Subject: [PATCH v2 5/5] dt-bindings: Update the isa string description
Date: Tue, 30 Jul 2019 18:24:18 -0700 [thread overview]
Message-ID: <20190731012418.24565-6-atish.patra@wdc.com> (raw)
In-Reply-To: <20190731012418.24565-1-atish.patra@wdc.com>
The yaml documentation description of isa strings section doesn't
specify anything about the case sensitiveness of the isa strings.
The RISC-V specification clearly specifies it to be case insensitive.
However, Linux kernel supports only lower case isa strings.
Update the yaml documentation accordingly to avoid any confusion.
