Depends on the "Introduce get_vt8237_lpc() function" and
"Use get_vt8237_lpc() in vt8237_sb_enable_fid_vid()" patches.
This adds VT8237A specific VLINK/LPC init in vt8237r_early_smbus.c
I ran some tests and apparently both the
| /* So the chip knows we are on AMD. */
| pci_write_config8(devctl, 0x7c, 0x7f);
and
| /*
| * Allow SLP# signal to assert LDTSTOP_L.
| * Will work for C3 and for FID/VID change.
| */
| outb(0x1, VT8237R_ACPI_IO_BASE + 0x11);
in vt8237r_early_smbus.c are needed on VT8237A, otherwise I get a (non-fatal)
fid/vid change error on boot.
While vt8237a_vlink_init() in vt8237_ctrl.c is a modified vt8237r_vlink_init(),
vt8237a_init() in vt8237r_lpc.c is a modified vt8237s_init().
