On Spreadtrum platform, we need power off system through external SC27xx
series PMICs including the SC2720, SC2721, SC2723, SC2730 and SC2731 chips.
Thus this patch adds SC27xx series PMICs power-off support.

This patch adds common code used to power down all cores and clusters.
The code was previously based on the MCPM framework. It has now been
adapted to hook into struct smp_operations directly, but the code
structure still shows signs of prior work.
The primary core (cpu0) requires setting flags to
The A80 is a big.LITTLE SoC with 1 cluster of 4 Cortex-A7s and
1 cluster of 4 Cortex-A15s.
This patch adds support to bring up the second cluster and thus all
cores using custom platform SMP code. Core/cluster power down has not
been implemented, thus CPU hotplugging is not supported.
This is lim
The A80 includes an ARM CCI-400 interconnect to support multi-cluster
CPU caches.
Also add the maximum clock frequency for the CPUs, as listed in the
A80 Optimus Board FEX file.

CPUCFG is a collection of registers that are mapped to the SoC's signals

On the Allwinner A80 SoC the BROM supports hotplugging the primary core

The BROM has a branch that checks if the primary core is hotplugging.
If the magic flag is set, execution jumps to the address set in the

address.)

Drivers should not 'select' a subsystem. Instead they should depend
on it. If the subsystem is disabled, the user probably did that for
a purpose and one driver shouldn't be changing that.

Hi Andrew,
Today's linux-next merge of the akpm-current tree got a conflict in:

So that beautifiers wanting to resolve kernel function addresses to
names can do its work, and when we use "perf report" for output of
"perf kmem record", we will get kernel symbol output.

Don't see any preempt_disable() in do_debug() and do_page_fault(),
there is no need to call preempt_enable_no_resched() here.

The RX and TX macros were defined implicitly and there was
a potential risk if someone changes their values.
Since they were defined to index the array ssi->regvals[2],
this patch moves these two macros to fsl_ssi.c, closer to
its owner ssi->regvals. And it also puts some comments here
to limit th
This patch replaces the register read with ssi->i2s_net for
simplification. It also removes masking SSIEN from scr value
since it's handled later by regmap_update_bits() to set this
scr value back.

Checking TE and RE bits in SCR register doesn't work for AC97 mode
which enables SSIEN, TE and RE in the fsl_ssi_setup_ac97() that's

So when running into the trigger(), it will always get the result
of both TE and RE being enabled already, even if actually there is

The define of fsl_ssi_disable_val is not so clear as it mixes two
steps of calculations together. And those parameter names are also
a bit long to read.
Since it just tries to exclude the shared bits from the regvals of

The trigger() calls fsl_ssi_tx_config() and fsl_ssi_rx_config(),
and both of them jump to fsl_ssi_config(). And fsl_ssi_config()
later calls another fsl_ssi_rxtx_config().
However, the whole routine, especially fsl_ssi_config() function,
is too complicated because of the folowing reasons:

For each kprobe hook, preempt_disable() is called twice, but
preempt_enable() is called once, when CONFIG_PREEMPT=y. No
matter kprobe uses ftrace or int3. Then the preempt counter
overflows, the process might be preempted and migrate to another
cpu. It causes the kprobe int3 being t
The _fsl_ssi_set_dai_fmt() bypasses an undefined format for AC97
mode. However, it's not really necessary if AC97 has its complete
format defined.
So this patch adds a DAIFMT macro of complete format including a
clock direction and polarity.

The _fsl_ssi_set_dai_fmt() is a helper function being called from
fsl_ssi_set_dai_fmt() as an ASoC operation and fsl_ssi_hw_init()
mainly for AC97 format initialization.
This patch cleans the _fsl_ssi_set_dai_fmt() in following ways:

AC97 configures most of registers earlier to start a communication

Since now the driver has a fsl_ssi_hw_init() to handle all register
Using symmetric_rates in the cpu_dai_drv is a bit implicit,
