Commit 54ff4a1d ("MIPS: Alchemy: pata_platform for DB1200") from year 2014 converted the only user of au1xxx-ide IDE host driver (MIPS Alchemy DB1200 platform) to use pata_platform libata host driver instead. This patch removes dead au1xxx-ide driver code. Acked-by:

Enable DMI scanning on the MIPS architecture, this setups DMI identifiers (dmi_system_id) for printing it out on task dumps and prepares DIMM entry information (dmi_memdev_info) from the SMBIOS table. With this patch, the driver can easily match various of mainboards. In the SMBIOS reference specification, the table anchor string "_SM_" is present in the address range 0xF0000 to 0xFFFFF on a 16-byte boundary, but there exists a special case for Loongson platform, when call function dmi_early_remap, it should specify the start address to 0xFFFE000 due to it is reserved for SMBIOS and can be normally access in the BIOS. This patch works fine on the Loongson 3A3000 platform which belongs to MIPS architecture and has no influence on the other architectures such as x86 and ARM. Additionally, in order to avoid the unknown risks on the mips platform which is not MACH_LOONGSON64, the DMI config is better to depend on MACH_LOONGSON64. If other mips platform also needs this DMI feature in the future, the "depends on" condition can be modified. Co-developed-by:

Use SMBIOS_ENTRY_POINT_SCAN_START instead of 0xF0000, because other archtecture maybe use a special start address such as 0xFFFE000 for Loongson platform. Signed-off-by:

mt7621 SoC has its own 'ralink_soc_info' structure with some information about the soc itself. Pcie controller and pcie phy drivers for this soc which are still in staging git tree make uses of 'soc_device_attribute' looking for revision 'E2' in order to know if reset lines are or not inverted. This way of doing things seems to be necessary in order to make things clean and properly. Hence, introduce this 'soc_device' to be able to properly use those attributes in drivers. Also set 'data' pointer points to the struct 'ralink_soc_info' to be able to export also current soc information using this mechanism.

We need the leds-gpio driver and enable the triggers. c) configure CONFIG_REGULATOR_ACT8865 for PMU The PMU on the CI20 board is an ACT8600 using the ACT8865 driver. Since it is not compiled, the PMU and the CI20 board is running in power-on reset state of the PMU. d) compile gpio-ir driver The CI20 board has a gpio based IR receiver. e) configure for CONFIG_KEYBOARD_GPIO=m The SW1 button is hooked up to send input events.

Some userland application/program runtime/dynamic loaded need to know about the current ISA level to use the best runtime. While kernel doesn't provides this info. ELF_PLATFORM only provides some info about the CPU, with very few info, for example, the value is "mips" for both 24Kc and P6600. Currently ELF_BASE_PLATFORM is not used by MIPS (only by powerpc). So we cant set its value as: mips2, mips3, mips4, mips5, mips32, mips32r2, mips32r6 mips64, mips64r2, mips64r6 Then in userland, we can get it by: getauxval(AT_BASE_PLATFORM) The only problem is that it seems has different defination than ppc: on ppc, it is the mircoarchitecture while now we use it as ISA level on MIPS.

Recently all usages of setup_irq() was replaced by request_irq(). request_irq() does a few sanity checks that were not done in setup_irq(), if they fail irq registration will fail. One of the check is to ensure that non-NULL dev_id is passed in the case of shared irq. This caused malta on qemu to hang. Fix it by passing handler as dev_id to all request_irq()'s that are shared. For sni, instead of passing non-NULL dev_id, remove shared irq flags. Fixes: ac8fd122 ("MIPS: Replace setup_irq() by request_irq()") Reported-by:

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot <lkp@intel.com> of which one was reported by Thomas Bogendoerfer <tsbogend@alpha.franken.de> as well. There were a few more issues including build errors, those also have been fixed. [1] https://lkml.kernel.org/r/alpine.DEB.2.20.1710191609480.1971@nanosSigned-off-by:

My time with MIPS the company has reached its end, and so at best I'll have little time spend on maintaining arch/mips/. Ralf last authored a patch over 2 years ago, the last time he committed one is even further back & activity was sporadic for a while before that. The reality is that he isn't active. Having a new maintainer with time to do things properly will be beneficial all round. Thomas Bogendoerfer has been involved in MIPS development for a long time & has offered to step up as maintainer, so add Thomas and remove myself & Ralf from the MIPS entry. Ralf already has an entry in CREDITS to honor his contributions, so this just adds one for me. Signed-off-by:
