Subject: [PATCH v3 16/27] ata: start separating SATA specific code from libata-core.c
Date: Thu, 27 Feb 2020 19:22:15 +0100 [thread overview]
Message-ID: <20200227182226.19188-17-b.zolnierkie@samsung.com> (raw)
In-Reply-To: <20200227182226.19188-1-b.zolnierkie@samsung.com>
Start separating SATA specific code from libata-core.c:
* move following functions to libata-sata.c:
- ata_tf_to_fis()
- ata_tf_from_fis()
- sata_link_scr_lpm()
- ata_slave_link_init()
- sata_lpm_ignore_phy_events()
* group above functions together in <linux/libata.h>
* include libata-sata.c in the build when CONFIG_SATA_HOST=y
