    Subject[PATCH v2 00/10] ARM: sunxi: Introduce Allwinner H3 support
    Date
    Hi everyone,

    This is v2 of my patch series introducing basic kernel support for Allwinner's
    H3 SoC. It mainly adds basic clocks and pinctrl. It also adds interrupts,
    timers, watchdog, RTC, dmaengine, MMC and UARTs, which are mostly compatible
    to those in earlier SoCs like A23 and A31, and can simply be reused.

    These patches are based on Maxime's sunxi/for-next branch from
    git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git


    The first four patches are documentation updates and generic changes to the
    sunxi clock and pinctrl drivers, preparing them for the H3 addition.

    Patch 1 updates the sunxi README with new SoCs, including the H3

    Patch 2 adds support for multiple parents to the sunxi gates clock, needed
    for the new bus gates in H3

    Patch 3 improves the sunxi divs clock to read the name of the base factor clock
    from devicetree instead of hardcoding it, which allows us to reuse sun6i-pll6
    for our pll8.

    Patch 4 prepares the sunxi pinctrl driver for building the SoC specific parts
    as modules. This is later used for the H3 pinctrl driver. I believe the other
    sunxi SoCs could or should be changed to tristate too, but that's independend
    from this series and I wouldn't be able to test them anyway.

    The remaining patches add H3 support.

    Patch 5 adds machine support for the H3.

    Patch 6 adds support for the basic clocks.

    Patch 7 adds the pin sets for the H3 main PIO.

    Patch 8 adds a new compatible for the H3 reset controller

    Patch 9 adds the DTSI for the H3.

    Patch 10 adds a DTS for the Orange Pi Plus SBC, which these patches
    were developed and tested with.


    Changes since v1:
    - Update sunxi README in Documentation
    - Add the multiple parents gates and use them for bus-gates instead of
    ahb1, ahb2, apb1 and apb2 gates
    - Merge the pll8 clock with sun6i pll6
    - Merge the ahb12, apb1 and apb2 resets to bus-resets with own compatible
    - Add sun6i_timer_init to sun8i machine
    - Remove the single SoC names from machine definition, its sun8i family
    - Make the pinctrl driver tristate and put its Kconfig entry in the right order
    - Rename pinctrl "scr" to "sim" and clock "sim" to "scr" to match user manual
    - Remove the address paragraph from GPL in dts and dtsi
    - Some style cleanup and line wrapping in dtsi
    - Add ARM architected timers
    - dmaengine isn't included anymore, it is merged already

    Best Regards,
    Jens
