Sebastian, That's interesting! For the Cubox and the AMX33XX boards, the I2C address of the HDMI registers is 0x70, and the I2C address of the CEC registers is 0x34. For other boards using the TDA998x family, if the I2C address is different from 0x70, have you an idea about what can be the CEC I2C address? (this value is actually hard-coded in the TDA998x driver) -- Ken ar c'henta? | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jean-Francois Moine Subject: Re: [PATCH] ASoC: tda998x: Fix lack of required reg in DT documentation Date: Thu, 20 Mar 2014 14:01:56 +0100 Message-ID: <20140320140156.5d768b1f@armhf> References: <20140320092639.48F68A6279@smtp3-g21.free.fr> <532ADFD8.80301@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64 Return-path: In-Reply-To: <532ADFD8.80301@gmail.com> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" To: Sebastian Hesselbarth Cc: devicetree@vger.kernel.org, Russell King - ARM Linux , linux-arm-kernel@lists.infradead.org, dri-devel@lists.freedesktop.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org T24gVGh1LCAyMCBNYXIgMjAxNCAxMzozMjoyNCArMDEwMApTZWJhc3RpYW4gSGVzc2VsYmFydGgg PHNlYmFzdGlhbi5oZXNzZWxiYXJ0aEBnbWFpbC5jb20+IHdyb3RlOgoKPiA+ICsgIC0gcmVnOiBJ MkMgYWRkcmVzcyAtIG11c3QgYmUgPDB4NzA+ICAKPiAKPiBUREE5OTgzYiBkYXRhc2hlZXQgc2F5 czoKPiAKPiAiQml0cyBBMCBhbmQgQTEgb2YgdGhlIEkyQy1idXMgZGV2aWNlIGFkZHJlc3MgYXJl IGV4dGVybmFsbHkgc2VsZWN0ZWQKPiBieSBwaW5zIEEwIGFuZCBBMS4iCj4gCj4gVGhlcmVmb3Jl LCAweDcwLCAweDcxLCAweDcyLCBhbmQgMHg3MyBhcmUgdmFsaWQgaTJjIGFkZHJlc3Nlcy4KClNl YmFzdGlhbiwKClRoYXQncyBpbnRlcmVzdGluZyEKCkZvciB0aGUgQ3Vib3ggYW5kIHRoZSBBTVgz M1hYIGJvYXJkcywgdGhlIEkyQyBhZGRyZXNzIG9mIHRoZSBIRE1JCnJlZ2lzdGVycyBpcyAweDcw LCBhbmQgdGhlIEkyQyBhZGRyZXNzIG9mIHRoZSBDRUMgcmVnaXN0ZXJzIGlzIDB4MzQuCgpGb3Ig b3RoZXIgYm9hcmRzIHVzaW5nIHRoZSBUREE5OTh4IGZhbWlseSwgaWYgdGhlIEkyQyBhZGRyZXNz IGlzCmRpZmZlcmVudCBmcm9tIDB4NzAsIGhhdmUgeW91IGFuIGlkZWEgYWJvdXQgd2hhdCBjYW4g YmUgdGhlIENFQyBJMkMKYWRkcmVzcz8gKHRoaXMgdmFsdWUgaXMgYWN0dWFsbHkgaGFyZC1jb2Rl ZCBpbiB0aGUgVERBOTk4eCBkcml2ZXIpCgotLSAKS2VuIGFyIGMnaGVudGHDsQl8CSAgICAgICoq IEJyZWl6aCBoYSBMaW51eCBhdGF2ISAqKgpKZWYJCXwJCWh0dHA6Ly9tb2luZWpmLmZyZWUuZnIv Cl9fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fX19fCmRyaS1kZXZl bCBtYWlsaW5nIGxpc3QKZHJpLWRldmVsQGxpc3RzLmZyZWVkZXNrdG9wLm9yZwpodHRwOi8vbGlz dHMuZnJlZWRlc2t0b3Aub3JnL21haWxtYW4vbGlzdGluZm8vZHJpLWRldmVsCg== From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1757914AbaCTNBo (ORCPT ); Thu, 20 Mar 2014 09:01:44 -0400 Received: from smtp5-g21.free.fr ([212.27.42.5]:43279 "EHLO smtp5-g21.free.fr" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751226AbaCTNBm convert rfc822-to-8bit (ORCPT ); Thu, 20 Mar 2014 09:01:42 -0400 Date: Thu, 20 Mar 2014 14:01:56 +0100 From: Jean-Francois Moine To: Sebastian Hesselbarth Cc: Russell King - ARM Linux , devicetree@vger.kernel.org, dri-devel@lists.freedesktop.org, linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org Subject: Re: [PATCH] ASoC: tda998x: Fix lack of required reg in DT documentation Message-ID: <20140320140156.5d768b1f@armhf> In-Reply-To: <532ADFD8.80301@gmail.com> References: <20140320092639.48F68A6279@smtp3-g21.free.fr> <532ADFD8.80301@gmail.com> X-Mailer: Claws Mail 3.9.3 (GTK+ 2.24.22; arm-unknown-linux-gnueabihf) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8BIT Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org On Thu, 20 Mar 2014 13:32:24 +0100 Sebastian Hesselbarth wrote: > > + - reg: I2C address - must be <0x70> > > TDA9983b datasheet says: > > "Bits A0 and A1 of the I2C-bus device address are externally selected > by pins A0 and A1." > > Therefore, 0x70, 0x71, 0x72, and 0x73 are valid i2c addresses.
