The Fintek F81532A/534A/535/536 is USB-to-2/4/8/12 serial ports device
and the serial port is default disabled when plugin computer.
The part number is a bit same with F81532/534, but F81534A series UART
core is enhanced from F81232, not F81532/534.
The IC is contains devices as following:
1. HUB (all devices is connected with this hub)
2. GPIO/Control device. (enable serial port and control all GPIOs)
but this series patch not implement GPIO control.
3. serial port 1 to x (2/4/8/12)
It's most same with F81232, the UART device is difference as follow:
1. TX/RX bulk size is 128/512bytes
2. RX bulk layout change:
F81232: [LSR(1Byte)+DATA(1Byte)][LSR(1Byte)+DATA(1Byte)]...
F81534A:[LEN][Data.....][LSR]
We'll try to do some code refacting before add F81534A series.
Ji-Ze Hong (Peter Hong) (6):
USB: serial: f81232: Extract LSR handler
USB: serial: f81232: Add tx_empty function
USB: serial: f81232: Use devm_kzalloc
USB: serial: f81232: Add F81534A support
USB: serial: f81232: Set F81534A serial port with RS232 mode
USB: serial: f81232: Add generator for F81534A
