That means every last data of last line should be filled with 0, and not filled with the data of next line. - Update new ISP parameters immediately For those sub modules that have shadow registers in core isp, the new programing parameters would not be active if both CIF_ISP_CTRL_ISP_CFG_UPD_PERMANENT and CFG_UPD are not set. Now we configure CFG_UPD to force update the shadow registers when new ISP parameters are configured. - fix some ISP parameters config error Some ISP parameter config functions may override the old enable bit value, because the enable bits of these modules are in the same registers with parameters. So we should save the old enable bits firstly. - code styling and checkpatch fixes .../media/platform/rockchip/isp1/isp_params.c | 1604 +++++++++++++++++ .../media/platform/rockchip/isp1/isp_params.h | 50 + 2 files changed, 1654 insertions(+) create mode 100644 drivers/media/platform/rockchip/isp1/isp_params.c create mode 100644 drivers/media/platform/rockchip/isp1/isp_params.h diff --git a/drivers/media/platform/rockchip/isp1/isp_params.c b/drivers/media/platform/rockchip/isp1/isp_params.c new file mode 100644 index 000000000000..7b470b6bf90f --- /dev/null +++ b/drivers/media/platform/rockchip/isp1/isp_params.c @@ -0,0 +1,1604 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Rockchip isp1 driver + * + * Copyright (C) 2017 Rockchip Electronics Co., Ltd. + */ + +#include +#include +#include +#include +#include /* for ISP params */ + +#include "dev.h" +#include "regs.h" + +#define RKISP1_ISP_PARAMS_REQ_BUFS_MIN 2 +#define RKISP1_ISP_PARAMS_REQ_BUFS_MAX 8 + +#define BLS_START_H_MAX_IS_VALID(val) ((val) < CIFISP_BLS_START_H_MAX) +#define BLS_STOP_H_MAX_IS_VALID(val) ((val) < CIFISP_BLS_STOP_H_MAX) + +#define BLS_START_V_MAX_IS_VALID(val) ((val) < CIFISP_BLS_START_V_MAX) +#define BLS_STOP_V_MAX_IS_VALID(val) ((val) < CIFISP_BLS_STOP_V_MAX) + +#define BLS_SAMPLE_MAX_IS_VALID(val) ((val) < CIFISP_BLS_SAMPLES_MAX) + +#define BLS_FIX_SUB_IS_VALID(val) \ + ((val) > (s16) CIFISP_BLS_FIX_SUB_MIN && (val) < CIFISP_BLS_FIX_SUB_MAX) + +#define RKISP1_ISP_DPCC_LINE_THRESH(n) (CIF_ISP_DPCC_LINE_THRESH_1 + 0x14 * (n)) +#define RKISP1_ISP_DPCC_LINE_MAD_FAC(n) (CIF_ISP_DPCC_LINE_MAD_FAC_1 + 0x14 * (n)) +#define RKISP1_ISP_DPCC_PG_FAC(n) (CIF_ISP_DPCC_PG_FAC_1 + 0x14 * (n)) +#define RKISP1_ISP_DPCC_RND_THRESH(n) (CIF_ISP_DPCC_RND_THRESH_1 + 0x14 * (n)) +#define RKISP1_ISP_DPCC_RG_FAC(n) (CIF_ISP_DPCC_RG_FAC_1 + 0x14 * (n)) +#define RKISP1_ISP_CC_COEFF(n) (CIF_ISP_CC_COEFF_0 + (n) * 4) + +static inline void rkisp1_iowrite32(struct rkisp1_isp_params_vdev *params_vdev, + u32 value, u32 addr) +{ + iowrite32(value, params_vdev->dev->base_addr + addr);

The new V4L2 async notifier API requires notifiers to be initialized by a call to v4l2_async_notifier_init() before being used, do so. - Add missing module device table - use clk_bulk framework - add missing notifiers cleanups - s/strlcpy/strscpy - normalize bus_info name - fix s_stream error path, stream_cnt wans't being decremented properly - use devm_platform_ioremap_resource() helper - s/deice/device - redesign: remove mipi/csi subdevice, sensors connect directly to the isp subdevice in the media topology now. - remove "saved_state" member from rkisp1_stream struct - Reverse the order of MIs - Simplify MI interrupt handling Rather than adding unnecessary indirection, just use stream index to handle MI interrupt enable/disable/clear, since the stream index matches the order of bits now, thanks to previous patch. While at it, remove some dead code. - code styling and checkpatch fixes drivers/media/platform/Kconfig | 12 + drivers/media/platform/Makefile | 1 + drivers/media/platform/rockchip/isp1/Makefile | 7 + drivers/media/platform/rockchip/isp1/common.h | 101 +++ drivers/media/platform/rockchip/isp1/dev.c | 675 ++++++++++++++++++ drivers/media/platform/rockchip/isp1/dev.h | 97 +++ 6 files changed, 893 insertions(+) create mode 100644 drivers/media/platform/rockchip/isp1/Makefile create mode 100644 drivers/media/platform/rockchip/isp1/common.h create mode 100644 drivers/media/platform/rockchip/isp1/dev.c create mode 100644 drivers/media/platform/rockchip/isp1/dev.h diff --git a/drivers/media/platform/Kconfig b/drivers/media/platform/Kconfig index 8a19654b393a..346ad2a2ee3a 100644 --- a/drivers/media/platform/Kconfig +++ b/drivers/media/platform/Kconfig @@ -106,6 +106,18 @@ config VIDEO_QCOM_CAMSS select VIDEOBUF2_DMA_SG select V4L2_FWNODE +config VIDEO_ROCKCHIP_ISP1 + tristate "Rockchip Image Signal Processing v1 Unit driver" + depends on VIDEO_V4L2 && VIDEO_V4L2_SUBDEV_API + depends on ARCH_ROCKCHIP || COMPILE_TEST + select VIDEOBUF2_DMA_CONTIG + select VIDEOBUF2_VMALLOC + select V4L2_FWNODE + select PHY_ROCKCHIP_DPHY + default n + ---help--- + Support for ISP1 on the rockchip SoC. + config VIDEO_S3C_CAMIF tristate "Samsung S3C24XX/S3C64XX SoC Camera Interface driver" depends on VIDEO_V4L2 && I2C && VIDEO_V4L2_SUBDEV_API diff --git a/drivers/media/platform/Makefile b/drivers/media/platform/Makefile index 7cbbd925124c..f9fcf8e7c513 100644 --- a/drivers/media/platform/Makefile +++ b/drivers/media/platform/Makefile @@ -69,6 +69,7 @@ obj-$(CONFIG_VIDEO_RENESAS_FDP1) += rcar_fdp1.o obj-$(CONFIG_VIDEO_RENESAS_JPU) += rcar_jpu.o obj-$(CONFIG_VIDEO_RENESAS_VSP1) += vsp1/ +obj-$(CONFIG_VIDEO_ROCKCHIP_ISP1) += rockchip/isp1/ obj-$(CONFIG_VIDEO_ROCKCHIP_RGA) += rockchip/rga/ obj-y += omap/ diff --git a/drivers/media/platform/rockchip/isp1/Makefile b/drivers/media/platform/rockchip/isp1/Makefile new file mode 100644 index 000000000000..72706e80fc8b --- /dev/null +++ b/drivers/media/platform/rockchip/isp1/Makefile @@ -0,0 +1,7 @@ +obj-$(CONFIG_VIDEO_ROCKCHIP_ISP1) += rockchip-isp1.o +rockchip-isp1-objs += rkisp1.o \ + dev.o \ + regs.o \ + isp_stats.o \ + isp_params.o \ + capture.o diff --git a/drivers/media/platform/rockchip/isp1/common.h b/drivers/media/platform/rockchip/isp1/common.h new file mode 100644 index 000000000000..606ce2793546 --- /dev/null +++ b/drivers/media/platform/rockchip/isp1/common.h @@ -0,0 +1,101 @@ +/* SPDX-License-Identifier: (GPL-2.0+ OR MIT) */ +/* + * Rockchip isp1 driver + * + * Copyright (C) 2017 Rockchip Electronics Co., Ltd. + */ + +#ifndef _RKISP1_COMMON_H +#define _RKISP1_COMMON_H + +#include +#include +#include +#include +#include +#include + +#define RKISP1_DEFAULT_WIDTH 800 +#define RKISP1_DEFAULT_HEIGHT 600 + +#define RKISP1_MAX_STREAM 2 +#define RKISP1_STREAM_MP 0 +#define RKISP1_STREAM_SP 1 + +#define RKISP1_PLANE_Y 0 +#define RKISP1_PLANE_CB 1 +#define RKISP1_PLANE_CR 2 + +enum rkisp1_sd_type { + RKISP1_SD_SENSOR, + RKISP1_SD_PHY_CSI, + RKISP1_SD_VCM, + RKISP1_SD_FLASH, + RKISP1_SD_MAX, +};
