As per the display enable sequence, we need to follow the enable sequence
for slaves first with DP_TP_CTL set to Idle and configure the transcoder
port sync register to select the corersponding master, then follow the
enable sequence for master leaving DP_TP_CTL to idle.
At this point the transcoder port sync mode is configured and enabled
and the Vblanks of both ports are synchronized so then set DP_TP_CTL
for the slave and master to Normal and do post crtc enable updates.

This patch implements the transcoder port sync feature for

In case of tiled displays when the two tiles are sent across two CRTCs
over two separate DP SST connectors, we need a mechanism to synchronize
the two CRTCs and their corresponding transcoders.
So use the master-slave mode where there is one master corresponding
to last horizontal and vertical tile that needs to be genlocked with
all other slave tiles.

CRTC states. This is needed to select the master CRTC/transcoder

because the extra sanity testing should probably go to -stable, but we

Skylake logs some additional useful information in per-channel
registers in addition the the architectural status/addr/misc
logged in the machine check bank.
Pick up this information and add it to the EDAC log:
retry_rd_err_[five 32-bit register values]
Sorry, no definitions for these registers. OEMs and DIMM vendors
will be able to use them to isolate which cells in the DIMM are
causing problems.
correrrcnt[per rank corrected error counts]
Note that if additional errors are logged while these registers are
being read, you may see a jumble of values some from earlier errors,
others from later errors (since the registers report the most recent
logged error). The correrrcnt registers provide error counts per possible
rank. If these counts only change by one since the previous error logged
for this channel, then it is safe to assume that the registers logged
provide a coherent view of one error.
With this change EDAC logs look like this:

Looks like the i2c timings in high-speed mode do not work properly to
allow us to clear I2C_DISABLE bits for PRM_VOLTCTRL register and the
device reboots if I2C_DISABLE bits are cleared.
Let's configure the voltage controller i2c for low-speed mode as done in
the Motorola Mapphone Android Linux kernel. This saves us about 7mW of
power during retention compared to the high-speed values.
Let's also change the low-speed warning to pr_info about relying on the
bootloader configured low-speed values like we currently do.

The scsi async probe process is calling blk_pm_runtime_init for each lun,
and then those request queues are monitored by the block layer pm
engine (blk-pm.c). This is however, not the case for scsi-passthrough
queues, created by bsg_setup_queue().
So the ufs-bsg driver might send various commands, disregarding the pm
status of the device. This is wrong, regardless if its request queue is
pm-aware or not.

Commit 2d6f6f359f ("drm/i915: add i915_driver_modeset_remove()")
claimed removal of asymmetry in probe() and remove() calls, however, it
didn't take care of calling intel_irq_uninstall() on driver remove.
That doesn't hurt as long as we still call it from
intel_modeset_driver_remove() but in order to have full symmetry we
should call it again from i915_driver_modeset_remove().
Note that it's safe to call intel_irq_uninstall() twice thanks to
commit b318b82455 ("drm/i915: Nuke drm_driver irq vfuncs"). We may
only want to mention the case we are adding in a related FIXME comment
provided by that commit. While being at it, update the name of
function mentioned as calling it out of sequence as that name has been
changed meanwhile by commit 78dae1ac35 ("drm/i915: Propagate

On some MIPS variants (e.g. MIPS r1), vDSO clock_mode is set to
VDSO_CLOCK_NONE.
When VDSO_CLOCK_NONE is set the expected kernel behavior is to fallback
on syscalls. To do that the generic vDSO library expects UULONG_MAX as
return value of __arch_get_hw_counter().
Fix __arch_get_hw_counter() on MIPS defining a __VDSO_USE_SYSCALL case
that addressed the described scenario.

net: lpc_eth: parse phy nodes from device tree
Allow describing connected phys using device tree. This solves issues finding
the phy on the mdio bus and allows decribing the interrupt line the phy is
possibly connected to.
Changes in v3:
- rebased on net-next
- collected Reviewed-by
Changes in v2:
- move the phy decription in the mdio subnode.
====================

When connected to a micrel phy, phy_find_first doesn't work properly
because the first phy found is on address 0, the broadcast address but, the
first thing the phy driver is doing is disabling this broadcast address.
The phy is then available only on address 1 but the mdio driver doesn't
know about it.
Instead, register the mdio bus using of_mdiobus_register and try to find
the phy description in device tree before falling back to phy_find_first.
This ultimately also allows to describe the interrupt the phy is connected
to.

7211 uses a newer version of API v2 which is half way between what was
defined as API v3 and what used to be called API v2 but was used with
DPFE firmwares with major versions 1.x.x.x. Starting with **the new**
API v2, we are no longer getting loadable firmware images, so the
capability to load it is removed (like v3).
To avoid spreading more confusion, map 7268/7271/7278 to the old DPFE
API version 2, 7211 to the new API v2 and introduce the specific
commands for that, and leave newer versions to map to API v3.
