On an eDP connection, the eDP sink must operate only in Enhanced Framing
Mode. The Source must send only Enhanced Framing on the main link, and
must only write a '0' to DPCD 00101h: LANE_COUNT_SET Bit 7:
ENHANCED_FRAME_EN bit.
Independent of method used, DP1.2-compliant eDP Receivers shall indicate
any eDP protocol differentiation method they support through the
Receiver Capability Field of DPCD (DPCD:0000Dh).

According to commit 736706bee3 ("get rid of legacy 'get_ds()' function")
Every in-kernel use of this function defined it to KERNEL_DS (either as
an actual define, or as an inline function). It's an entirely
historical artifact, and long long long ago used to actually read the
segment selector valueof '%ds' on x86.
Which in the kernel is always KERNEL_DS.
Inspired by a patch from Jann Horn that just did this for a very small
subset of users (the ones in fs/), along with Al who suggested a script.
I then just took it to the logical extreme and removed all the remaining
gunk.
Roughly scripted with
git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/'
git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d'
plus manual fixups to remove a few unusual usage patterns, the couple of
inline function cases and to fix up a comment that had become stale.
The 'get_ds()' function remains in an x86 kvm selftest, since in user
space it actually does something relevant.

According to commit fad7c90209 ("err.h: remove deprecated PTR_RET for good").
Initially, commit fa9ee9c4b9 ("include/linux/err.h: add a function to
cast error-pointers to a return value") from Uwe Kleine-König introduced
PTR_RET in 03/2011. Then, in 07/2013, commit 6e8b8726ad ("PTR_RET is
now PTR_ERR_OR_ZERO") from Rusty Russell renamed PTR_RET to
PTR_ERR_OR_ZERO, and left PTR_RET as deprecated-marked alias.
After six years since the renaming and various repeated cleanups in the
meantime, it is time to finally remove the deprecated PTR_RET for good.

According to commit 4bdc0d676a ("remove ioremap_nocache and devm_ioremap_nocache").
ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
