2023-02-28mips: dts: ralink: mt7621: add phandle to system controller node for watchdogSergio Paracuellos
To allow to access system controller registers from watchdog driver code add a phandle in the watchdog 'wdt' node. This avoid using arch dependent operations in driver code.

2023-02-28mips: dts: ralink: mt7621: rename watchdog node from 'wdt' into 'watchdog'Sergio Paracuellos
Watchdog nodes must use 'watchdog' for node name. When a 'make dtbs_check' is performed the following warning appears: wdt@100: $nodename:0: 'wdt@100' does not match '^watchdog(@.*|-[0-9a-f])?$' Fix this warning up properly renaming the node into 'watchdog'.

2023-02-27mips: ralink: make SOC_MT7621 select PINCTRLArınç ÜNAL
Currently, out of every Ralink SoC, only the dt-binding of the MT7621 SoC uses pinctrl. Because of this, PINCTRL is not selected at all. Make SOC_MT7621 select PINCTRL. Remove PINCTRL_MT7621, enabling it for the MT7621 SoC will be handled under the PINCTRL_MT7621 option.

2023-02-27MIPS: cevt-r4k: Offset the value used to clear compare interruptJiaxun Yang
In c0_compare_int_usable we clear compare interrupt by write value just read out from counter to compare register. However sometimes if those all instructions are graduated together then it's possible that at the time compare register is written, the counter haven't progressed, thus the interrupt is triggered again. It also applies to QEMU that instructions is executed significantly faster then counter. Offset the value used to clear interrupt by one to prevent that happen.

CP0_CMGCRBASE is not always available on CPS enabled system such as early proAptiv. For early SMP bring up where we can't safely access memeory, we patch the entry of CPS NMI vector to inject CMGCR address directly into register during early core bringup. For VPE bringup as the core is already coherenct at that point we just read the variable to obtain the address.

When neither LANTIQ nor MIPS_MALTA is set, 'physical_memsize' is not declared. This causes the build to fail with: mips-linux-ld: arch/mips/kernel/vpe-mt.o: in function `vpe_run': arch/mips/kernel/vpe-mt.c:(.text.vpe_run+0x280): undefined reference to `physical_memsize' LANTIQ is not using 'physical_memsize' and MIPS_MALTA's use of it is self-contained in mti-malta/malta-dtshim.c.

2022-12-30drm/i915/dsi: add support for ICL+ native MIPI GPIO sequenceJani Nikula
Starting from ICL, the default for MIPI GPIO sequences seems to be using native GPIOs i.e. GPIOs available in the GPU. These native GPIOs reuse many pins that quite frankly seem scary to poke based on the VBT sequences. We pretty much have to trust that the board is configured such that the relevant HPD, PP_CONTROL and GPIO bits aren't used for anything else. MIPI sequence v4 also adds a flag to fall back to non-native sequences. v5: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock() in icp_irq_handler() too (Ville) - References instead of Closes issue 6131 because this does not fix everything v4: - Wrap SHOTPLUG_CTL_DDI modification in spin_lock_irq() (Ville) v3: - Fix -Wbitwise-conditional-parentheses (kernel test robot <lkp@intel.com>) v2: - Fix HPD pin output set (impacts GPIOs 0 and 5) - Fix GPIO data output direction set (impacts GPIOs 4 and 9) - Reduce register accesses to single intel_de_rwm() References: https://gitlab.freedesktop.org/drm/intel/-/issues/6131 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221219105955.4014451-1-jani.nikula@intel.com (cherry picked from commit f087cfe6fcff58044f7aa3b284965af47f472fb0) Cc: stable@vger.kernel.org # 6.1 Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2022-12-30kbuild: rpm-pkg: add libelf-devel as alternative for BuildRequiresMasahiro Yamada
Guoqing Jiang reports that openSUSE cannot compile the kernel rpm due to "BuildRequires: elfutils-libelf-devel" added by commit 8818039f959b ("kbuild: add ability to make source rpm buildable using koji"). The relevant package name in openSUSE is libelf-devel. Add it as an alternative package. BTW, if it is impossible to solve the build requirement, the final resort would be: $ make RPMOPTS=--nodeps rpm-pkg This passes --nodeps to the rpmbuild command so it will not verify build dependencies. This is useful to test rpm builds on non-rpm system. On Debian/Ubuntu, for example, you can install rpmbuild by 'apt-get install rpm'. NOTE1: Likewise, it is possible to bypass the build dependency check for debian package builds: $ make DPKG_FLAGS=-d deb-pkg NOTE2: The 'or' operator is supported since RPM 4.13. So, old distros such as CentOS 7 will break. I suggest installing newer rpmbuild in such cases.

2022-12-30kbuild: Fix running modpost with musl libcSamuel Holland
commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.

2022-12-30arch: fix broken BuildID for arm64 and riscvMasahiro Yamada
Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1697b ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf4421 ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

2022-12-30drm/i915/uc: Fix two issues with over-size firmware filesJohn Harrison
In the case where a firmware file is too large (e.g. someone downloaded a web page ASCII dump from github...), the firmware object is released but the pointer is not zerod. If no other firmware file was found then release would be called again leading to a double kfree. Also, the size check was only being applied to the initial firmware load not any of the subsequent attempts. So move the check into a wrapper that is used for all loads.

2022-12-30drm/i915: improve the catch-all evict to handle lock contentionMatthew Auld
The catch-all evict can fail due to object lock contention, since it only goes as far as trylocking the object, due to us already holding the vm->mutex. Doing a full object lock here can deadlock, since the vm->mutex is always our inner lock. Add another execbuf pass which drops the vm->mutex and then tries to grab the object will the full lock, before then retrying the eviction. This should be good enough for now to fix the immediate regression with userspace seeing -ENOSPC from execbuf due to contended object locks during GTT eviction. v2 (Mani) - Also revamp the docs for the different passes.
