2021-06-04ARM: dts: aspeed-g5: Add SCU phandle to GFX nodeJoel Stanley
In v5.13 the DRM driver gained support for using a phandle to the SCU, instead of matching on the scu compatible. Link: https://lore.kernel.org/r/20210603064536.165297-1-joel@jms.id.au Signed-off-by: Joel Stanley <joel@jms.id.au>
2021-04-09ARM: dts: Remove LPC BMC and Host partitionsChia-Wei, Wang
The LPC controller has no concept of the BMC and the Host partitions. A concrete instance is that the HICRB[5:4] are for the I/O port address configurtaion of KCS channel 1/2. However, the KCS driver cannot access HICRB for channel 1/2 initialization via syscon regmap interface due to the parition boundary. (i.e. offset 80h) In addition, for the HW design backward compatibility, a newly added HW control bit could be located at any reserved one over the LPC addressing space. Thereby, this patch removes the lpc-bmc and lpc-host child node and thus the LPC partitioning. Note that this change requires the synchronization between device tree change and the driver change. To prevent the misuse of old devicetrees with new drivers, or vice versa, the v2 compatible strings are adopted for the LPC device as listed: "aspeed,ast2400-lpc-v2" "aspeed,ast2500-lpc-v2" "aspeed,ast2600-lpc-v2" Signed-off-by: Chia-Wei Wang <chiawei_wang@aspeedtech.com> Reviewed-by: Andrew Jeffery <andrew@aj.id.au> Link: https://lore.kernel.org/r/20210319062752.145730-2-andrew@aj.id.au Signed-off-by: Joel Stanley <joel@jms.id.au>

2020-09-09ARM: aspeed: g5: Do not set sirq polarityJoel Stanley
A feature was added to the aspeed vuart driver to configure the vuart interrupt (sirq) polarity according to the LPC/eSPI strapping register. Systems that depend on a active low behaviour (sirq_polarity set to 0) such as OpenPower boxes also use LPC, so this relationship does not hold. Jeremy confirms that the s2600st which is strapped for eSPI also does not have this relationship. The property was added for a Tyan S7106 system which is not supported in the kernel tree. Should this or other systems wish to use this feature of the driver they should add it to the machine specific device tree.

There is a random number generator that updates a register in the SCU every second. This is compatible with the timeriomem rng driver in the kernel. From the timeriomem_rng bindings: quality: estimated number of bits of true entropy per 1024 bits read from the rng. Defaults to zero which causes the kernel's default quality to be used instead. Note that the default quality is usually zero which disables using this rng to automatically fill the kernel's entropy pool.

There is an ongoing set of dtc warning fixes and the usual bugfixes, cleanups and added device support. The most interesting bit as usual is support for new machines listed below: - The Allwinner H6 makes its debut with the Pine-H64 board, and we get two new machines based on its older siblings: the H5 based OrangePi Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side, we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2 Zero development board (based on H2). - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972 development board and p2888 CPU module. - The Nuvoton npcm750 is a BMC that was newly added, for now we only support running on the evaluation board. - STmicroelectronics stm32 gains support for the stm32mp157c and two evaluation boards. - The Toradex Colibri board family grows a few members based on the i.MX6ULL variant. - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6 family of chips. - The Phytec phyBOARD Mira is a family of industrial boards based on i.MX6. For now, four models get added. - TI am335x based PDU-001 is an industrial embedded machine used for traffic monitoring - The Aspeed platform now supports running on the BMC on the Qualcomm Centriq 2400 server - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm msm8974 based Galaxy S5 is a rather different phone made by the same company. - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file for the various boards made by Xilinx themselves, as well as the Digilent Zybo Z7. - The ARM Versatile family now supports the "IB2" interface board. - The Renesas H2 based "Stout" and the H3 based Salvator-X are more evaluation boards named after a kind of beer, as most of them are. The r8a77980 (V3H) based "Condor" apparently doesn't follow that tradition. ;-) - ROC-RK3328-CC is a simple developement board from the Libre Computer Project, based on the Rockchips RK3328 SoC - Haiku is another development board plus Qseven module based on Rockchips RK3368 and made by Theobroma Systems" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (701 commits) arm: dts: modify Nuvoton NPCM7xx device tree structure arm: dts: modify Makefile NPCM750 configuration name arm: dts: modify clock binding in NPCM750 device tree arm: dts: modify timer register size in NPCM750 device tree arm: dts: modify UART compatible name in NPCM750 device tree arm: dts: add watchdog device to NPCM750 device tree arm64: dts: uniphier: add ethernet node for PXs3 ARM: dts: uniphier: add pinctrl groups of ethernet for second instance arm: dts: kirkwood*.dts: use SPDX-License-Identifier for board using GPL-2.0+ arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0+/MIT arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0 arm: dts: armada-385-turris-omnia: use SPDX-License-Identifier arm: dts: armada-385-db-ap: use SPDX-License-Identifier arm: dts: armada-388-rd: use SPDX-License-Identifier arm: dts: armada-xp-db-xc3-24g4xg: use SPDX-License-Identifier arm: dts: armada-xp-db-dxbc2: use SPDX-License-Identifier arm: dts: armada-370-db: use SPDX-License-Identifier arm: dts: armada-*.dts: use SPDX-License-Identifier for most of the Armada based board arm: dts: armada-xp-98dx: use SPDX-License-Identifier for prestara 98d SoCs arm: dts: armada-*.dtsi: use SPDX-License-Identifier for most of the Armada SoCs ...
2018-03-14ARM: dts: aspeed: Add default memory nodeJoel Stanley
When we removed the inclusion of skeleton.dtsi from the device trees, we broke booting for systems with bootloaders that aren't device tre aware. This can be seen, for example, when appending the device tree blob to the kernel image. The reason booting broke was that the kernel lacked the device_type label in the memory node. Add in a default memory node wth the device_type. It can contain the memory address as the location is fixed for each SoC generation, but the size needs to be added by the bootloader or the board specific dts.
