Enable the vpu-h1 clock when the domain is active because reading or writing to the VPU-H1 IP block cause the system to hang.

2021-11-21soc: imx: gpcv2: Synchronously suspend MIX domainsMarek Vasut
In case the following power domain sequence happens, iMX8M Mini always hangs: gpumix:on -> gpu:on -> gpu:off -> gpu:on This is likely due to another quirk of the GPC block. This situation can be prevented by always synchronously powering off both the domain and MIX domain. Make it so. This turns the aforementioned sequence into: gpumix:on -> gpu:on -> gpu:off -> gpumix:off -> gpumix:on -> gpu:on Signed-off-by: Marek Vasut <marex@denx.de> Cc: Frieder Schrempf <frieder.schrempf@kontron.de> Cc: Lucas Stach <l.stach@pengutronix.de> Cc: NXP Linux Team <linux-imx@nxp.com> Cc: Peng Fan <peng.fan@nxp.com> Cc: Shawn Guo <shawnguo@kernel.org> Acked-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

This set of changes introduces force_fatal_sig a way of sending a signal and not allowing it to be caught, and corrects the misuse of the existing abstractions that I found. A lot of the misuse of the existing abstractions are silly things such as doing something after calling a no return function, rolling BUG by hand, doing more work than necessary to terminate a kernel thread, or calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL). In the review a deficiency in force_fatal_sig and force_sig_seccomp where ptrace or sigaction could prevent the delivery of the signal was found. I have added a change that adds SA_IMMUTABLE to change that makes it impossible to interrupt the delivery of those signals, and allows backporting to fix force_sig_seccomp And Arnd found an issue where a function passed to kthread_run had the wrong prototype, and after my cleanup was failing to build." * 'exit-cleanups-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (23 commits) soc: ti: fix wkup_m3_rproc_boot_thread return type signal: Add SA_IMMUTABLE to ensure forced siganls do not get changed signal: Replace force_sigsegv(SIGSEGV) with force_fatal_sig(SIGSEGV) exit/r8188eu: Replace the macro thread_exit with a simple return 0 exit/rtl8712: Replace the macro thread_exit with a simple return 0 exit/rtl8723bs: Replace the macro thread_exit with a simple return 0 signal/x86: In emulate_vsyscall force a signal instead of calling do_exit signal/sparc32: In setup_rt_frame and setup_fram use force_fatal_sig signal/sparc32: Exit with a fatal signal when try_to_clear_window_buffer fails exit/syscall_user_dispatch: Send ordinary signals on failure signal: Implement force_fatal_sig exit/kthread: Have kernel threads return instead of calling do_exit signal/s390: Use force_sigsegv in default_trap_handler signal/vm86_32: Properly send SIGSEGV when the vm86 state cannot be saved. signal/vm86_32: Replace open coded BUG_ON with an actual BUG_ON signal/sparc: In setup_tsb_params convert open coded BUG into BUG signal/powerpc: On swapcontext failure force SIGSEGV signal/sh: Use force_sig(SIGKILL) instead of do_group_exit(SIGKILL) signal/mips: Update (_save|_restore)_fp_context to fail with -EFAULT signal/sparc32: Remove unreachable do_exit in do_sparc_fault ...

2021-10-15soc: qcom: rpmhpd: Make power_on actually enable the domainBjorn Andersson
The general expectation is that powering on a power-domain should make the power domain deliver some power, and if a specific performance state is needed further requests has to be made. But in contrast with other power-domain implementations (e.g. rpmpd) the RPMh does not have an interface to enable the power, so the driver has to vote for a particular corner (performance level) in rpmh_power_on(). But the corner is never initialized, so a typical request to simply enable the power domain would not actually turn on the hardware. Further more, when no more clients vote for a performance state (i.e. the aggregated vote is 0) the power domain would be turned off. Fix both of these issues by always voting for a corner with non-zero value, when the power domain is enabled. The tracking of the lowest non-zero corner is performed to handle the corner case if there's ever a domain with a non-zero lowest corner, in which case both rpmh_power_on() and rpmh_rpmhpd_set_performance_state() would be allowed to use this lowest corner.

The dpio driver exports new functions to enable/disable adaptive IRQ coalescing on a DPIO object, to query the state or to update Net DIM with a new set of bytes and frames dequeued.
