Subject: [PATCH v2] arm64: dts: ti: k3-j721e: Rename mux header and update macro names
Date: Fri, 18 Sep 2020 19:59:30 +0300	[thread overview]
Message-ID: <20200918165930.2031-1-rogerq@ti.com> (raw)

We intend to use one header file for SERDES MUX for all
TI SoCs so rename the header file.

The exsting macros are too generic. Prefix them with SoC name.

While at that, add the missing configurations for completeness.

Reported-by: Peter Rosin <peda@axentia.se>
Fixes: b766e3b0d5f6 ("arm64: dts: ti: k3-j721e-main: Add system controller node and SERDES lane mux")
Signed-off-by: Roger Quadros <rogerq@ti.com>
Acked-by: Peter Rosin <peda@axentia.se>
---

Changelog:
v2
- use _DT_BINDINGS_MUX_TI_SERDES
- Add unused lane configurations for completeness
