Subject: [PATCH v4 0/3] Fix STi aliases property name

From: Patrice Chotard <[email protected]>

Since dtc v1.4.6-9-gaadd0b65c987, when compiling dtb with W=1 option,
the following warnings are triggered :

arch/arm/boot/dts/stih418-b2199.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/arm/boot/dts/stih407-b2120.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/arm/boot/dts/stih410-b2260.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'
arch/arm/boot/dts/stih410-b2120.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-'

_ Patch 1, convert the aliases property name in lowercase in
all STi board dts files.

_ Patch 2, remove "console=serialN" from bootargs property

_ Patch 3, rework the tty driver st-asc accordingly, as aliases id is retrieved
using of_alias_get_id() with a defined string with is not lowercase only.

v4: Fix Rob Herring's remarks :
_ reorder patches, first st-asc driver update and the DTS patches
in order to not break boot.
_ squash chunks of previous patch 1 into previous patch 2

v3: Fix Rob Herring's remarks :
_ remove "console=serialN,115200" from bootargs and use prefered stdout-path property
_ update st-asc driver with "serial" alias prefix and keep "ttyAS" in second choice

v2: Fix Rob Herring's remarks :
_ use serialN instead of ttyasN aliases to not break ABI
_ remove useless stdout-path property
_ update st-asc driver with "serial" alias prefix

Subject: [PATCH v4 1/3] tty: st-asc: Update tty alias

From: Patrice Chotard <[email protected]>

Since dtc v1.4.6-9-gaadd0b65c987, aliases property name
must include only lowercase and '-'.

After having updated all STi boards serial aliases from "ttyASN"
to "serialN", st-asc driver need to be updated accordingly as tty
aliases id is retrieved using of_alias_get_id().

Update serial aliases from "ttyASN" to more common "serialN".

Since dtc v1.4.6-9-gaadd0b65c987, aliases property name must
be lowercase only. This allows to fix following dtc warnings:

This patch does not apply at all, are you sure you made it correctly?

Can you please fix it up and resend?
