mfd: ioc3: Add driver for SGI IOC3 chip

2020-01-09T23:30:59+00:00

SGI IOC3 chip has integrated ethernet, keyboard and mouse interface. It also supports connecting a SuperIO chip for serial and parallel interfaces. IOC3 is used inside various SGI systemboards and add-on cards with different equipped external interfaces. Support for ethernet and serial interfaces were implemented inside the network driver. This patchset moves out the not network related parts to a new MFD driver, which takes care of card detection, setup of platform devices and interrupt distribution for the subdevices.

MIPS: SGI-IP27: No need for slice_map

2020-01-09T23:30:07+00:00

per_cpu_init is called exactly once for every CPU. So there is no need for protection via slice_map. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Store cpu speed when scanning for CPUs and use it later

2020-01-09T23:30:06+00:00

Remember CPU speed while scanning for available CPUs to avoid looking it up a second time when printing CPU speed. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Only reserve interrupts used in Linux

2020-01-09T23:30:04+00:00

Reduce number of reserved interrupts by removing bits copied from IRIX and not used by Linux. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Move all shared IP27 declarations to ip27-common.h

2020-01-09T23:30:03+00:00

Move all IP27 declarations into one file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Use specific get_region_shift

2020-01-09T23:30:01+00:00

IP35 has a different way to find out regions, so we move the IP27 implementation to IP27 specific file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Use structs for decoding error status registers

2020-01-09T23:29:59+00:00

Convert printing of error status registers to use structs, which are defines for IP27 and IP35. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: Use union instead of typedef

2020-01-09T23:29:58+00:00

The upcoming header files for SGI-IP35 shouldn't add new typedef. To be able to share ip27-hubio.c we need to access register layouts no longer via a typedef.

MIPS: SGI-IP27: Move get_nasid() to a IP27 specific file

2020-01-09T23:29:54+00:00

get_nasid() will be different for SGI-IP35, therefore move IP27 implementation to IP27 specific file. Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org

MIPS: SGI-IP27: get rid of asm/sn/sn0/ip27.h

The only piece needed in ip27.h is SEND_NMI. Move the define to the only place where it's used and remove ip27.h Signed-off-by: Thomas Bogendoerfer Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org
