input: gscps2 - use guard notation when
acquiring spinlock") moved the receive loop into gscps2_read_data()
and gscps2_report_data().
While moving the code, it preserved the writes to
buffer[ps2port->append], but omitted the following producer index
update from the original loop:
ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;
As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.
Restore the omitted index update.

Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.
Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).
Revert the incorrect address calculation introduced in commit
a98518e724.

The current list initialisation depends on the well hidden two zeros in
the PCI_VDEVICE macro. Instead use a named initialisation that is more
robust and easier to understand.

When BAR_PEER_SPAD and BAR_CONFIG share one PCI BAR, the module teardown
path ends up calling pci_iounmap() on the same iomem with some offset,
which is unnecessary and triggers a kernel warning like the following:
