Subject: [PATCH net-next v2 09/14] net: macb: change caps helpers signatures
Date: Fri, 10 Apr 2026 21:51:57 +0200	[thread overview]
Message-ID: <20260410-macb-context-v2-9-af39f71d40b6@bootlin.com> (raw)
In-Reply-To: <20260410-macb-context-v2-0-af39f71d40b6@bootlin.com>

For parallel MACB context to start become a reality, many functions will
soon not have access to `struct macb *bp`. Those will still have access
to caps through ctx->info->caps.

Change all caps helpers signatures, from taking `struct macb *bp` to
taking `u32 caps`.

Function list:

   macb_is_gem()
   gem_has_ptp()
   macb_dma64()
   macb_dma_ptp()
   macb_dma_desc_get_size()
   macb_set_addr()
   macb_get_addr()

Note: drop macb_64b_desc(bp, ...) parameter; it is unused and it must
be dropped as macb_{set,get}_addr() call macb_64b_desc().
