The cpufreq core now takes the min/max frequency constraints via QoS
requests and the CPUFREQ_ADJUST notifier is removed.
The devfreq core now supports limiting the frequency range of a device
through PM QoS make use of it instead of disabling OPPs that should
not be used.

The analogix_dp_transfer() will return -EBUSY if num_transferred is zero.
But sometimes we will send a bare address packet to start the transaction,
like drm_dp_i2c_xfer() show:
......
/* Send a bare address packet to start the transaction.
* Zero sized messages specify an address only (bare
* address) transaction.
*/
msg.buffer = NULL;
msg.size = 0;
err = drm_dp_i2c_do_msg(aux, &msg);
......
In this case, the msg->size is zero, so the num_transferred will be zero too.
We can't return -EBUSY here, let's we return num_transferred if num_transferred
equals msg->size.

Background:
- EDP software register bank is on the EDP 24m clock domain;
- CPU access EDP software register bank, need to go through EDP APB
read/write bus and EDP internal read/write bus;
- EDP APB read/write bus is on the EDP pclk clock domain;
- EDP internal read/write bus is on the EDP 24m clock domain;
- Asynchronous logic circuit is added between APB read/write bus and
Internal read/write bus;
Issue:
There is a bug on the Asynchronous logic circuit between APB read/write
bus and Internal read/write bus; This bug will be random to cause the
following wrong control/address signals sequence happen;
- For write, maybe wrong register address is wrote in;
- For read, maybe wrong register address is read out;
Workaround:
- For CPU write EDP register operation, write any register need
following three steps,
1): Read EDP_BASE+0x00 dummy register firstly, latch the dummy
register address on Reg_Address bus, to avoid next step write to
wrong register to cause function register overrun;
2): 1st time to write the EDP register you want to operate,
to latch the real write address on Reg_Address bus;
3): 2nd time to write the EDP register you want to operate,
to make sure the data is write on the real write address;
- For CPU read EDP register operation, read any register need following
two steps,
1): 1st time to read the EDP register you want to operate, to latch
the real read address on Reg_Address bus;
2): 2nd time to read the EDP register you want to operate, to make
sure the data is read out from the real read address;

The interrupt is requested before the device is powered on and
it's value in some cases cannot be reliable. It happens on some
devices that an interrupt is generated as soon as requested
before having the chance to disable the irq.

The driver reads OTP value from SoC to provide the OPP framework

Initially, the helper dev_pm_opp_get_opp_table() was supposed to be used
only for the OPP core's internal use (it tries to find an existing OPP
table and if it doesn't find one, then it allocates the OPP table).
Sometime back, the cpufreq-dt driver started using it to make sure all
the relevant resources required by the OPP core are available earlier
during initialization process to properly propagate -EPROBE_DEFER.
It worked but it also abused the API to create an OPP table, which
should be created with the help of other helpers provided by the OPP
core.
The OPP core will be updated in a later commit to limit the scope of
dev_pm_opp_get_opp_table() to only finding an existing OPP table and not
create one. This commit updates the cpufreq-dt driver before that
happens.
Now the cpufreq-dt driver creates the OPP and cpufreq tables for all the
CPUs from driver's init callback itself.
