> ==================
> This series gathers patches to support the Allwinner H616 SoC. This
> is
> a rather uninspired SoC (Quad-A53 with the usual peripherals), but
> allows for some cheap development boards and TV boxes, and supports
> up to 4GB of DRAM.
>
> Various DT binding patches are sprinkled throughout the series, to
> add
> the new compatible names right before they are used.
> Patch 1/21 is the usual drive-by fix, discovered while staring at
> the H6 clock code.
> Patch 3 and 4 add pinctrl support, with the "-R" controller now being
> crippled down to two I2C pins only. If we grow tired of repeating
> this
> exercise for every new SoC variant, I am happy to revive my more
> versatile sunxi pinctrl driver effort from a few years back [1].
> Patch 6 and 7 add clock support. For the -R clock this is shared with
> the H6 code, as the clocks are identical, with the H616 just having
> fewer of them. The main clocks are different enough to warrant a
> separate
> file.
> Patch 08/21 is pulling a patch from Yangtao's A100 series, since we
> need
> the same fix for MMC support. This will probably be merged
> separately,
> I just include this here to provide a bootable solution.
> Patch 10 teaches the AXP MFD driver to get along without having an
> interrupt, as the H616 apparently does not have an NMI controller
> anymore.
> Patch 12 and 13 add some tweaks to the syscon and EMAC driver, to
> deal
> with the second EMAC clock used for the second Ethernet controller.
> Patches 14 and 15 *try* to add USB support. The same approach works
> with
> the very similar U-Boot PHY driver, but for some reason still fail in
> Linux. Maybe someone spots the issue and can help fixing it?
There's a judge currently checks for phy type A83T/H6. You may need to
add H616 there.
Or should we have a bool in the data struct to mark it? I think all
chips that need that is 28nm.
