2021-12-16soc/tegra: pmc: Add reboot notifierJon Hunter
The Tegra PMC driver implements a restart handler that supports Tegra specific reboot commands such as placing the device into 'recovery' mode in order to reprogram the platform. This is accomplished by setting the appropriate bit in the PMC scratch0 register prior to rebooting the platform. For Tegra platforms that support PSCI or EFI, the default Tegra restart handler is not called and the PSCI or EFI restart handler is called instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra specific reboot commands do not currently work. Fix this by moving the code that programs the PMC scratch0 register into a separate reboot notifier that will always be called on reboot.

2021-12-16soc/tegra: Don't print error message when OPPs not availableDmitry Osipenko
Previously we assumed that devm_tegra_core_dev_init_opp_table() will be used only by drivers that will always have device with OPP table, but this is not true anymore. For example now Tegra30 will have OPP table for PWM, but Tegra20 not and both use the same driver. Hence let's not print the error message about missing OPP table in the common helper, we can print it elsewhere.

2021-12-08soc: xilinx: move PM_INIT_FINALIZE to zynqmp_pm_domains driverMichael Tretter
PM_INIT_FINALIZE tells the PMU FW that Linux is able to handle the power management nodes that are provided by the PMU FW. Nodes that are not requested are shut down after this call. Calling PM_INIT_FINALIZE from the zynqmp_power driver is wrong. The PM node request mechanism is implemented in the zynqmp_pm_domains driver, which must also call PM_INIT_FINALIZE. Due to the behavior of the PMU FW, all devices must be powered up before PM_INIT_FINALIZE is called, because otherwise the devices might misbehave. Calling PM_INIT_FINALIZE from the sync_state device callback ensures that all users probed successfully before the PMU FW is allowed to power off unused domains.

Reduce scanning to a single pass using of_find_matching_node_and_match() instead.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - Move the command line preparation and the early command line parsing earlier so that the command line parameters which affect early_reserve_memory(), e.g. efi=nosftreserve, are taken into account. This was broken when the invocation of early_reserve_memory() was moved recently. - Use an atomic type for the SGX page accounting, which is read and written locklessly, to plug various race conditions related to it. * tag 'x86-urgent-2021-11-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/sgx: Fix free page accounting x86/boot: Pull up cmdline preparation and early param parsing

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>

One item stand out and that is that I delete the <linux/sdb.h> header that is used by nothing. I deleted this subsystem (through the GPIO tree) a while back so I feel responsible for tidying up the floor.
