[PATCH v3 01/10] arm: sunxi: add support for R40 SoC

Allwinner R40 is a new SoC, with Quad Core Cortex-A7 and peripherals like A20. Add support for it. Signed-off-by: Icenowy Zheng --- Changes in v3: - Use V1.0 documents. Documentation/arm/sunxi/README | 6 ++ Documentation/devicetree/bindings/arm/sunxi.txt | 1 + arch/arm/m

[PATCH v3 00/10] Initial Allwinner R40 support

This is the first non-RFC version of this patchset, which added basical support including I2C, UART and MMC to the mainline Linux. The pinctrl driver of A20 is also merged into the one of A10 before R40 support is added into the A10 driver. Chen-Yu Tsai (2): ARM: dts: sun8i: Add basic dtsi file

[PATCH v3 04/10] pinctrl: sunxi: drop dedicated A20 driver

As we added A20 support to A10 pinctrl driver, now we can delete the dedicated A20 pinctrl driver, which is duplicated code. Signed-off-by: Icenowy Zheng --- Changes in v3: - Only remove the A20 driver(A10 driver for A20 is enabled in the previous commit now). drivers/pinctrl/sunxi/Kconfig

[PATCH v3 06/10] pinctrl: sunxi: add support of R40 to A10 pinctrl driver

R40 is said to be an upgrade of A20, and its pin configuration is also similar to A20 (and thus similar to A10). Add support for R40 to the A10 pinctrl driver. Signed-off-by: Icenowy Zheng --- drivers/pinctrl/sunxi/Kconfig | 2 +- drivers/pinctrl/sunxi/pinctrl-sun4i-a10.c | 272 ++

[PATCH v3 03/10] pinctrl: sunxi: add A20 support to A10 driver

As A20 is designed as a pin-compatible upgrade of A10, their pin controller are very similar, and can share one driver. Add A20 support to the A10 driver. Signed-off-by: Icenowy Zheng --- Changes in v3: - Enable A10 driver for A20 and disable A20 driver in this commit, in order to prevent A10

[PATCH v3 08/10] clk: sunxi-ng: support R40 SoC

Allwinner R40 SoC have a clock controller module in the style of the SoCs beyond sun6i, however, it's more rich and complex. Add support for it. Signed-off-by: Icenowy Zheng --- Changes in v3: - Rebased on current linux-next. Changes in v2: - Fixes according to the SoC's user manual. drivers/c

[PATCH v3 10/10] ARM: dts: sun8i: Add board dts file for Banana Pi M2 Ultra

From: Chen-Yu Tsai The Banana Pi M2 Ultra is an SBC based on the Allwinner R40 SoC. The form factor and position of various connectors, leds and buttons is similar to the Banana Pi M1+, Banana Pi M3, and is exactly the same as the latest Banana Pi M64. It features: - X-Powers AXP221s PMIC con

[PATCH v3 07/10] dt-bindings: add compatible string for Allwinner R40 CCU

Allwinner R40 has a clock controlling unit like the ones on other Allwinner SoCs after sun6i, and can also use a CCU-based driver. Add a compatible string for it. Signed-off-by: Icenowy Zheng Acked-by: Rob Herring --- Changes in v3: - Rebased on current linux-next. - Added Rob's ACK. Document

[PATCH v3 02/10] pinctrl: sunxi: Add SoC ID definitions for A10, A20 and R40 SoCs

Allwinner A10, A20 and R40 SoCs have similar GPIO layout. Add SoC definitions in pinctrl-sunxi.h, in order to merge A20 support into A10 driver, and add R40 support into it. Signed-off-by: Icenowy Zheng --- Changes in v3: - Commit message change. drivers/pinctrl/sunxi/pinctrl-sunxi.h | 3 +++

[PATCH v3 05/10] dt-bindings: add compatible string for Allwinner R40 pinctrl

Allwinner R40 has a pin controller like the ones in older Allwinner SoCs (especially A20), and can use modified version of the A10/A20 pinctrl driver. Add a compatible string for it. Signed-off-by: Icenowy Zheng Acked-by: Rob Herring --- Changes in v3: - Added Rob's ACK. Documentation/devicet

[PATCH v3 09/10] ARM: dts: sun8i: Add basic dtsi file for Allwinner R40

From: Chen-Yu Tsai The Allwinner R40 SoC is marketed as the successor to the A20 SoC. The R40 is a smaller chip than the A20, but features the same set of programmable pins, with a couple extra pins and some new pin functions. The chip features 4 Cortex-A7 cores and a Mali-400 MP2 GPU. It retains
