CCDC has several modules + * such as Defect Pixel Correction, Color Space Conversion etc to + * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This + * module also allows application to configure individual + * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL. + * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header + * files. The setparams() API is called by vpfe_capture driver + * to configure module parameters. This file is named DM644x so that other + * variants such DM6443 may be supported using the same module. + * + * TODO: Test Raw bayer parameter settings and bayer capture + * Split module parameter structure to module specific ioctl structs + * investigate if enum used for user space type definition + * to be replaced by #defines or integer + */ +#include <linux/platform_device.h> +#include <linux/uaccess.h> +#include <linux/videodev2.h> +#include <media/davinci/dm644x_ccdc.h> +#include <media/davinci/vpss.h> +#include "dm644x_ccdc_regs.h" +#include "ccdc_hw_device.h" + +MODULE_LICENSE("GPL"); +MODULE_DESCRIPTION("CCDC Driver for DM6446"); +MODULE_AUTHOR("Texas Instruments"); + +static struct device *dev; + +/* Object for CCDC raw mode */ +static struct ccdc_params_raw ccdc_hw_params_raw = { + .pix_fmt = CCDC_PIXFMT_RAW, + .frm_fmt = CCDC_FRMFMT_PROGRESSIVE, + .win = CCDC_WIN_VGA, + .fid_pol = VPFE_PINPOL_POSITIVE, + .vd_pol = VPFE_PINPOL_POSITIVE, + .hd_pol = VPFE_PINPOL_POSITIVE, + .config_params = { + .data_sz = CCDC_DATA_10BITS, + }, +}; + +/* Object for CCDC ycbcr mode */ +static struct ccdc_params_ycbcr ccdc_hw_params_ycbcr = { + .pix_fmt = CCDC_PIXFMT_YCBCR_8BIT, + .frm_fmt = CCDC_FRMFMT_INTERLACED, + .win = CCDC_WIN_PAL, + .fid_pol = VPFE_PINPOL_POSITIVE, + .vd_pol = VPFE_PINPOL_POSITIVE, + .hd_pol = VPFE_PINPOL_POSITIVE, + .bt656_enable = 1, + .pix_order = CCDC_PIXORDER_CBYCRY, + .buf_type = CCDC_BUFTYPE_FLD_INTERLEAVED +}; + +#define CCDC_MAX_RAW_YUV_FORMATS 2 + +/* Raw Bayer formats */ +static u32 ccdc_raw_bayer_pix_formats[] = + {V4L2_PIX_FMT_SBGGR8, V4L2_PIX_FMT_SBGGR16}; + +/* Raw YUV formats */ +static u32 ccdc_raw_yuv_pix_formats[] = + {V4L2_PIX_FMT_UYVY, V4L2_PIX_FMT_YUYV}; + +static void *__iomem ccdc_base_addr; +static int ccdc_addr_size; +static enum vpfe_hw_if_type ccdc_if_type; + +/* register access routines */ +static inline u32 regr(u32 offset) +{ + return __raw_readl(ccdc_base_addr + offset); +} + +static inline void regw(u32 val, u32 offset) +{ + __raw_writel(val, ccdc_base_addr + offset); +} + +static void ccdc_set_ccdc_base(void *addr, int size) +{ + ccdc_base_addr = addr; + ccdc_addr_size = size; +} + +static void ccdc_enable(int flag) +{ + regw(flag, CCDC_PCR); +} + +static void ccdc_enable_vport(int flag) +{ + if (flag) + /* enable video port */ + regw(CCDC_ENABLE_VIDEO_PORT, CCDC_FMTCFG); + else + regw(CCDC_DISABLE_VIDEO_PORT, CCDC_FMTCFG); +} + +/* + * ccdc_setwin() + * This function will configure the window size + * to be capture in CCDC reg + */ +void ccdc_setwin(struct v4l2_rect *image_win, + enum ccdc_frmfmt frm_fmt, + int ppc) +{ + int horz_start, horz_nr_pixels; + int vert_start, vert_nr_lines; + int val = 0, mid_img = 0; + + dev_dbg(dev, "\nStarting ccdc_setwin..."); + /* + * ppc - per pixel count. indicates how many pixels per cell + * output to SDRAM. example, for ycbcr, it is one y and one c, so 2. + * raw capture this is 1 + */ + horz_start = image_win->left << (ppc - 1); + horz_nr_pixels = (image_win->width << (ppc - 1)) - 1; + regw((horz_start << CCDC_HORZ_INFO_SPH_SHIFT) | horz_nr_pixels, + CCDC_HORZ_INFO); + + vert_start = image_win->top; + + if (frm_fmt == CCDC_FRMFMT_INTERLACED) { + vert_nr_lines = (image_win->height >> 1) - 1; + vert_start >>= 1; + /* Since first line doesn't have any data */ + vert_start += 1; + /* configure VDINT0 */ + val = (vert_start << CCDC_VDINT_VDINT0_SHIFT); + regw(val, CCDC_VDINT); + + } else { + /* Since first line doesn't have any data */ + vert_start += 1; + vert_nr_lines = image_win->height - 1; + /* + * configure VDINT0 and VDINT1.
