Message-ID: <5329727E.40604@atmel.com> Date: Wed, 19 Mar 2014 11:33:34 +0100 From: Nicolas Ferre <nicolas.ferre@...el.com> To: Alexandre Belloni <alexandre.belloni@...e-electrons.com> CC: Jean-Christophe Plagniol-Villard <plagnioj@...osoft.com>, <linux-arm-kernel@...ts.infradead.org>, <linux-kernel@...r.kernel.org> Subject: Re: [PATCH] Documentation: dt: list all compatible strings for at91 On 19/03/2014 11:26, Alexandre Belloni : > Avoids getting the newly introduced warning: > WARNING: DT compatible string "atmel,at91sam9g45-adc" appears un-documented -- check ./Documentation/devicetree/bindings/ > + compatible = "atmel,at91sam9g45-adc"; > > Introduced by: > bff5da433525 checkpatch: add DT compatible string documentation checks > > Signed-off-by: Alexandre Belloni <alexandre.belloni@...e-electrons.com> Ok, if it is needed. Acked-by: Nicolas Ferre <nicolas.ferre@...el.com> BTW, I do not see the devicetree maintainers in the list of CC. If it is done for other architectures, I am fine with it, but if we are the only one to start this move, I would like them to be aware.
