Subject: [PATCH] drm/bridge: it6505: Fix inverted reset polarity
The IT6505 bridge chip has a active low reset line. Since it is a
"reset" and not an "enable" line, the GPIO should be asserted to
put it in reset and deasserted to bring it out of reset during
the power on sequence.
The polarity was inverted when the driver was first introduced, likely
because the device family that was targeted had an inverting level
shifter on the reset line.
The MT8186 Corsola devices already have the IT6505 in their device tree,
but the whole display pipeline is actually disabled and won't be enabled
until some remaining issues are sorted out. The other known user is
the MT8183 Kukui / Jacuzzi family; their device trees currently do not
have the IT6505 included.
Fix the polarity in the driver while there are no actual users.

From: Luca Stefani <luca.stefani.ge1(a)gmail.com>
There are reports that system cannot suspend due to running trim because
the task responsible for trimming the device isn't able to finish in
time, especially since we have a free extent discarding phase, which can
trim a lot of unallocated space. There are no limits on the trim size
(unlike the block group part).
Since trime isn't a critical call it can be interrupted at any time,
in such cases we stop the trim, report the amount of discarded bytes and
return an error.
