(this value is actually hard-coded in the TDA998x driver) I had a look again on the tda998x driver from NXP and the linux tda998x driver: - the NXP driver handles the TDAs 19989, 19988, 9984, 9983 and 9981. It accesses the tda registers only at I2C address 0x70 and 0x34 (hard-coded values in the driver). - the linux tda998x driver handles only the TDAs 19988 and 19989. As we have no documentation about the chips TDA 19988 and 19989, may the HDMI I2C addresses of these chips be different from 0x70? -- 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 14:25:08 +0100 Message-ID: <20140320142508.557fb860@armhf> References: <20140320092639.48F68A6279@smtp3-g21.free.fr> <532ADFD8.80301@gmail.com> <20140320140156.5d768b1f@armhf> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: base64 Return-path: In-Reply-To: <20140320140156.5d768b1f@armhf> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" To: Jean-Francois Moine Cc: devicetree@vger.kernel.org, Russell King - ARM Linux , linux-kernel@vger.kernel.org, dri-devel@lists.freedesktop.org, linux-arm-kernel@lists.infradead.org, Sebastian Hesselbarth List-Id: devicetree@vger.kernel.org T24gVGh1LCAyMCBNYXIgMjAxNCAxNDowMTo1NiArMDEwMApKZWFuLUZyYW5jb2lzIE1vaW5lIDxt b2luZWpmQGZyZWUuZnI+IHdyb3RlOgoKPiBGb3Igb3RoZXIgYm9hcmRzIHVzaW5nIHRoZSBUREE5 OTh4IGZhbWlseSwgaWYgdGhlIEkyQyBhZGRyZXNzIGlzCj4gZGlmZmVyZW50IGZyb20gMHg3MCwg aGF2ZSB5b3UgYW4gaWRlYSBhYm91dCB3aGF0IGNhbiBiZSB0aGUgQ0VDIEkyQwo+IGFkZHJlc3M/ ICh0aGlzIHZhbHVlIGlzIGFjdHVhbGx5IGhhcmQtY29kZWQgaW4gdGhlIFREQTk5OHggZHJpdmVy KQoKSSBoYWQgYSBsb29rIGFnYWluIG9uIHRoZSB0ZGE5OTh4IGRyaXZlciBmcm9tIE5YUCBhbmQg dGhlIGxpbnV4IHRkYTk5OHgKZHJpdmVyOgoKLSB0aGUgTlhQIGRyaXZlciBoYW5kbGVzIHRoZSBU REFzIDE5OTg5LCAxOTk4OCwgOTk4NCwgOTk4MyBhbmQgOTk4MS4KICBJdCBhY2Nlc3NlcyB0aGUg dGRhIHJlZ2lzdGVycyBvbmx5IGF0IEkyQyBhZGRyZXNzIDB4NzAgYW5kIDB4MzQKICAoaGFyZC1j b2RlZCB2YWx1ZXMgaW4gdGhlIGRyaXZlcikuCgotIHRoZSBsaW51eCB0ZGE5OTh4IGRyaXZlciBo YW5kbGVzIG9ubHkgdGhlIFREQXMgMTk5ODggYW5kIDE5OTg5LgoKQXMgd2UgaGF2ZSBubyBkb2N1 bWVudGF0aW9uIGFib3V0IHRoZSBjaGlwcyBUREEgMTk5ODggYW5kIDE5OTg5LAptYXkgdGhlIEhE TUkgSTJDIGFkZHJlc3NlcyBvZiB0aGVzZSBjaGlwcyBiZSBkaWZmZXJlbnQgZnJvbSAweDcwPwoK LS0gCktlbiBhciBjJ2hlbnRhw7EJfAkgICAgICAqKiBCcmVpemggaGEgTGludXggYXRhdiEgKioK SmVmCQl8CQlodHRwOi8vbW9pbmVqZi5mcmVlLmZyLwpfX19fX19fX19fX19fX19fX19fX19fX19f X19fX19fX19fX19fX19fX19fX19fXwpkcmktZGV2ZWwgbWFpbGluZyBsaXN0CmRyaS1kZXZlbEBs aXN0cy5mcmVlZGVza3RvcC5vcmcKaHR0cDovL2xpc3RzLmZyZWVkZXNrdG9wLm9yZy9tYWlsbWFu L2xpc3RpbmZvL2RyaS1kZXZlbAo= From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: (majordomo@vger.kernel.org) by vger.kernel.org via listexpand id S1758654AbaCTNY5 (ORCPT ); Thu, 20 Mar 2014 09:24:57 -0400 Received: from smtp5-g21.free.fr ([212.27.42.5]:35366 "EHLO smtp5-g21.free.fr" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1757872AbaCTNYz convert rfc822-to-8bit (ORCPT ); Thu, 20 Mar 2014 09:24:55 -0400 X-Greylist: delayed 1392 seconds by postgrey-1.27 at vger.kernel.org; Thu, 20 Mar 2014 09:24:54 EDT Date: Thu, 20 Mar 2014 14:25:08 +0100 From: Jean-Francois Moine To: Jean-Francois Moine Cc: Sebastian Hesselbarth , devicetree@vger.kernel.org, Russell King - ARM Linux , linux-arm-kernel@lists.infradead.org, dri-devel@lists.freedesktop.org, linux-kernel@vger.kernel.org Subject: Re: [PATCH] ASoC: tda998x: Fix lack of required reg in DT documentation Message-ID: <20140320142508.557fb860@armhf> In-Reply-To: <20140320140156.5d768b1f@armhf> References: <20140320092639.48F68A6279@smtp3-g21.free.fr> <532ADFD8.80301@gmail.com> <20140320140156.5d768b1f@armhf> 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 14:01:56 +0100 Jean-Francois Moine wrote: > 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?
