According to the AMD IOMMU spec, the commit 73db2fc595f3
("iommu/amd: Increase interrupt remapping table limit to 512 entries")
also requires the interrupt table length (IntTabLen) to be set to 9
(power of 2) in the device table mapping entry (DTE).

Two files under drivers/macintosh are actually m68k-only. I think that
patches for these files should be reviewed in the appropriate forum and
merged via the appropriate tree, rather than falling to the powerpc
maintainers to deal with. Update the "M68K ON APPLE MACINTOSH" section
accordingly.

The behaviour of the IOP firmware is not well documented but we do know
that IOP message reply data can be used to issue new ADB commands.
Use the message reply to better control autopoll behaviour by sending
a Talk Register 0 command after every ADB response, not unlike the
algorithm in the via-macii driver. This poll command is addressed to
that device which last received a Talk command (explicit or otherwise).

A recent patch incorrectly altered the adb-iop state machine behaviour
and introduced a regression that can appear intermittently as a
malfunctioning ADB input device. This seems to be caused when reply
packets from different ADB commands become mixed up, especially during
the adb bus scan. Fix this by unconditionally entering the awaiting_reply
state after sending an explicit command, even when the ADB command won't
generate a reply from the ADB device.
It turns out that the IOP always generates reply messages, even when the
ADB command does not produce a reply packet (e.g. ADB Listen command).
So it's not really the ADB reply packets that are being mixed up, it's the
IOP messages that enclose them. The bug goes like this:
1. CPU sends a message to the IOP, expecting no response because this
message contains an ADB Listen command. The ADB command is now
considered complete.
2. CPU sends a second message to the IOP, this time expecting a
response because this message contains an ADB Talk command. This
ADB command needs a reply before it can be completed.
3. adb-iop driver receives an IOP message and assumes that it relates
to the Talk command. It's actually an empty one (with flags ==
ADB_IOP_EXPLICIT|ADB_IOP_TIMEOUT) for the previous command. The
Talk command is now considered complete but it gets the wrong reply
data.
4. adb-iop driver gets another IOP response message, which contains
the actual reply data for the Talk command, but this is dropped
(the driver is no longer in awaiting_reply state).

hclge_dbg_reg_info[] is defined as an array of packed structure
accidentally. However, this array contains pointers, which are
no longer aligned naturally, and cannot be relocated on PPC64.
Hence, when compile-testing this driver on PPC64 with
CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be
some warnings.
Since each field in structure hclge_qos_pri_map_cmd and
hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary
for these two structures as well, so remove the pragma packed in
hclge_debugfs.h to fix this issue, and this increases
hclge_dbg_reg_info[] by 4 bytes per entry.

The Tegra194 CPUFREQ driver sets the CPUFREQ_NEED_INITIAL_FREQ_CHECK
flag which means that the CPUFREQ framework will call the 'get' callback
on boot to determine the current frequency of the CPUs. Therefore, it is
not necessary for the Tegra194 CPUFREQ driver to internally call the
tegra194_get_speed_common() during initialisation to query the current
frequency as well. Fix this by removing the call to the
tegra194_get_speed_common() during initialisation and simplify the code.

The CPUFREQ driver framework references each individual CPUs when
getting and setting the speed. Tegra186 has 3 clusters of A57 CPUs and
1 cluster of Denver CPUs. Hence, the Tegra186 CPUFREQ driver need to
know which cluster a given CPU belongs to. The logic in the Tegra186
driver can be greatly simplified by storing the cluster ID associated
with each CPU in the tegra186_cpufreq_cpu structure. This allow us to
completely remove the Tegra cluster info structure from the driver and
simplifiy the code.

The Tegra186 CPUFREQ driver is using the policy->driver_data variable to
store and iomem pointer to a Tegra186 CPU register that is used to set
the clock speed for the CPU. This is not necessary because the register
base address is already stored in the driver data and the offset of the
register for each CPU is static. Therefore, fix this by adding a new
structure with the register offsets for each CPU and store this in the
main driver data structure along with the register base address. Please
note that a new structure has been added for storing the register
offsets rather than a simple array, because this will permit further
clean-ups and simplification of the driver.

Raydium device does not like splitting of tx transactions into multiple
messages - one for the register address and one for the actual data. This
results in incorrect behavior on the device side.
This change updates raydium_i2c_read and raydium_i2c_write to create
i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer
which decides based on the address whether the bank switch command should
be sent. The bank switch header is still added by raydium_i2c_read and
raydium_i2c_write to ensure that all these operations are performed as part
of a single I2C transfer. It guarantees that no other transactions are
initiated to any other device on the same bus after the bank switch command
is sent.

Previously we were using count-weight of the T124 for T30 in order to
get EMC clock rate that was reasonable for T30. In fact the count-weight
should be x2 times smaller on T30, but then devfreq was producing a bit
too low EMC clock rate for ISO memory clients, like display controller
for example.
Now both Tegra ACTMON and Tegra DRM display drivers support interconnect
framework and display driver tells to ICC what a minimum memory bandwidth
is needed, preventing FIFO underflows. Thus, now we can use a proper
count-weight value for Tegra30 and MC_ALL device config needs a bit more
aggressive boosting.
Add a separate ACTMON driver configuration that is specific to Tegra30.

This patch moves ACTMON driver away from generating OPP table by itself,
transitioning it to use the table which comes from device-tree. This
change breaks compatibility with older device-trees and brings support
for the interconnect framework to the driver. This is a mandatory change
which needs to be done in order to implement interconnect-based memory
DVFS, i.e. device-trees need to be updated. Now ACTMON issues a memory
bandwidth requests using dev_pm_opp_set_bw() instead of driving EMC clock
rate directly.
