[PATCH V2 0/4] Transform Fintek PCIE driver from 8250 to MFD
The Fintek F81504/508/512 is a multi-function PCIE devices. IC function list: F81504: Max 2x8 GPIOs and max 4 serial ports port2/3 are multi-function F81508: Max 6x8 GPIOs and max 8 serial ports port2/3 are multi-function, port8/9/10/11 are gpio only F81512: Max 6x8 GPIOs and max 12 serial ports port2/3/8/9/10/11 are multi-function It had implemented in 8250_pci.c with basic serial port function. We want to complete it. Alan & Andy recommend us to rewrite and spilt our driver with MFD architecture. https://lkml.org/lkml/2016/1/19/288 Paul recommed us do less code deletion to avoid confusing problem when bisect. https://lkml.org/lkml/2016/1/18/646 So we'll do this with following patches. 1. Add MFD core driver. 2. Add GPIOLIB driver. 3. Add serial port driver. 4. Remove old driver in 8250_pci.c It can be workable when applied patches 1~3. After apply patch 4, the device will control by F81504 MFD core driver.
