The Exynos 8895 SoC is also used in S8 Plus (dream2lte), Note 8 (greatlte) and Meizu 15 Plus (m1891). Currently DT is added for the Exynos 8895 SoC and dreamlte, but it should be really easy to adapt for the other devices with the same SoC. It has been tested with dtbs_check W=1 and results in no warnings. The support added in this series consists of: * cpus * pinctrl * gpio * simple-framebuffer * pstore This is enough to reach a minimal initramfs shell using an upstream kernel. More platform support will be added in the future. The preferred way to boot this device is by using a small shim bl called uniLoader [1], which packages the mainline kernel and DT and jumps to the kernel. This is done in order to work around some issues caused by the stock, and non-replacable Samsung S-Boot bootloader. For example, S-Boot leaves the decon trigger control unset, which causes the framebuffer to not refresh. [1] https://github.com/ivoszbg/uniLoader Changes in v2: - No patch changes were made, only fixed the issues with my git send-email Changes in v3: - Added a-b tags by Rob Herring and Linus Walleij - Ordered the Samsung Mongoose M2 compatible in cpus.yaml - Ordered the EXYNOS8895 information in exynos-chipid.c - Made the commit message for pinctrl support more detailed - Made the commit message for exynos-pmu.yaml more detailed - Fixed suffixes for the exynos8895 pinctrl device tree - Removed redundant nodes from the exynos8895 pinctrl device tree - Made the arm-a53-pmu node cover only the Cortex A53 cores - Added a comment mentioning the lack of a PMU model for Mongoose cores - Added a comment mentioning the issue with CNTFRQ_EL0 - Removed the redundant fixed rate clocks wrapper - Ordered the nodes by the DTS coding style in all 8895 DT files - Removed the redundant status property from the simple-framebuffer node - Switch to dual licensing (GPL-2.0 OR BSD-3-Clause) for the DT files Changes in v4: - Added r-b tag by Sam Protsenko - Resolved the remaining pinctrl node name regex issues - Corrected interrupt-cells for gpa1-gpio-bank - Fixed suffixes for the dreamlte gpio keys pin nodes - Reordered the dreamlte gpio-keys nodes alphabetically - Fixed interrupt-controller simple-bus unit address - Change framebuffer-related node labels to match other device trees Changes in v5: - Removed a false a-b - Added an r-b tag by Krzysztof Kozlowski - Ordered nodes alphabetically while keeping -gpio-bank's in front in the exynos8895 pinctrl DT - Sorted a few nodes and properties in the exynos8895 SoC DT Kind regards, Ivaylo.
