Subject: [PATCH v7 0/5] Use MFD framework for SGI IOC3 drivers
Date: Thu, 3 Oct 2019 11:52:28 +0200 [thread overview]
Message-ID: <20191003095235.5158-1-tbogendoerfer@suse.de> (raw)
SGI 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 v7:
- added patch to enable ethernet phy for Origin 200 systems
- depend on 64bit for ioc3 mfd driver
Changes in v6:
- dropped patches accepted for v5.4-rc1
- moved serio patch to ip30 patch series
- adapted nvmem patch
Changes in v5:
- requested by Jakub I've splited 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
