Subject: [PATCH v5 00/17] Use MFD framework for SGI IOC3 drivers
Date:   Mon, 19 Aug 2019 18:31:23 +0200
Message-Id: <20190819163144.3478-1-tbogendoerfer@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

GI IOC3 ASIC includes support for ethernet, PS2 keyboard/mouse,
NIC (number in a can), GPIO and a byte  bus. By attaching a
SuperIO chip to it, it also supports serial lines and a parallel
port. The chip is used on a variety of SGI systems with different
configurations. This patchset moves code out of the network driver,
which doesn't belong there, into its new place a MFD driver and
specific platform drivers for the different subfunctions.

Changes in v5:
 - requested by Jakub I've splitted ioc3 ethernet driver changes into
   more steps to make the transition more visible; on the way there 
   I've "checkpatched" the driver and reduced code reorderings
 - dropped all uint16_t and uint32_t
 - added nvmem API extension to the documenation file
 - changed to use request_irq/free_irq in serio driver
 - removed wrong kfree() in serio error path

Changes in v4:
 - added w1 drivers to the series after merge in 5.3 failed because
   of no response from maintainer and other parts of this series
   won't work without that drivers
 - moved ip30 systemboard support to the ip30 series, which will
   deal with rtc oddity Lee found
 - converted to use devm_platform_ioremap_resource
 - use PLATFORM_DEVID_AUTO for serial, ethernet and serio in mfd driver
 - fixed reverse christmas order in ioc3-eth.c
 - formating issue found by Lee
 - re-worked irq request/free in serio driver to avoid crashes during
   probe/remove

Changes in v3:
 - use 1-wire subsystem for handling proms
 - pci-xtalk driver uses prom information to create PCI subsystem
   ids for use in MFD driver
 - changed MFD driver to only use static declared mfd_cells
 - added IP30 system board setup to MFD driver
 - mac address is now read from ioc3-eth driver with nvmem framework

Changes in v2:
 - fixed issue in ioc3kbd.c reported by Dmitry Torokhov
 - merged IP27 RTC removal and 8250 serial driver addition into
   main MFD patch to keep patches bisectable
