Hi everyone, This is v2 of the Allwinner A80 PRCM support series. Thanks to Allwinner updating their documents, we can now support the essential parts of the PRCM.
This series adds support for the Power Reset and Clock Management module on Allwinner's A80 SoC. The PRCM manages clocks and resets for the "special" block of peripherals, or the R/RTC block in earlier SoCs, as well as power domain and resets for various parts of the SoC, such as the 2 processor clusters, the GPU and others. The special peripherals include a standby processor core, a timer block, a watchdog, pin controller, 1 wire interface, PS/2 interface, a UART, the RSB controller, a DMA controller, a consumer IR receiver block, 2 I2C controllers, and 2 I2S controllers. We do not have documents for all the peripherals. Support will be added where possible. The first 2 patches add drivers for new clocks. The 3rd patch adds a compatible string and associated list of sub- devices to the prcm mfd driver. The 4th patch adds the PRCM device nodes to the A80 dtsi. The last patch adds some comments regarding the 2 system oscillators. Changes since v1: - Added missing clock gates based on updated documents - Added new cpus clock driver based on updated documents - Added pll3 clock placeholder - Added comments about 24M & 32k oscillators Regards ChenYu Chen-Yu Tsai (5): clk: sunxi: sun6i-apb0: Add support for sun9i A80 apbs gates clk: sunxi: support the cpus (cpu special) clock on the Allwinner A80 mfd: sun6i-prcm: Add support for PRCM found on Allwinner A80 SoC ARM: dts: sun9i: Add A80 PRCM clocks and reset control nodes ARM: dts: sun9i: Add TODO comments for the main and low power clocks Documentation/devicetree/bindings/clock/sunxi.txt | 2 + .../devicetree/bindings/mfd/sun6i-prcm.txt | 3 +- arch/arm/boot/dts/sun9i-a80.dtsi | 79 ++++++- drivers/clk/sunxi/Makefile | 2 +- drivers/clk/sunxi/clk-sun6i-apb0-gates.c | 5 + drivers/clk/sunxi/clk-sun9i-cpus.c | 243 +++++++++++++++++++++ drivers/mfd/sun6i-prcm.c | 58 +++++ 7 files changed, 389 insertions(+), 3 deletions(-) create mode 100644 drivers/clk/sunxi/clk-sun9i-cpus.c -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
