[ Upstream commit 1fb98c855ccd7bc7f50c7a9626fbb8440454760b ]

Radxa ROCK Pi S have optional onboard SD NAND on board revision v1.1,
v1.2 and v1.3, revision v1.5 changed to use optional onboard eMMC.

The optional SD NAND typically fails to initialize:

  mmc_host mmc0: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)
  mmc0: error -110 whilst initialising SD card
  mmc_host mmc0: Bus speed (slot 0) = 300000Hz (slot req 300000Hz, actual 300000HZ div = 0)
  mmc0: error -110 whilst initialising SD card
  mmc_host mmc0: Bus speed (slot 0) = 200000Hz (slot req 200000Hz, actual 200000HZ div = 0)
  mmc0: error -110 whilst initialising SD card
  mmc_host mmc0: Bus speed (slot 0) = 100000Hz (slot req 100000Hz, actual 100000HZ div = 0)
  mmc0: error -110 whilst initialising SD card

Add pinctrl and cap-sd-highspeed to fix SD NAND initialization. Also
drop bus-width and mmc-hs200-1_8v to fix eMMC initialization on the new
v1.5 board revision, only 3v3 signal voltage is used.

<title>syscalls: fix compat_sys_io_pgetevents_time64 usage</title>

<content type='text'>
commit d3882564a77c21eb746ba5364f3fa89b88de3d61 upstream.

Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.

This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.

Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

commit 896842284c6ccba25ec9d78b7b6e62cdd507c083 upstream.

fadvise64_64() has two 64-bit arguments at the wrong alignment
for hexagon, which turns them into a 7-argument syscall that is
not supported by Linux.

The downstream musl port for hexagon actually asks for a 6-argument
version the same way we do it on arm, csky, powerpc, so make the
kernel do it the same way to avoid having to change both.

commit 3339b99ef6fe38dac43b534cba3a8a0e29fb2eff upstream.

Both of these architectures require u64 function arguments to be
passed in even/odd pairs of registers or stack slots, which in case of
sync_file_range would result in a seven-argument system call that is
not currently possible. The system call is therefore incompatible with
all existing binaries.

While it would be possible to implement support for seven arguments
like on mips, it seems better to use a six-argument version, either
with the normal argument order but misaligned as on most architectures
or with the reordered sync_file_range2() calling conventions as on
arm and powerpc.
