Flexcan will be disabled during suspend if no wakeup function required and

1) Keep device in suspend state (clocks disabled) if it's not openned.

On small memory system, there are lots of write IO so if we use

This patch supports new feature "zram idle/huge page writeback".
On zram-swap usecase, zram has usually many idle/huge swap pages.
It's pointless to keep in memory(ie, zram).
To solve the problem, this feature introduces idle/huge page
writeback to backing device so the goal is to save more memory
Inherently, swap device has many idle pages which are rare touched since
it was allocated. It is never problem if we use storage device as swap.
However, it's just waste for zram-swap.
This patchset supports zram idle page writeback feature.

PLLs with tuner_en bit, such as APLL1, need to disable
tuner_en before apply new frequency settings, or the new frequency
settings (pcw) will not be applied.
The tuner_en bit will be disabled during changing PLL rate
and be restored after new settings applied.

On both MT8183 & MT6765, there add "set/clr" register for
each clkmux setting, and one update register to trigger value change.
It is designed to prevent read-modify-write racing issue.
The sw design need to add a new API to handle this hw change with

On some Mediatek platforms, there are critical clocks of
clock gate type.
To register clock gate with flags CLK_IS_CRITICAL,
we need to add the flags field in mtk_gate data and register APIs.

diff -Z is used to trim the trailing whitespace when comparing the
loaded firmware file with the source firmware file. However, per the
comment in the source code, -Z should not be necessary. In testing, the
input and output files are identical.
Additionally, -Z is not a standard option and is not

Fix fw_filesystem.sh to run in an automated environment under busybox.
After this change, fw_run_tests.sh still fails at some point in fw_fallback.sh,
with error "usermode helper disabled so ignoring test". This is coming from
fw_lib.sh:verify_reqs() because $HAS_FW_LOADER_USER_HELPER is set to no
CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y is required for fw_fallback.sh.
Without it, fw_fallback.sh fails with 'usermode helper disabled so
