[PATCH v2 0/5] i2c: meson-axg: add I2C controller driver

[Yixun Lan]

This patch set try to add I2C controller driver for
the Amlogic's Meson-AXG SoC.

Changes since v1 [1]
 - update dt-bindings doc (Neil Armstrong)
 - make meson_i2c_data const (Martin Blumenstingl)
 - DTS: adjust naming, change from the 'i2c_m0' to 'i2c0' style

[PATCH v2 2/5] i2c: meson: add configurable divider factors

[Yixun Lan]

From: Jian Hu <jian.hu@amlogic.com>

This patch try to add support for I2C controller in Meson-AXG SoC,
Due to the IP changes between I2C controller, we need to introduce
a compatible data to make the divider factor configurable.

this is merely a ping, do you have any comment on this patch?
or could you take this patch along with patch 1 [1](with Rob's Ack) if
you think it's ready/good?

thanks

Applied to for-next, thanks!

But I got two build warnings, please fix them with an incremental patch:

drivers/i2c/busses/i2c-meson.c:103: warning: No description found for parameter 'data'
drivers/i2c/busses/i2c-meson.c:103: warning: Excess struct member 'irq' description in 'meson_i2c'

first, many thanks for pushing this..

I understand from above warnings, and can compose a patch to fix this.

but, I didn't get this build warnings while test locally, so is there
any specific compiler option that I need to pass to?

Could you have a look at these two patches?  They've been
acked/reviewed/tested and are just waiting your review/merge.

Once you've merged, I'll take the DT patches through my amlogic tree.

Thanks,

Kevin

Thanks!

The DT patches are now queued in the amlogic tree (branch: v4.17/dt64)
