2020-01-09dt-bindings: nvmem: new optional property wp-gpiosKhouloud Touil
Several memories have a write-protect pin, that when pulled high, it blocks the write operation. On some boards, this pin is connected to a GPIO and pulled high by default, which forces the user to manually change its state before writing. Instead of modifying all the memory drivers to check this pin, make the NVMEM subsystem check if the write-protect GPIO being passed through the nvmem_config or defined in the device tree and pull it low whenever writing to the memory. Add a new optional property to the device tree binding document, which allows to specify the GPIO line to which the write-protect pin is connected.

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 ...
