Fix the issue found while running kernel with the option
CONFIG_DEBUG_TEST_DRIVER_REMOVE.
Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
few underlying 'i2c-mux-reg' devices:
priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
NULL, 0);
...
for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
priv->pdev_mux[i] = platform_device_register_resndata(
&mlxplat_dev->dev,
"i2c-mux-reg", i, NULL,
0, &mlxplat_mux_data[i],
sizeof(mlxplat_mux_data[i]));
But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
not mlxplat_dev->dev.
Patch fixes parent device parameter in a call to
platform_device_register_resndata() for "i2c-mux-reg".
It solves the race during initialization flow while 'i2c_mlxcpld.1' is
removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
'i2c_mlxcpld.1' flow: probe -> remove -> probe.
'i2c-mux-reg.0' flow: probe -> ...

When a switch event, such as tablet mode/laptop mode or docked/undocked,
wakes a device make sure that the value of the swich is reported.
Without when a device is put in tablet mode from laptop mode when it is
suspended or vice versa the device will wake up but mode will be
incorrect.
Tested by suspending a device in laptop mode and putting it in tablet
mode, the device resumes and is in tablet mode. When suspending the
device in tablet mode and putting it in laptop mode the device resumes
and is in laptop mode.

asus_nb_wmi
Commit 78f3ac76d9e5 ("platform/x86: asus-wmi: Tell the EC the OS will
handle the display off hotkey") causes the backlight to be permanently off
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).
The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
by that commit is made conditional in this commit and only enabled in
the quirk_entry structs in the asus-nb-wmi driver fixing the broken

When a new control group is created __init_one_rdt_domain() walks all
the other closids to calculate the sets of used and unused bits.
If it discovers a pseudo_locksetup group, it breaks out of the loop. This
means any later closid doesn't get its used bits added to used_b. These
bits will then get set in unused_b, and added to the new control group's
configuration, even if they were marked as exclusive for a later closid.
When encountering a pseudo_locksetup group, we should continue. This is
because "a resource group enters 'pseudo-locked' mode after the schemata is
written while the resource group is in 'pseudo-locksetup' mode." When we
find a pseudo_locksetup group, its configuration is expected to be
overwritten, we can skip it.

Apparently, some Qualcomm arm64 platforms which appear to expose their
SMMU global register space are still, in fact, using a hypervisor to
mediate it by trapping and emulating register accesses. Sadly, some
deployed versions of said trapping code have bugs wherein they go
horribly wrong for stores using r31 (i.e. XZR/WZR) as the source
register.
While this can be mitigated for GCC today by tweaking the constraints
for the implementation of writel_relaxed(), to avoid any potential
arms race with future compilers more aggressively optimising register
allocation, the simple way is to just remove all the problematic
constant zeros. For the write-only TLB operations, the actual value is
irrelevant anyway and any old nearby variable will provide a suitable
GPR to encode. The one point at which we really do need a zero to clear
a context bank happens before any of the TLB maintenance where crashes
have been reported, so is apparently not a problem... :/

The i2c2 bus has a external plug which enables the easy connection of external
"bricks" with sensors of various kinds, while i2c4 on the Extended/Full boards
has a pair of on board motion sensors, accelerometer and magnetometer on one chip
and gyroscope on another so it makes sense to enable these i2c buses for use.

Our SDVO audio support is pretty bogus. We can't push audio over the
SDVO bus, so trying to enable audio in the SDVO control register doesn't
do anything. In fact it looks like the SDVO encoder will always mix in
the audio coming over HDA, and there's no (at least documented) way to
disable that from our side. So HDMI audio does work currently on gen4
but only by luck really. On gen3 it got broken by the referenced commit.
And what has always been missing on every platform is the ELD.
To pass the ELD to the audio driver we need to write it to magic buffer
in the SDVO encoder hardware which then gets pulled out via HDA in the
other end. Ie. pretty much the same thing we had for native HDMI before
we started to just pass the ELD between the drivers. This sort of
explains why we even have that silly hardware buffer with native HDMI.
$ cat /proc/asound/card0/eld#1.0
-monitor_present 0
-eld_valid 0
+monitor_present 1
+eld_valid 1
+monitor_name LG TV
+connection_type HDMI
+...
This also fixes our state readout since we can now query the SDVO
encoder about the state of the "ELD valid" and "presence detect"
bits. As mentioned those don't actually control whether audio
gets sent over the HDMI cable, but it's the best we can do. And with
the state checker appeased we can re-enable HDMI audio for gen3.

While loading the DMC firmware we were double checking the headers made
sense, but in no place we checked that we were actually reading memory

Prior to this commit we fail to init the DSI panel on the GPD MicroPC:
https://www.indiegogo.com/projects/gpd-micropc-6-inch-handheld-industry-laptop#/
The problem is intel_dsi_vbt_init() failing with the following error:
*ERROR* Burst mode freq is less than computed
The pclk in the VBT panel modeline is 70000, together with 24 bpp and
4 lines this results in a bitrate value of 70000 * 24 / 4 = 420000.
But the target_burst_mode_freq in the VBT is 418000.
This commit works around this problem by adding an intel_fuzzy_clock_check
when target_burst_mode_freq < bitrate and setting target_burst_mode_freq to
bitrate when that checks succeeds, fixing the panel not working.

The current entry-latency-us is too short.
The proper way to convert between the device tree properties
from the vendor tree to the upstream PSCI device tree properties is:
entry-latency-us = qcom,time-overhead - qcom,latency-us
which gives
entry-latency-us = 210 - 80 = 130

This patch adds basic support for :
- Amlogic G12B, which is very similar to G12A
- The HardKernel Odroid-N2 based on the S922X SoC
The Amlogic G12B SoC is very similar with the G12A SoC, sharing
most of the features and architecture, but with these differences :
- The first CPU cluster only has 2xCortex-A53 instead of 4
- G12B has a second cluster of 4xCortex-A73
- Both cluster can achieve 2GHz instead of 1,8GHz for G12A
- CPU Clock architecture is difference, thus needing a different
compatible to handle this slight difference
- Supports a MIPI CSI input
- Embeds a Mali-G52 instead of a Mali-G31, but integration is the same
Actual support is done in the same way as for the GXM support, including
the G12A dtsi and redefining the CPU clusters.
Unlike GXM, the first cluster is different, thus needing to remove
the last 2 cpu nodes of the first cluster.
