It used to extract specific data from the ISC pipeline. For example if we want to output greyscale 8 bit, we would use limiting to 8 bits, and packaging to Luma component only. Create a product specific callback for initializing the RLP submodule of the pipeline [hverkuil: made isc_sama5d2_config_rlp static] Signed-off-by: Eugen Hristev Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- diff --git a/drivers/media/platform/atmel/atmel-isc-base.c b/drivers/media/platform/atmel/atmel-isc-base.c index aef0d65..67c16ca 100644 --- a/drivers/media/platform/atmel/atmel-isc-base.c +++ b/drivers/media/platform/atmel/atmel-isc-base.c @@ -719,11 +719,10 @@ static void isc_set_histogram(struct isc_device *isc, bool enable) static int isc_configure(struct isc_device *isc) { struct regmap *regmap = isc->regmap; - u32 pfe_cfg0, rlp_mode, dcfg, mask, pipeline; + u32 pfe_cfg0, dcfg, mask, pipeline; struct isc_subdev_entity *subdev = isc->current_subdev; pfe_cfg0 = isc->config.sd_format->pfe_cfg0_bps; - rlp_mode = isc->config.rlp_cfg_mode; pipeline = isc->config.bits_pipeline; dcfg = isc->config.dcfg_imode | isc->dcfg; @@ -736,8 +735,7 @@ static int isc_configure(struct isc_device *isc) regmap_update_bits(regmap, ISC_PFE_CFG0, mask, pfe_cfg0); - regmap_update_bits(regmap, ISC_RLP_CFG + isc->offsets.rlp, - ISC_RLP_CFG_MODE_MASK, rlp_mode); + isc->config_rlp(isc); regmap_write(regmap, ISC_DCFG + isc->offsets.dma, dcfg); diff --git a/drivers/media/platform/atmel/atmel-isc.h b/drivers/media/platform/atmel/atmel-isc.h index 1e6988f..abeef7b 100644 --- a/drivers/media/platform/atmel/atmel-isc.h +++ b/drivers/media/platform/atmel/atmel-isc.h @@ -231,6 +231,8 @@ struct isc_reg_offsets { * specific CC module * @config_gam: pointer to a function that initializes product * specific GAMMA module + * @config_rlp: pointer to a function that initializes product + * specific RLP module * @config_ctrls: pointer to a functoin that initializes product * specific v4l2 controls. * @@ -309,6 +311,7 @@ struct isc_device { void (*config_cbc)(struct isc_device *isc); void (*config_cc)(struct isc_device *isc); void (*config_gam)(struct isc_device *isc); + void (*config_rlp)(struct isc_device *isc); void (*config_ctrls)(struct isc_device *isc, const struct v4l2_ctrl_ops *ops); diff --git a/drivers/media/platform/atmel/atmel-sama5d2-isc.c b/drivers/media/platform/atmel/atmel-sama5d2-isc.c index 6973c65..292532d 100644 --- a/drivers/media/platform/atmel/atmel-sama5d2-isc.c +++ b/drivers/media/platform/atmel/atmel-sama5d2-isc.c @@ -117,6 +117,15 @@ static void isc_sama5d2_config_gam(struct isc_device *isc) /* No specific gamma configuration */ } +static void isc_sama5d2_config_rlp(struct isc_device *isc) +{ + struct regmap *regmap = isc->regmap; + u32 rlp_mode = isc->config.rlp_cfg_mode; + + regmap_update_bits(regmap, ISC_RLP_CFG + isc->offsets.rlp, + ISC_RLP_CFG_MODE_MASK, rlp_mode); +} + /* Gamma table with gamma 1/2.2 */ static const u32 isc_sama5d2_gamma_table[][GAMMA_ENTRIES] = { /* 0 --> gamma 1/1.8 */ @@ -267,6 +276,7 @@ static int atmel_isc_probe(struct platform_device *pdev) isc->config_cbc = isc_sama5d2_config_cbc; isc->config_cc = isc_sama5d2_config_cc; isc->config_gam = isc_sama5d2_config_gam; + isc->config_rlp = isc_sama5d2_config_rlp; isc->config_ctrls = isc_sama5d2_config_ctrls; isc->offsets.csc = ISC_SAMA5D2_CSC_OFFSET;
