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. +Add rlp to the reg offsets struct. +This will allow different products to have a different reg offset for this +particular module. + +Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> +Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> +Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> +--- + drivers/media/platform/atmel/atmel-isc-base.c | 4 ++-- + drivers/media/platform/atmel/atmel-isc-regs.h | 2 ++ + drivers/media/platform/atmel/atmel-isc.h | 2 ++ + drivers/media/platform/atmel/atmel-sama5d2-isc.c | 1 + + 4 files changed, 7 insertions(+), 2 deletions(-) + +--- a/drivers/media/platform/atmel/atmel-isc-base.c ++++ b/drivers/media/platform/atmel/atmel-isc-base.c +@@ -726,8 +726,8 @@ static int isc_configure(struct isc_devi + + regmap_update_bits(regmap, ISC_PFE_CFG0, mask, pfe_cfg0); + +- regmap_update_bits(regmap, ISC_RLP_CFG, ISC_RLP_CFG_MODE_MASK, +- rlp_mode); ++ regmap_update_bits(regmap, ISC_RLP_CFG + isc->offsets.rlp, ++ ISC_RLP_CFG_MODE_MASK, rlp_mode); + + regmap_write(regmap, ISC_DCFG, dcfg); + +--- a/drivers/media/platform/atmel/atmel-isc-regs.h ++++ b/drivers/media/platform/atmel/atmel-isc-regs.h +@@ -204,6 +204,8 @@ + /* Subsampling 4:2:2 to 4:2:0 Control Register */ + #define ISC_SUB420_CTRL 0x000003cc + ++/* Offset for RLP register specific to sama5d2 product */ ++#define ISC_SAMA5D2_RLP_OFFSET 0 + /* Rounding, Limiting and Packing Configuration Register */ + #define ISC_RLP_CFG 0x000003d0 + +--- a/drivers/media/platform/atmel/atmel-isc.h ++++ b/drivers/media/platform/atmel/atmel-isc.h +@@ -149,12 +149,14 @@ struct isc_ctrls { + * @cbc: Offset for the CBC register + * @sub422: Offset for the SUB422 register + * @sub420: Offset for the SUB420 register ++ * @rlp: Offset for the RLP register + */ + struct isc_reg_offsets { + u32 csc; + u32 cbc; + u32 sub422; + u32 sub420; ++ u32 rlp; + }; + + /* +--- a/drivers/media/platform/atmel/atmel-sama5d2-isc.c ++++ b/drivers/media/platform/atmel/atmel-sama5d2-isc.c +@@ -255,6 +255,7 @@ static int atmel_isc_probe(struct platfo + isc->offsets.cbc = ISC_SAMA5D2_CBC_OFFSET; + isc->offsets.sub422 = ISC_SAMA5D2_SUB422_OFFSET; + isc->offsets.sub420 = ISC_SAMA5D2_SUB420_OFFSET; ++ isc->offsets.rlp = ISC_SAMA5D2_RLP_OFFSET; + + /* sama5d2-isc - 8 bits per beat */ + isc->dcfg = ISC_DCFG_YMBSIZE_BEATS8 | ISC_DCFG_CMBSIZE_BEATS8; |
