Hi all,

Here are four patches to make dra7 l4 devices to probe with ti-sysc
driver similar to what we've already done for omap4. The related
legacy hwmod platform data will be removed few merge cycles later.

I've only lightly tested these so far, but then again with this being
SoC #4 to get converted things should be quite trivial now.

These are based on v4.19-rc5 merged with my omap-for-v4.20/dt branch
plus the following additional series of patches:

[PATCH 00/11] clk: ti: clkctrl data split based on clkdm boundaries
[PATCH 0/3] ARM: dts: am3/am4/dra7 clkctrl data conversion
[PATCH 0/4] TI sysc driver updates for am335x and am437x
[PATCH 0/4] Update am437x and am335x dts to probe with ti-sysc
[PATCH] i2c: omap: Use noirq system sleep pm ops to idle device for suspend

At least v4.19-rc3 is needed for commit 18eb8aea7fb2 ("net: ethernet:
cpsw-phy-sel: prefer phandle for phy sel") and omap-for-v4.20/dt
is needed to avoid conflicts with clean-up.

I've also pushed out a new temporary branch for people to test as
as omap-for-v4.20/dt-ti-sysc-tmp-testing-v2 [0][1].

Regards,

Tony

Hey Tony,

I tried [1]. I see gpio throwing some errors while suspending:
