From 4b77a23f37e6b62b784fcd4f335fe4a30f1c4b2d Mon Sep 17 00:00:00 2001 From: Robby Cai Date: Thu, 5 Sep 2013 17:55:15 +0800 Subject: [PATCH] ENGR00275034-3 camera: ov5640: port the driver from 3.5.7 from commit 9293d3aaef4886eae9a500f0dabdcd2b679422b4 and commit cb1d78fc935fa00be03ae1a7b66477ad518a09dc, branch imx_3.5.7 This patch also does - use module_i2c_driver() instead of module_init/exit. - set the regulator reference pointer to NULL if it's not found in DT. Otherwise call regulator_enable/disable() on it will cause dump since the codes only check the regulator against NULL before the call and it's not NULL but still invalid. - drop gpo regulator definition and operations since it's of no use Signed-off-by: Robby Cai --- drivers/media/platform/mxc/capture/Kconfig | 6 + drivers/media/platform/mxc/capture/Makefile | 1 + drivers/media/platform/mxc/capture/ov5640.c | 1945 +++++++++++++++++++ 3 files changed, 1952 insertions(+) create mode 100644 drivers/media/platform/mxc/capture/ov5640.c diff --git a/drivers/media/platform/mxc/capture/Kconfig b/drivers/media/platform/mxc/capture/Kconfig index 393bb7f70c34..762de46f7c62 100644 --- a/drivers/media/platform/mxc/capture/Kconfig +++ b/drivers/media/platform/mxc/capture/Kconfig @@ -3,3 +3,9 @@ config VIDEO_MXC_CSI_CAMERA depends on VIDEO_MXC_CAPTURE && VIDEO_V4L2 ---help--- This is the video4linux2 capture driver based on CSI module. + +config MXC_CAMERA_OV5640 + tristate "OmniVision ov5640 camera support" + depends on !VIDEO_MXC_EMMA_CAMERA && I2C + ---help--- + If you plan to use the ov5640 Camera with your MXC system, say Y here. diff --git a/drivers/media/platform/mxc/capture/Makefile b/drivers/media/platform/mxc/capture/Makefile index b1ca343d82f1..2fc2596038f9 100644 --- a/drivers/media/platform/mxc/capture/Makefile +++ b/drivers/media/platform/mxc/capture/Makefile @@ -1 +1,2 @@ obj-$(CONFIG_VIDEO_MXC_CSI_CAMERA) += fsl_csi.o csi_v4l2_capture.o +obj-$(CONFIG_MXC_CAMERA_OV5640) += ov5640.o diff --git a/drivers/media/platform/mxc/capture/ov5640.c b/drivers/media/platform/mxc/capture/ov5640.c new file mode 100644 index 000000000000..cfb86ed3b565 --- /dev/null +++ b/drivers/media/platform/mxc/capture/ov5640.c @@ -0,0 +1,1945 @@ +/* + * Copyright (C) 2012-2013 Freescale Semiconductor, Inc.
