* add rt_i2c structure to store driver data
* rewrite read/write check function and add i2c error status check.
so we don't need to wait until time out.
* add 10 bits address support. according to the data sheet i think
it is possible. but i haven't verify it.
* the most important is start transfer only need once. otherwise
it cause I2C_STARTERR status.
* add set i2c clock speed register by dts options "clock-frequency".
not just hard code it.
* add mt7621 i2c driver. i just copy i2c-ralink.c and change register
names. and the hardware don't support error status. so i remove it.
but the logic is the same.

* fix compiler error. device_control operation not support now.
* add old chips support 8 channels. new chips support 16 channels.
* add mt7621 hsdma driver. data sheet says it has two channels.
but after test only one channel support.
* add memory to memory DMA support. i use dmatest kernel module to
verify this function. on rt305x it will copy more data. on mt7621
only two channels can works at the same time. these two chips
maybe have hardware bugs. because on other chips don't have these bugs.
* use tasklet to handle remaining dma requests.

In commit "regulator: qcom: Rework to single platform device" the smb208
regulator used in IPQ8064 was left out.
Add it to that new framework and update Docs and DT accordingly.

this worked in 3.18 but broke at some point. the old code that loaded a
irq table was incorrewct anyhow as it mapped the irqs int he domain which
should really be done when the driver using them loads them and not the
irq driver itself.

The swconfig kernel infrastructure fails to do any permissions checks when
changing settings. As such an ordinary user account on a device with a
switch can change switch settings without any special permissions.
Routers generally have few non-admin users so this isn't a big hole, but it
is a security hole. Likely the greatest danger is for multifunction devices
which have a lot of extra daemons, compromising a low-security daemon would
allow one to modify switch settings and cause the router/switch to appear to
lock-up (or cause other sorts of troublesome nyetwork behavior).
Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any
requests originating from user contexts lacking this capability.

Now that deviations to the default /etc/config/system are registered via
board.d we can drop the target specific copy.

The system config file shipped by ath25 is now equivalent to the generic one
in base files, so drop the target specific copy.

The ath25 target has its own unique button action config support, which is not
used anywhere except for two example logger statements in UCI.
Since there is a generic /etc/rc.button facility since some time already there
is no reason at all to keep this target specific mechanism anymore, so simply
drop it.

Upstream dropped the `dapm` member of `struct snd_soc_component`, requiring
users to access it using `snd_soc_codec_get_dapm()` instead so change the
driver code to do just that.
Fixes the following build error spotted by the buildbots:
