| Subject: ata: ahci: Add Green Sardine vendor ID as board_ahci_mobile |
| |
| From: Mario Limonciello <mario.limonciello@amd.com> |
| |
| [ Upstream commit 1527f69204fe35f341cb599f1cb01bd02daf4374 ] |
| |
| AMD requires that the SATA controller be configured for devsleep in order |
| for S0i3 entry to work properly. |
| |
| commit b1a9585cc396 ("ata: ahci: Enable DEVSLP by default on x86 with |
| SLP_S0") sets up a kernel policy to enable devsleep on Intel mobile |
| platforms that are using s0ix. Add the PCI ID for the SATA controller in |
| Green Sardine platforms to extend this policy by default for AMD based |
| systems using s0i3 as well. |
