According to the downstream driver the DDRMON_CTRL_LPDDR23 bit must be
set for both LPDDR2 and LPDDR3. Add the missing LPDDR2 case and while
at it turn the if/else if/else into switch/case which makes it easier

Use the HIWORD_UPDATE() define known from other rockchip drivers to
make the defines look less odd to the readers who've seen other
rockchip drivers.
The HIWORD registers have their functional bits in the lower 16 bits
whereas the upper 16 bits contain a mask. Only the functional bits that
have the corresponding mask bit set are modified during a write. Although
the register writes look different, the end result should be the same,
at least there's no functional change intended with this patch.

The DDRTYPE defines are named to be RK3399 specific, but they can be
used for other Rockchip SoCs as well, so replace the RK3399_PMUGRF_
prefix with ROCKCHIP_. They are defined in a SoC specific header
file, so when generalizing the prefix also move the new defines to
a SoC agnostic header file. While at it use GENMASK to define the
DDRTYPE bitfield and give it a name including the full register name.

'type' is write-only. Delete all three.
The function iavf_set_mac_type that sets 'type' also checks if the PCI
vendor ID is Intel. This is unnecessary. Delete the whole function.
If in the future there's a need for the MAC type (or other PCI

Johannes Zink says:
====================
net: stmmac: use correct PPS input indexing
The stmmac can have 0 to 4 auxiliary snapshot in channels, which can be
used for capturing external triggers with respect to the eqos PTP timer.
Previously when enabling the auxiliary snapshot, an invalid request was
written to the hardware register, except for the Intel variant of this
driver, where the only snapshot available was hardcoded.
Patch 1 of this series cleans up the debug netdev_dbg message indicating
the auxiliary snapshot being {en,dis}abled. No functional changes here
Patch 2 of this series writes the correct PPS input indexing to the
hardware registers instead of a previously used fixed value
Patch 3 of this series removes a field member from plat_stmmacnet_data
that is no longer needed
Patch 4 of this series prepares Patch 5 by protecting the snapshot
enabled flag by the aux_ts_lock mutex
Patch 5 of this series adds a temporary workaround, since at the moment
the driver can handle only one single auxiliary snapshot at a time.
Previously the driver silently dropped the previous configuration and
enabled the new one. Now, if a snapshot is already enabled and userspace
tries to enable another without previously disabling the snapshot currently
enabled: issue a netdev_err and return an errorcode indicating the device is
busy.
This series is a "never worked, doesn't hurt anyone" touchup to the PPS
capture for non-intel variants of the dwmac driver.

Even though the hardware theoretically supports up to 4 simultaneous
auxiliary snapshot capture channels, the stmmac driver does support only
a single channel to be active at a time.
Previously in case of a PTP_CLK_REQ_EXTTS request, previously active
auxiliary snapshot capture channels were silently dropped and the new
channel was activated.
Instead of silently changing the state for all consumers, log an error
and return -EBUSY if a channel is already in use in order to signal to
userspace to disable the currently active channel before enabling another one.

This is a preparation patch. The next patch will check if an external TS
is active and return with an error. So we have to move the change of the
plat->flags that tracks if external timestamping is enabled after that
check.
Prepare for this change and move the plat->flags change into the mutex
and the if (on).

Do not store bitmask for enabling AUX_SNAPSHOT0. The previous commit

The stmmac supports up to 4 auxiliary snapshots that can be enabled by
setting the appropriate bits in the PTP_ACR bitfield.
Previously as of commit f4da56529d ("net: stmmac: Add support for
external trigger timestamping") instead of setting the bits, a fixed
value was written to this bitfield instead of passing the appropriate
bitmask.
Now the correct bit is set according to the ptp_clock_request.extts_index
passed as a parameter to stmmac_enable().

macros for framebuffers in I/O address space. Set the read/write,
draw and mmap callbacks to the correct implementation and avoid
implicit defaults. Also select the necessary I/O helpers in Kconfig.
Fbdev drivers sometimes rely on the callbacks being NULL for a
default implementation to be invoked; hence requiring the I/O
helpers to be built in any case. Setting all callbacks in all
drivers explicitly will allow to make the I/O helpers optional.
This benefits systems that do not use these functions.
No functional changes.
