[PATCH v5 0/8] arm: Add basic support for MediaTek MT8127 & MT8135 SoCs

[Yingjoe Chen]

This is v5 of adding basic device tree support for MT8127 & MT8135.
This series is based on v3.18-rc1

This version fix board model name and change to use 32bits address for
mt8127/mt8135 dtsi. I also took the chance to do a minor wording change
in dt-bindings. Please note we already have some patches (uart, reset,
i2c, pinctrl, intpol) thats depends on old version, and should be changed
if this version is merged.

We are planning to upstream drivers for MT8127 & MT8135 SoCs.
MT8135 is a tablet soc featuring 2 CA7 + 2 CA15. MT8127 is a
tablet soc with 4 CA7. They share many similar IP components
with MT65xx series.

Changes in v5:
 - Using 32bits address instead of 64bits in dtsi.
 - Fix model name error
 - Adjust wording in dtbindings.

Changes in v4:
 - Include config options for different mediatek SoCs.

Changes in v3:
 - Changing earlyprintk order and dt-binding based on Matthias' suggestion.

v2:
 - Change timer compatible string.
 - Build dtb for mt8127 & mt8135
 - Adding earlyprintk support for mt8127 & mt8135

Re: [PATCH v5' 1/8] ARM: mediatek: Add basic support for mt8127

[Yingjoe Chen]

Hi, Matthias, Arnd,

After previous discussion[1], I'm not sure which one do you preferred
for mt8127/mt8135, so I send 64bits address version again. Trying to not
SPAM too much, I only send the difference(first 4 patches) this time.

We do have SoC that need >4GB address, so at least those will need to
use 64bits address. If we want to have a consistent look, 64bits is the
way to go. Also we already have some patches under review now using
64bits address. So I preferred this one, but both versions are OK to me.

Please help to review this and let me know anything you want me to
change. Thanks.

Joe.C

Regarding Arnd's last email, the 64 bit is the right way.

Hi Matthias,

Ok, please use this v5' then.
