The other patches are already merged, so I didn't resend them. They still apply as-is, so no changes are made. Changes from v2: * Collected acked-by. Original cover letter: This series add support for the Topwise A721 tablet and it's display. It is an old tablet (around 2012) but it might be useful as reference as the devicetree is pretty complete. Changes from v1: * Split into multiple patches * dt-binding: use yaml instead of txt * dt-binding: add Topwise A721 to sunxi.yaml * dt-binding: add Topwise to vendor-prefixes * drm: Add bus_format, bus_flags and connector_type * dts: Use SPDX license identifier instead of boilerplate license text * dts: Remove pinctrl leftovers Pascal Roeleven (2): dt-bindings: arm: Add Topwise A721 ARM: dts: sun4i: Add support for Topwise A721 tablet .../devicetree/bindings/arm/sunxi.yaml | 5 + arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/sun4i-a10-topwise-a721.dts | 242 ++++++++++++++++++ 3 files changed, 249 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/sun4i-a10-topwise-a721.dts -- 2.27.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel ^ permalink raw reply [flat|nested] 4+ messages in thread
