Subject: [RFC 05/11] dt-bindings: soc: realtek: rtd1195-chip: Extend reg property
Date: Sun, 3 Nov 2019 02:36:39 +0100 [thread overview]
Message-ID: <20191103013645.9856-6-afaerber@suse.de> (raw)
In-Reply-To: <20191103013645.9856-1-afaerber@suse.de>
Allow to optionally specify a second register to identify the chip.
Whether needed and which register to specify depends on the family;
RTD1295 family will want the CHIP_INFO1 register.
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
A SoC specific binding would defeat the purpose of the generic Linux driver;
is it possible to check the root node's compatible in an if: expression
to prohibit using more than one reg on "realtek,rtd1195"?
