Subject: [PATCH 2/8] ath6kl: convert ar6004 hardware flags to firmware feature
flags
The functionality defined through these flags were actually firmware features
which can change between firmware versions. To make it possible to support
different firmware versions with the same driver, convert the flags to firmware
feature flags.
For backwards compatibility support for old ar6004 firmware FW
API 3 or smaller images we forcefully set the feature bits in the driver.
Starting from FW API 5 the firmware image needs to set them.

ACPI 5.0 spec(5.5.2.4.5) defines GenericSerialBus(i2c, spi, uart) operation region.
It allows ACPI aml code able to access such kind of devices to implement
some ACPI standard method.
ACPI Spec defines some access attribute to associate with i2c protocol.
AttribQuick Read/Write Quick Protocol
AttribSendReceive Send/Receive Byte Protocol
AttribByte Read/Write Byte Protocol
AttribWord Read/Write Word Protocol
AttribBlock Read/Write Block Protocol
AttribBytes Read/Write N-Bytes Protocol
AttribProcessCall Process Call Protocol
AttribBlockProcessCall Write Block-Read Block Process Call Protocol
AttribRawBytes Raw Read/Write N-BytesProtocol
AttribRawProcessBytes Raw Process Call Protocol
On the Asus T100TA, Bios use GenericSerialBus operation region to access
i2c device to get battery info.
Sample code From Asus T100TA
Scope (_SB.I2C1)
{
Name (UMPC, ResourceTemplate ()
{
I2cSerialBus (0x0066, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.I2C1",
0x00, ResourceConsumer, ,
)
})
...
OperationRegion (DVUM, GenericSerialBus, Zero, 0x0100)
Field (DVUM, BufferAcc, NoLock, Preserve)
{
Connection (UMPC),
Offset (0x81),
AccessAs (BufferAcc, AttribBytes (0x3E)),
FGC0, 8
}
...
}
Device (BATC)
{
Name (_HID, EisaId ("PNP0C0A")) // _HID: Hardware ID
Name (_UID, One) // _UID: Unique ID
...
Method (_BST, 0, NotSerialized) // _BST: Battery Status
{
If (LEqual (AVBL, One))
{
Store (FGC0, BFFG)
If (LNotEqual (STAT, One))
{
ShiftRight (CHST, 0x04, Local0)
And (Local0, 0x03, Local0)
If (LOr (LEqual (Local0, One), LEqual (Local0, 0x02)))
{
Store (0x02, Local1)
}
...
}
The i2c operation region is defined under I2C1 scope. _BST method under
battery device BATC read battery status from the field "FCG0". The request
would be sent to i2c operation region handler.
This patch is to add i2c ACPI operation region support. Due to there are
only "Byte" and "Bytes" protocol access on the Asus T100TA, other protocols
have not been tested.
About RawBytes and RawProcessBytes protocol, they needs specific drivers to interpret
reference data from AML code according ACPI 5.0 SPEC(5.5.2.4.5.3.9 and 5.5.2.4.5.3.10).
So far, not found such case and will add when find real case.

5/5] I2C/ACPI: Clean up I2C ACPI code and Add CONFIG_I2C_ACPI config

Clean up ACPI related code in the i2c core and add CONFIG_I2C_ACPI
to enable I2C ACPI code.
Current there is a race between removing I2C ACPI operation region
and ACPI AML code accessing. So make i2c core built-in if CONFIG_I2C_ACPI
is set.

All make sense to me. Welcome your more comments, Joe!

[PATCH] X86 platform: New Intel Atom SOC power management controller driver
The Power Management Controller (PMC) controls many of the power
management features present in the SoC. This driver provides
interface to configure the Power Management Controller (PMC).
This driver exposes PMC device state and sleep state residency
via debugfs:
/sys/kernel/debugfs/pmc_atom/dev_state
/sys/kernel/debugfs/pmc_atom/sleep_state
This driver also provides a native power off function via PMC PCI
IO port.
