MIPS: ralink: mt7621: Fix soc_device introduction

2020-03-28T16:26:36+00:00

Depending on selected SMP config options soc_device didn't get initialised at all. With UP config vmlinux didn't link because of missing soc bus. Fixes: 71b9b5e0130d ("MIPS: ralink: mt7621: introduce 'soc_device' initialization") Signed-off-by: Thomas Bogendoerfer Tested-by: René van Dorst

MIPS: ralink: mt7621: introduce 'soc_device' initialization

2020-03-23T14:44:04+00:00

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.

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35+00:00

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 remove_irq() has been replaced by free_irq() as well.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 of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.

Pull MIPS changes from Paul Burton: "Nothing too big or scary in here: - Support mremap() for the VDSO, primarily to allow CRIU to restore the VDSO to its checkpointed location. - Restore the MIPS32 cBPF JIT, after having reverted the enablement of the eBPF JIT for MIPS32 systems in the 5.5 cycle. - Improve cop0 counter synchronization behaviour whilst onlining CPUs by running with interrupts disabled. - Better match FPU behaviour when emulating multiply-accumulate instructions on pre-r6 systems that implement IEEE754-2008 style MACs. - Loongson64 kernels now build using the MIPS64r2 ISA, allowing them to take advantage of instructions introduced by r2. - Support for the Ingenic X1000 SoC & the really nice little CU Neo development board that's using it. - Support for WMAC on GARDENA Smart Gateway devices. - Lots of cleanup & refactoring of SGI IP27 (Origin 2*) support in preparation for introducing IP35 (Origin 3*) support. - Various Kconfig & Makefile cleanups" * tag 'mips_5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: (60 commits) MIPS: PCI: Add detection of IOC3 on IO7, IO8, IO9 and Fuel MIPS: Loongson64: Disable exec hazard MIPS: Loongson64: Bump ISA level to MIPSR2 MIPS: Make DIEI support as a config option MIPS: OCTEON: octeon-irq: fix spelling mistake "to" -> "too" MIPS: asm: local: add barriers for Loongson MIPS: Loongson64: Select mac2008 only feature MIPS: Add MAC2008 Support Revert "MIPS: Add custom serial.h with BASE_BAUD override for generic kernel" MIPS: sort MIPS and MIPS_GENERIC Kconfig selects alphabetically (again) MIPS: make CPU_HAS_LOAD_STORE_LR opt-out MIPS: generic: don't unconditionally select PINCTRL MIPS: don't explicitly select LIBFDT in Kconfig MIPS: sync-r4k: do slave counter synchronization with disabled HW interrupts MIPS: SGI-IP30: Check for valid pointer before using it MIPS: syscalls: fix indentation of the 'SYSNR' message MIPS: boot: fix typo in 'vmlinux.lzma.its' target MIPS: fix indentation of the 'RELOCS' message dt-bindings: Document loongson vendor-prefix MIPS: CU1000-Neo: Refresh defconfig to support HWMON and WiFi. ...

MIPS: ralink: enable PCI support only if driver for mt7621 SoC is selected

2019-11-14T05:09:37+00:00

Some versions of SoC MT7621 have three PCI express hosts. Some boards make use of those PCI through the staging driver mt7621-pci. Recently PCI support has been removed from MT7621 Soc kernel configuration due to a build error. This makes imposible to compile staging driver and produces a regression for gnubee based boards. Enable support for PCI again but enable it only if staging mt7621-pci driver is selected.

MIPS: Remove dev_err() usage after platform_get_irq()

2019-08-26T10:26:04+00:00

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).
