MFCv10.10 is used in Exynos7880. There are other variants of MFCv10 used in Exynos8890 and Exynos7870. I have no plans to upstream the platform support for this SoC, may be other members of Samsung may take it up. But I will mention the SoCs in the next version. > > > > > - reg : Physical base address of the IP registers and length of memory > > mapped region. > > diff --git a/drivers/media/platform/s5p-mfc/regs-mfc-v10.h > > b/drivers/media/platform/s5p-mfc/regs-mfc-v10.h > > new file mode 100644 > > index 0000000..bd671a5 > > --- /dev/null > > +++ b/drivers/media/platform/s5p-mfc/regs-mfc-v10.h > > @@ -0,0 +1,36 @@ > > +/* > > + * Register definition file for Samsung MFC V10.x Interface (FIMV) driver > > + * > > + * Copyright (c) 2017 Samsung Electronics Co., Ltd. > > + * http://www.samsung.com/ > > + * > > + * This program is free software; you can redistribute it and/or modify > > + * it under the terms of the GNU General Public License version 2 as > > + * published by the Free Software Foundation. > > + */ > > + > > +#ifndef _REGS_MFC_V10_H > > +#define _REGS_MFC_V10_H > > + > > +#include <linux/sizes.h> > > +#include "regs-mfc-v8.h" > > + > > +/* MFCv10 register definitions*/ > > +#define S5P_FIMV_MFC_CLOCK_OFF_V10 0x7120 > > +#define S5P_FIMV_MFC_STATE_V10 0x7124 > > + > > +/* MFCv10 Context buffer sizes */ > > +#define MFC_CTX_BUF_SIZE_V10 (30 * SZ_1K) /* 30KB */ > > +#define MFC_H264_DEC_CTX_BUF_SIZE_V10 (2 * SZ_1M) /* 2MB */ > > +#define MFC_OTHER_DEC_CTX_BUF_SIZE_V10 (20 * SZ_1K) /* 20KB */ > > +#define MFC_H264_ENC_CTX_BUF_SIZE_V10 (100 * SZ_1K) /* 100KB */ > > +#define MFC_OTHER_ENC_CTX_BUF_SIZE_V10 (15 * SZ_1K) /* 15KB */ > > + > > +/* MFCv10 variant defines */ > > +#define MAX_FW_SIZE_V10 (SZ_1M) /* 1MB */ > > +#define MAX_CPB_SIZE_V10 (3 * SZ_1M) /* 3MB */ > > +#define MFC_VERSION_V10 0xA0 > > +#define MFC_NUM_PORTS_V10 1 > > + > > +#endif /*_REGS_MFC_V10_H*/ > > + > > diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc.c > > b/drivers/media/platform/s5p-mfc/s5p_mfc.c > > index bb0a588..a043cce 100644 > > --- a/drivers/media/platform/s5p-mfc/s5p_mfc.c > > +++ b/drivers/media/platform/s5p-mfc/s5p_mfc.c > > @@ -1542,6 +1542,33 @@ static int s5p_mfc_resume(struct device *dev) > > .num_clocks = 3, > > }; > > > > +static struct s5p_mfc_buf_size_v6 mfc_buf_size_v10 = { > > + .dev_ctx = MFC_CTX_BUF_SIZE_V10, > > + .h264_dec_ctx = MFC_H264_DEC_CTX_BUF_SIZE_V10, > > + .other_dec_ctx = MFC_OTHER_DEC_CTX_BUF_SIZE_V10, > > + .h264_enc_ctx = MFC_H264_ENC_CTX_BUF_SIZE_V10, > > + .other_enc_ctx = MFC_OTHER_ENC_CTX_BUF_SIZE_V10, > > +}; > > + > > +static struct s5p_mfc_buf_size buf_size_v10 = { > > + .fw = MAX_FW_SIZE_V10, > > + .cpb = MAX_CPB_SIZE_V10, > > + .priv = &mfc_buf_size_v10, > > +}; > > + > > +static struct s5p_mfc_buf_align mfc_buf_align_v10 = { > > + .base = 0, > > +}; > > + > > +static struct s5p_mfc_variant mfc_drvdata_v10 = { > > + .version = MFC_VERSION_V10, > > + .version_bit = MFC_V10_BIT, > > + .port_num = MFC_NUM_PORTS_V10, > > + .buf_size = &buf_size_v10, > > + .buf_align = &mfc_buf_align_v10, > > + .fw_name[0] = "s5p-mfc-v10.fw", > > Is firmware file publicly available?

I used BIT(5) in case someone upstreams MFCv9 they can use BIT(4) in order to maintain the sequence order as before. Thank you for the review.
