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 v12: - added support for mapping all PCI interrupts as ioc3 uses INTB, if both ethernet and superio is used Changes in v11: - dropped accepted patches out of the series - moved byte swapping patch first in series - added ip30 system board support Changes in v10: - generation of fake subdevice ID had vendor and device ID swapped Changes in v9: - remove generated MFD devices, when driver is removed or in case of a mfd device setup error - remove irq domain, if setup of mfd devices failed - pci_iounmap on exit/error cases - added irq domain unmap function Changes in v8: - Re-worked comments in drivers/mfd/ioc3.c - Added select CRC16 to ioc3-eth.c - Patches 1 and 2 are already taken to mips-next, but for completeness of the series they are still included. What's missing to get the remaining 3 patches via the MIPS tree is an ack from a network maintainer 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 Thomas Bogendoerfer (3): MIPS: PCI: Support mapping of INTB/C/D for pci-xtalk-bridge MIPS: SGI-IP27: fix readb/writeb addressing mfd: ioc3: Add driver for SGI IOC3 chip arch/mips/include/asm/mach-ip27/mangle-port.h | 4 +- arch/mips/include/asm/pci/bridge.h | 3 +- arch/mips/include/asm/sn/ioc3.h | 38 +- arch/mips/pci/pci-xtalk-bridge.c | 28 +- arch/mips/sgi-ip27/ip27-timer.c | 20 - drivers/mfd/Kconfig | 13 + drivers/mfd/Makefile | 1 + drivers/mfd/ioc3.c | 669 ++++++++++++++++++ drivers/net/ethernet/sgi/Kconfig | 5 +- drivers/net/ethernet/sgi/ioc3-eth.c | 544 +++----------- drivers/rtc/rtc-m48t35.c | 11 + drivers/tty/serial/8250/8250_ioc3.c | 98 +++ drivers/tty/serial/8250/Kconfig | 11 + drivers/tty/serial/8250/Makefile | 1 + 14 files changed, 951 insertions(+), 495 deletions(-) create mode 100644 drivers/mfd/ioc3.c create mode 100644 drivers/tty/serial/8250/8250_ioc3.c -- 2.24.1
