2020-01-26hwrng: omap3-rom - Fix missing clock by probing with device treeTony Lindgren
[ Upstream commit 0c0ef9ea6f3f0d5979dc7b094b0a184c1a94716b ] Commit 0ed266d7ae5e ("clk: ti: omap3: cleanup unnecessary clock aliases") removed old omap3 clock framework aliases but caused omap3-rom-rng to stop working with clock not found error. Based on discussions on the mailing list it was requested by Tero Kristo that it would be best to fix this issue by probing omap3-rom-rng using device tree to provide a proper clk property. The other option would be to add back the missing clock alias, but that does not help moving things forward with removing old legacy platform_data. Let's also add a proper device tree binding and keep it together with the fix.

2019-09-05hwrng: timeriomem - relax check on memory resource sizeDaniel Mack
The timeriomem_rng driver only accesses the first 4 bytes of the given memory area and currently, it also forces that memory resource to be exactly 4 bytes in size. This, however, is problematic when used with device-trees that are generated from things like FPGA toolchains, where the minimum size of an exposed memory block may be something like 4k. Hence, let's only check for what's needed for the driver to operate properly; namely that we have enough memory available to read the random data from.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree updates from Olof Johansson: "As always, a large number of DT updates. Too many to enumerate them all, but at a glance: New SoCs introduced in this release: - Amlogic: + Meson 8M2 SoC, a.k.a. S812. A quad Cortex-A9 SoC used in some set top boxes and other products. - Mediatek: + MT7623A, which is a flavor of the MT7623 family with other on-chip ethernet options. - Qualcomm: + SDM845, a.k.a Snapdragon 845, an 4+4-core Kryo 385/845 (Cortex-A75/A55 derivative) SoC that's one of the current high-end mobile SoCs. It's great to see mainline support for it. So far, you can't do much with it, since a lot of peripherals are not yet in the DTs but driver support for USB, GPU and other pieces are starting to trickle in. This might end up being a well-supported SoC upstream if the momentum keeps up. - Renesas: + R8A77990, a.k.a R-Car E3, a new automotive entertainment-targeted SoC. Currently only one Cortex-A53 CPU is enabled, we are eagerly awaiting more. So far, basic drivers such as serial, gpios, PMU and ethernet are enabled. + R8A77470, a.k.a. RZ/G1C, a new dual Cortex-A7 SoC with PowerVR GPU. Same here, basic set of drivers such as serial, gpios and ethernet enabled, and SMP support is also forthcoming. - STMicroelectronics: + STM32F469, very similar tih STM32F429 but with display support Enhancements to SoCs/platforms (DTS contents, some driver portions might not be in yet): - Allwinner sun8i (h3/a33/a83t) SMP, DVFS tweaks, misc - Amlogic Meson: I2C, UFS, TDM, GPIO external interrupts, MMC resets - Hisilicon hi3660: Thermal cooling, CPU frequency scaling, mailbox interfaces - Marvell Berlin2CD: SMP support, thermal sensors - Mediatek MT7623: Highspeed DMA, audio support - Qualcomm IPQ8074 PCIe support, MSM8996 UFS support - Renesas: Watchdog and PMU support across many platforms - Rockchip RK3399: USB3 OTG support - Samsung Exynos: Audio-over-HDMI on Odroid X/X2/U3 - STMicro STM32: Lots of peripherals added to STM32MP175C - Uniphier: Ethernet support New boards: - Allwinner A20: Olimex A20-SOM-EVB-eMMC variant - Allwinner H2+: Libre Computer ALL-H3-CC (h2+ version) - Allwinner A33: Nintendo NES/SuperNES Classic Edition - Aspeed: S2600WF, Inventec Lanyang BMC, Portwell Neptune - Berlin2CD: Valve Steam Link - Broadcom BCM5301X: Luxul XAP-1610 and XWR-3150 V1 - Broadcom: Raspberry Pi 3 B+ - Mediatek MT7623N and MT7623A: reference boards - Meson 8M2: Tronsmart MXIII Plus - NXP i.MX: Engicam i.CoreM6, DHCOM iMX6 SOM, BTicino i.MX6DL Mamoj - Qualcomm MSM8974: Sony Xperia Z1 Compact support - Qualcomm SDM845: MTP development board - Renesas: Ebisu R8A77990 board - Renesas RZ/G1C: iwg23s: iWave G235-SDB - TI am335x: Pocketbeagle support" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (448 commits) ARM: dts: aspeed: Fix hwrng register address arm64: dts: sprd: whale2: Add the rtc enable clock for watchdog arm64: dts: sprd: Add GPIO and GPIO keys device nodes arm64: dts: sprd: fix typo in 'remote-endpoint' arm64: dts: apq8096-db820c: Removed bt-en-1-8v regulator arm64: dts: fix regulator property name for wlan pcie endpoint arm64: dts: qcom: msm8996: Use UFS_GDSC for UFS ARM: dts: pxa3xx: fix MMC clocks ARM: pxa: dts: add pin definitions for extended GPIOs ARM: pxa: dts: add gpio-ranges to gpio controller ARM: dts: ipq8074: Enable few peripherals for hk01 board ARM: dts: ipq8074: Add pcie nodes ARM: dts: ipq8074: Add peripheral nodes ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk07.1-c2 board file ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk07.1-c1 board file ARM: dts: ipq4019: Add ipq4019-ap.dk07.1 common data ARM: dts: ipq4019: Add qcom-ipq4019-ap.dk04.1-c3 board file ARM: dts: ipq4019: Add ipq4019-ap.dk04.1-c1 board file ARM: dts: ipq4019: Add ipq4019-ap.dk04.dtsi ARM: dts: ipq4019: Change the max opp frequency ...

Commit 52060836f79 ("dt-bindings: omap-rng: Document SafeXcel IP-76 device variant") update the omap_rng Device Tree binding to add support for the IP-76 variation of the IP. As part of this change, a "clocks" property was added, but is indicated as "Required", without indicated it's actually only required for some compatible strings. This commit fixes that, by explicitly stating that the clocks property is only required with the inside-secure,safexcel-eip76 compatible string.
