Subject: [PATCH V2 0/4] Transform Fintek PCIE driver from 8250 to MFD
Date: Thu, 28 Jan 2016 17:20:34 +0800	[thread overview]
Message-ID: <1453972838-30268-1-git-send-email-hpeter+linux_kernel@gmail.com> (raw)

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.
