Pull ARM SoC driver updates from Arnd Bergmann: "These are updates for drivers that are tied to a particular SoC, including the correspondig device tree bindings: - A couple of reset controller changes for unisoc, uniphier, renesas and zte platforms - memory controller driver fixes for omap and tegra - Rockchip io domain driver updates - Lots of updates for qualcomm platforms, mostly touching their firmware and power management drivers - Tegra FUSE and firmware driver updateѕ - Support for virtio transports in the SCMI firmware framework - cleanup of ixp4xx drivers, towards enabling multiplatform support and bringing it up to date with modern platforms - Minor updates for keystone, mediatek, omap, renesas" * tag 'drivers-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (96 commits) reset: simple: remove ZTE details in Kconfig help soc: rockchip: io-domain: Remove unneeded semicolon soc: rockchip: io-domain: add rk3568 support dt-bindings: power: add rk3568-pmu-io-domain support bus: ixp4xx: return on error in ixp4xx_exp_probe() soc: renesas: Prefer memcpy() over strcpy() firmware: tegra: Stop using seq_get_buf() soc/tegra: fuse: Enable fuse clock on suspend for Tegra124 soc/tegra: fuse: Add runtime PM support soc/tegra: fuse: Clear fuse->clk on driver probe failure soc/tegra: pmc: Prevent racing with cpuilde driver soc/tegra: bpmp: Remove unused including dt-bindings: soc: ti: pruss: Add dma-coherent property soc: ti: Remove pm_runtime_irq_safe() usage for smartreflex soc: ti: pruss: Enable support for ICSSG subsystems on K3 AM64x SoCs dt-bindings: soc: ti: pruss: Update bindings for K3 AM64x SoCs firmware: arm_scmi: Use WARN_ON() to check configured transports firmware: arm_scmi: Fix boolconv.cocci warnings soc: mediatek: mmsys: Fix missing UFOE component in mt8173 table routing soc: mediatek: mmsys: add MT8365 support ...

ARM: tegra: paz00: Handle device properties with software node API

2021-08-18T14:08:11Z

The old device property API is going to be removed. Replacing the device_add_properties() call with the software node API equivalent, device_create_managed_software_node().

soc/tegra: pmc: Prevent racing with cpuilde driver

2021-08-11T09:51:39Z

Both PMC and cpuidle drivers are probed at the same init level and cpuidle depends on the PMC suspend mode. Add new default suspend mode that indicates whether PMC driver has been probed and reset the mode in a case of deferred probe of the PMC driver.

ARM: tegra: Don't enable unused PLLs on resume from suspend

2021-01-19T17:20:42Z

PLLC and PLLM are usually disabled on system suspend because all devices which use these PLLs are either suspended or switched away to other clock source. Don't enable unused PLLs on resume from suspend by keeping track of the enable-state of the PLLs across suspend-resume.

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

mm: introduce include/linux/pgtable.h

2020-06-09T16:39:13Z

The include/linux/pgtable.h is going to be the home of generic page table manipulation functions. Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and make the latter include asm/pgtable.h.

ARM: tegra: Don't enable PLLX while resuming from LP1 on Tegra30

2020-05-06T16:50:52Z

PLLX may be kept disabled if cpufreq driver selects some other clock for CPU. In that case PLLX will be disabled later in the resume path by the CLK driver, which also can enable PLLX if necessary by itself. Thus there is no need to enable PLLX early during resume. Tegra114/124 CLK drivers do not manage PLLX on resume and thus they are left untouched by this patch.

ARM: tegra: Switch CPU to PLLP on resume from LP1 on Tegra30/114/124

2020-05-06T16:50:36Z

The early-resume code shall not switch CPU to PLLX because PLLX configuration could be unstable or PLLX should be simply disabled if CPU enters into suspend running off some other PLL (the case if CPUFREQ driver is active). The actual burst policy is restored by the clock drivers.
