Several single string flash controllers of TI have similar register map

and lm3648.
Why not to name it as lm3648 to be in align with other drivers?
I tried to match it with the above line. I will fix it.
Or even better solution (I suppose) to create a "library" and on top of
that one driver per each device?
Sakari, what do you think?
Sakrai, I'd like to keep it but please let me know your opinion.

[RFC v6 1/2] backlight: add new tps611xx backlight driver
This driver is a general version for tps611xx backlgiht chips of TI.
It supports tps61158, tps61161, tps61163 and tps61165 backlight driver
based on EasyScale protocol(1-Wire Control Interface).
EasyScale
EasyScale is a simple but flexible one pin interface to configure the current.
The interface is based on a master-slave structure, where the master is
typically a microcontroller or application processor and the IC is the slave.
The advantage of EasyScale compared with other one pin interfaces is that
its bit detection is in a large extent independent from the bit transmission
rate. It can automatically detect bit rates between 1.7kBit/sec and up
to 160kBit/sec.
EasyScale on TPS61163
A command consists of 24 bits, including an 8-bit device address byte and
a 16-bit data byte. All of the 24 bits should be transmitted together each
time, and the LSB bit should be transmitted first. The device address byte
A7(MSB)~A0(LSB) is fixed to 0x8F.
The data byte includes 9 bits D8(MSB)~D0(LSB) for brightness information
and an RFA bit. The RFA bit set to "1" indicates the Request for Acknowledge
condition. The Acknowledge condition is only applied when the protocol is
received correctly.
Bit sream : D0-D8 | 0 | RFA | 0 | A0-A7
Please refer to the links below for more details.
http://www.ti.com/lit/ds/symlink/tps61163.pdf
EasyScale on TPS61158/61/65
A command consists of 16 bits, including an 8-bit device address byte
and a 8-bit data byte. All of the 16 bits should be transmitted together
each time, and the MSB bit should be transmitted first. The device address
byte A7(MSB)~A0(LSB) is fixed (tps61158 0x58 tps61161 and tps61165 0x72).
The data byte includes an RFA bit.
The RFA bit set to "1" indicates the Request for Acknowledge condition.
The Acknowledge condition is only applied when the protocol is received
correctly.
Bit sream : A7-A0 | RFA | 00 | D4-D0
Please refer to the links below for more details.

[RFC v5 1/2] backlight: add new tps611xx backlight driver
This driver is a general version for tps611xx backlgiht chips of TI.
It supports tps61158, tps61161, tps61163 and tps61165 backlight driver
based on EasyScale protocol(1-Wire Control Interface).
EasyScale
EasyScale is a simple but flexible one pin interface to configure the current.
The interface is based on a master-slave structure, where the master is
typically a microcontroller or application processor and the IC is the slave.
The advantage of EasyScale compared with other one pin interfaces is that
its bit detection is in a large extent independent from the bit transmission
rate. It can automatically detect bit rates between 1.7kBit/sec and up
to 160kBit/sec.
EasyScale on TPS61163
A command consists of 24 bits, including an 8-bit device address byte and
a 16-bit data byte. All of the 24 bits should be transmitted together each
time, and the LSB bit should be transmitted first. The device address byte
A7(MSB)~A0(LSB) is fixed to 0x8F.
The data byte includes 9 bits D8(MSB)~D0(LSB) for brightness information
and an RFA bit. The RFA bit set to "1" indicates the Request for Acknowledge
condition. The Acknowledge condition is only applied when the protocol is
received correctly.
Bit sream : D0-D8 | 0 | RFA | 0 | A0-A7
Please refer to the links below for more details.
http://www.ti.com/lit/ds/symlink/tps61163.pdf
EasyScale on TPS61158/61/65
A command consists of 16 bits, including an 8-bit device address byte
and a 8-bit data byte. All of the 16 bits should be transmitted together
each time, and the MSB bit should be transmitted first. The device address
byte A7(MSB)~A0(LSB) is fixed (tps61158 0x58 tps61161 and tps61165 0x72).
The data byte includes an RFA bit.
The RFA bit set to "1" indicates the Request for Acknowledge condition.
The Acknowledge condition is only applied when the protocol is received
correctly.
Bit sream : A7-A0 | RFA | 00 | D4-D0
Please refer to the links below for more details.

[RFC v4 1/2] backlight: add new tps611xx backlight driver
This driver is a general version for tps611xx backlgiht chips of TI.
It supports tps61158, tps61161, tps61163 and tps61165 backlight driver
based on EasyScale protocol(1-Wire Control Interface).
EasyScale
EasyScale is a simple but flexible one pin interface to configure the current.
The interface is based on a master-slave structure, where the master is
typically a microcontroller or application processor and the IC is the slave.
The advantage of EasyScale compared with other one pin interfaces is that
its bit detection is in a large extent independent from the bit transmission

A7(MSB)~A0(LSB) is fixed to 0x8F.
The data byte includes 9 bits D8(MSB)~D0(LSB) for brightness information

EasyScale on TPS61158/61/65
A command consists of 16 bits, including an 8-bit device address byte
and a 8-bit data byte. All of the 16 bits should be transmitted together
each time, and the MSB bit should be transmitted first. The device address
byte A7(MSB)~A0(LSB) is fixed (tps61158 0x58 tps61161 and tps61165 0x72).
The data byte includes an RFA bit.

[RFC v2 1/2] backlight: add new tps611xx backlight driver
This driver a general version for tps611xx backlgiht chips of TI.
It supports tps61158, tps61161, tps61163 and tps61165 backlight driver
based on EasyScale protocol(1-Wire Control Interface).
EasyScale
EasyScale is a simple but flexible one pin interface to configure the current.
The interface is based on a master-slave structure, where the master is
typically a microcontroller or application processor and the IC is the slave.
The advantage of EasyScale compared with other one pin interfaces is that
its bit detection is in a large extent independent from the bit transmission
rate.
It can automatically detect bit rates between 1.7kBit/sec and up to 160kBit/sec.
EasyScale on TPS61163
A command consists of 24 bits, including an 8-bit device address byte and a
16-bit data byte.
All of the 24 bits should be transmitted together each time, and the LSB bit
should be
transmitted first. The device address byte A7(MSB)~A0(LSB) is fixed to 0x8F.
The data byte includes 9 bits D8(MSB)~D0(LSB) for brightness information and an
RFA bit.
The RFA bit set to 1 indicates the Request for Acknowledge condition. The
Acknowledge
condition is only applied when the protocol is received correctly.
Bit sream : D0-D8 | 0 | RFA | 0 | A0-A7
Please refer http://www.ti.com/lit/ds/symlink/tps61163.pdf for more details.
EasyScale on TPS61158/61/65
A command consists of 16 bits, including an 8-bit device address byte and a
8-bit data byte.
All of the 16 bits should be transmitted together each time, and the MSB bit
should be
transmitted first. The device address byte A7(MSB)~A0(LSB) is fixed (tps61158
0x58
tps61161 and tps61165 0x72). The data byte includes an RFA bit.
The RFA bit set to 1 indicates the Request for Acknowledge condition. The
Acknowledge
condition is only applied when the protocol is received correctly.
Bit sream : A7-A0 | RFA | 00 | D4-D0
Please refer the links below for more details.

I object adding a new fault which is essentially the same as an existing
fault, V4L2_FLASH_FAULT_OVER_TEMPERATURE.
I hope you consider it again.
Usually, when the die temperature exceeds the specific temperature, ie 120 or
135 and fixed value,
turn off PFET,NFET, current sources and set TEMP Fault bit.
But in the NTC mode, the comparator is working and detect selected temperature
through Vtrip value.
It protects shutdown the chip due to high voltage and keep the device operation.
Many flash chip support NTC and TEMP Fault both. For example, LM3554, LM3556,
LM3559
LM3642, LM3646, LM3560, LM3561, LM3565 etc
Two things should be tell apart.
As the practice has been to use human-readable names for the faults, I'd
also suggest using V4L2_FLASH_FAULT_UNDER_VOLTAGE instead of
V4L2_FLASH_FAULT_UVLO.
I agree with you.
What's the IVFM block and what does it do?
IVFM is Input Voltage Flash Monitor.
If the flash chip has IVFM function the flash current can be adjusted based
upon the voltage level of input.
As ramping flash current, the input voltage goes down and IVFM block adjust
current to prevent to shudown due to low voltage
and keep the flash operation. So if the input voltage crossed the IVFM
Threshold level chip set the fault bit.
Many flash chip, for example LM3556, LM3646, LM3642 , support this fucntion.
I think, V4L2_FLASH_FAULT_INPUT_VOLTAGE_MONITOR is better than
V4L2_FLASH_FAULT_IVFM.

As ramping flash current, the input voltage goes down and IVFM block adjust
current to prevent to shudown due to low voltage
and keep the flash operation. So if the input voltage crossed the IVFM
Threshold level chip set the fault bit.
Many flash chip, for example LM3556, LM3646, LM3642 , support this fucntion.
I think, V4L2_FLASH_FAULT_INPUT_VOLTAGE_MONITOR is better than
V4L2_FLASH_FAULT_IVFM.
#define V4L2_CID_FLASH_CHARGE (V4L2_CID_FLASH_CLASS_BASE + 11)
#define V4L2_CID_FLASH_READY (V4L2_CID_FLASH_CLASS_BASE + 12)

[RFCv2,2/2] i2c: add new dual Flash driver,LM3646
Add new dual flash driver.
LM3646 is a dual Flash LED Driver, LED1 and LED2, following the datasheet.
But there is no registers to contorl LED2 brightness.
LED2 brightness can be controlled by limiting max brightness.
LED2 brightness = Total brightness - LED1 brightness
LED2 will be off if LED2 brightness is set equal to or bigger than Total
brightness.
And the brightness step is very small, 1.46mA for Torch, 11.71mA for Flash.
If the step is changed to mA, maximum brightness cannot be reachable.

[PATCH V2] media: i2c: add driver for dual LED Flash, lm3560.
Patch v2 deletes unnecessary codes.
This patch adds the driver for the LM3560, dual LED Flash The
LM3560 has two 1A constant current driver for high current
white LEDs. It is controlled via an I2C compatible
interface(up to 400kHz). Each flash brightness, torch
brightness and enable/disable can be controlled
independantly. But flash timeout and operation mode are shared.

[PATCH V2] media: i2c: add driver for dual LED Flash, lm3560.
Patch v2 deletes unnecessary codes.
This patch adds the driver for the LM3560, dual LED Flash The
LM3560 has two 1A constant current driver for high current
white LEDs. It is controlled via an I2C compatible
interface(up to 400kHz). Each flash brightness, torch
brightness and enable/disable can be controlled
independantly. But flash timeout and operation mode are shared.

[PATCH 2/2] Add new FLASH driver for lm3565 chip
This driver is a general version for LM3565 Flash Driver chip of TI.
LM3565 :
The LM3565 is a 4MHz fixed-frequency, current mode synchronous boost
