Add a DSA driver for the seven-port switch integrated in MT7620. Keep
the existing swconfig path for device trees without a DSA ports node.
Use RXD4 source-port and TXD4 forced-port metadata with the Ralink
DSA tagger. The programming guide places TXD4 FP_BMAP at bits 27:20;
use that layout instead of the stale unused bits 26:19 definition.
Implement bridge isolation and STP, VLAN filtering, FDB and
MDB offload, ageing, flood controls, phylink, MTU limits, and
software-extended hardware MIB counters. Poll the 1000BASE-T CPU
port counters every 20 ms and the remaining ports every 200 ms to
leave scheduling margin before their 16-bit packet counters wrap at
minimum-sized line-rate traffic. DSA invokes port_stp_state_set()
before updating its cached state, so pass the pending callback state
as an override when recalculating port matrices instead of leaving
hardware one transition behind.
Correct the shared switch MIB enable register and enable all seven
port counters. The old address was inside port 0 counter space,
so this also fixes legacy swconfig initialization.
Register DSA through a bound child of the frame-engine device. This
gives the managed conduit device link the correct lifetime across
driver unbind and reprobe while the switch registers remain owned by
the existing GSW platform device.
Package the driver and tagger as kmod-dsa-mt7620 for per-device
opt-in. This keeps DSA and switchdev out of swconfig-only MT7620
images and prevents installing the DSA package together with swconfig.
Also make MDIO and frame-engine teardown safe for deferred probes and
runtime reprobes. Replace the legacy MDIO busy loop and -1 return
with readl_poll_timeout_atomic() and its real error, and reset a
still-busy frame engine before freeing DMA rings. Resolve FE and ESW
resets by name so recovery can reset FE alone, and warn if a switch
node provides neither named reset.
The netdev is devm-managed, so leave NAPI deletion to free_netdev
after unregister instead of deleting NAPI from fe_remove while the
netdev is still registered.
Tested on an MT7620N rev 2 eco 6 with 100BASE-T traffic, VLAN-aware
hardware bridging, 2026-byte MTU, FDB/MDB offload, pending STP state,
and driver unbind/rebind. The modular driver, tagger, package contents,
DSA image composition, and swconfig-only kernel configuration were
also verified.
An independent TP-Link Archer C5 v4 test exercised an external RTL8367S
DSA switch using the RTL8_4t tagger as a regression check on the
shared dsa_tag_protocol enum. It found no collision or external-switch
regression; it does not validate the MT7620 integrated-switch path.

This driver is required for the touch-inputs as well as some LEDs on the
Genexis Pulse EX400.
The driver was also sent upstream. As the EX400 is currently the only
consumer, the driver is added target-specific for ramips.
Once the driver has been accepted upstream and is provided in a kernel
release used by OpenWrt, the package should be moved to the global input
drivers.

Currently kmod-i2c-* will not get into images unless kmod-i2c-core is added to
DEVICE_PACKAGES as well. By changing the dependencies from "depends on" to
"select", we do not have the issue anymore.
Furthermore, we can remove most occurrences of the package from DEVICE_PACKAGES
and similar variables, as it is now pulled by dependent modules such as:
- kmod-hwmon-lm75
- kmod-i2c-gpio
- kmod-i2c-gpio-custom
- kmod-i2c-mux
- kmod-i2c-ralink

This reduces the needed modifications to the mainline Linux kernel and
also makes the regmap package work with an out of tree kernel which
does not have these modifications.
The regmap-core is only added when it is really build as a module.
The regmap-core is normally bool so it cannot be built as a module in an
unmodified kernel. When it is selected by on other kernel module it will
always be selected as build in and it also does not show up in
$(LINUX_DIR)/modules.builtin as it is not supposed to be a kernel module.
When it is not in $(LINUX_DIR)/modules.builtin the build system expects
it to be built as a .ko file.
Just check if the module is really there and only add it in that case.
This splits the regmap package into multiple packages, one for each bus type.
This way only the bus maps which are really needed have to be added.
This also splits the I2C, SPI and MMIO regmap into separate packages to not
require all these subsystems to build them, on an unmodified upstream kernel
this also causes problems in some situations.

With kernel 4.14 the OpenWrt specific module name collides with the
upstream added module for Mediatek ARM Socs.
During addition of preliminary support for kernel 4.14, the config
symbol used by the out of tree driver was already renamed but the ramips
kernel package wasn't updated.
Fix the build error by updating the config and kernel module name for
the kernel package.

I made a commit that added the RTC driver to the kernel config with
the intent that it would fix hctosys. Unfortunately while the RTC
driver is in there, it's connected through I2C, the driver for which
comes in module form and is thus loaded late. After this commit, it
works fine.

Commit 9ff8928bb9 renamed the snd-soc-mt7620-i2s
driver and dropped snd-soc-mt7620-wm8960 which selected CONFIG_SND_SOC_WM8960
breaking all ramips builds due to undefined kernel config symbols.
Rework the kmod-sound-mt7620 package to explicitely select the
CONFIG_SND_SOC_WM8960 symbols and change it to bundle the renamed .ko file.
Also remove the @BROKEN flag and exclude it on the rt288x subtarget instead.
