* libata: Assign OF node to the SCSI deviceLinus Walleij2020-03-251-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | When we spawn a SCSI device from an ATA device in libata-scsi the SCSI device had no relation to the device tree. The DT binding allows us to define port nodes under a PATA (IDE) or SATA host controller, so we can have proper device nodes for these devices. If OF is enabled, walk the children of the host controller node to see if there is a valid device tree node to assign. The reg is used to match to ID 0 for the master device and ID 1 for the slave device. The corresponding device tree bindings have been accepted by the device tree maintainers.

Largest delta is due to a led-bl driver that is added -- there was a miscommunication before the merge window and the driver didn't make it in. Due to this, the platforms needing it regressed. At this point, it seemed easier to add the new driver than unwind the changes. Besides that, there are a handful of various fixes: - AMD tee memory leak fix - A handful of fixlets for i.MX SCU communication - A few maintainers woke up and realized DEBUG_FS had been missing for a while, so a few updates of that. ... and the usual collection of smaller fixes to various platforms" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (37 commits) ARM: socfpga_defconfig: Add back DEBUG_FS arm64: dts: socfpga: agilex: Fix gmac compatible ARM: bcm2835_defconfig: Explicitly restore CONFIG_DEBUG_FS arm64: dts: meson: fix gxm-khadas-vim2 wifi arm64: dts: meson-sm1-sei610: add missing interrupt-names ARM: meson: Drop unneeded select of COMMON_CLK ARM: dts: bcm2711: Add pcie0 alias ARM: dts: bcm283x: Add missing properties to the PWR LED tee: amdtee: fix memory leak in amdtee_open_session() ARM: OMAP2+: Fix compile if CONFIG_HAVE_ARM_SMCCC is not set arm: dts: dra76x: Fix mmc3 max-frequency ARM: dts: dra7: Add "dma-ranges" property to PCIe RC DT nodes bus: ti-sysc: Fix 1-wire reset quirk ARM: dts: r8a7779: Remove deprecated "renesas, rcar-sata" compatible value soc: imx-scu: Align imx sc msg structs to 4 firmware: imx: Align imx_sc_msg_req_cpu_start to 4 firmware: imx: scu-pd: Align imx sc msg structs to 4 firmware: imx: misc: Align imx sc msg structs to 4 firmware: imx: scu: Ensure sequential TX ARM: dts: imx7-colibri: Fix frequency for sd/mmc ...
