[PATCH AUTOSEL 4.19 027/209] ata: ahci_brcm: Match BCM63138 compatible strings

[Sasha Levin]

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit fb8506f15f2e394f5f648575cf48a26e8744390c ]

Match the "brcm,bcm63138-ahci" compatible string in order to allow this
driver to probe on such platforms.

[PATCH AUTOSEL 4.19 028/209] ata: ahci_brcm: Allow using driver or DSL SoCs

[Sasha Levin]

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit 7fb44929cb0e5cdcde143e1ca3ca57b5b8247db0 ]

The Broadcom STB AHCI controller is the same as the one found on DSL
SoCs, so we will utilize the same driver on these systems as well.

[PATCH AUTOSEL 4.19 086/209] ata: ep93xx: Use proper enums for directions

[Sasha Levin]

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit 6adde4a36f1b6a562a1057fbb1065007851050e7 ]

Clang warns when one enumerated type is implicitly converted to another.

Use the equivalent valued enums from the expected type so that Clang no
longer warns about a conversion.

DMA_TO_DEVICE = DMA_MEM_TO_DEV = 1
DMA_FROM_DEVICE = DMA_DEV_TO_MEM = 2
