From mboxrd@z Thu Jan 1 00:00:00 1970 From: Benjamin Gaignard Subject: [PATCH v2 0/2] cec: STM32 driver Date: Tue, 16 May 2017 14:56:21 +0200 Message-ID: <1494939383-18937-1-git-send-email-benjamin.gaignard@linaro.org> Return-path: Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: yannick.fertre-qxv4g6HH51o@public.gmane.org, alexandre.torgue-qxv4g6HH51o@public.gmane.org, hverkuil-qWit8jRvyhVmR6Xm/wNWPw@public.gmane.org, devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-media-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org, hans.verkuil-FYB4Gu1CFyUAvxtiuMwx3w@public.gmane.org Cc: Benjamin Gaignard List-Id: devicetree@vger.kernel.org version 2: - fix typo in compagnie name - add yannick sign-off - use cec_message instead of custom struct in cec device - add monitor mode I don't change the split between irq handler and irq thread because it would had mean to handle all errors cases irq handler to keep a correct sequence. I don't think it is critical as it is since cec is a very slow protocol. This serie of patches add cec driver for STM32 platforms. This code doesn't implement cec notifier because STM32 doesn't provide HDMI yet but it will be added later. Those patches have been developped on top of media_tree master branch where STM32 DCMI code has not been merged so conflict in Kconfig and Makefile could occur depending of merge ordering. Compliance has been tested on STM32F769. ~ # cec-ctl -p 1.0.0.0 --playback Driver Info: Driver Name : stm32-cec Adapter Name : stm32-cec Capabilities : 0x0000000f Physical Address Logical Addresses Transmit Passthrough Driver version : 4.11.0 Available Logical Addresses: 1 Physical Address : 1.0.0.0 Logical Address Mask : 0x0010 CEC Version : 2.0 Vendor ID : 0x000c03 (HDMI) OSD Name : 'Playback' Logical Addresses : 1 (Allow RC Passthrough) Logical Address : 4 (Playback Device 1) Primary Device Type : Playback Logical Address Type : Playback All Device Types : Playback RC TV Profile : None Device Features : None ~ # cec-compliance -A cec-compliance SHA : 6acac5cec698de39b9398b66c4f5f4db6b2730d8 Driver Info: Driver Name : stm32-cec Adapter Name : stm32-cec Capabilities : 0x0000000f Physical Address Logical Addresses Transmit Passthrough Driver version : 4.11.0 Available Logical Addresses: 1 Physical Address : 1.0.0.0 Logical Address Mask : 0x0010 CEC Version : 2.0 Vendor ID : 0x000c03 Logical Addresses : 1 (Allow RC Passthrough) Logical Address : 4 Primary Device Type : Playback Logical Address Type : Playback All Device Types : Playback RC TV Profile : None Device Features : None Compliance test for device /dev/cec0: The test results mean the following: OK Supported correctly by the device.
