From: Javen Xu <redacted> This patch adds support for chip RTL8125cp. Its XID is 0x708. We apply different and firmware for RTL8125cp. Signed-off-by: Javen Xu <redacted> --- v2: This patch fix one mistake on phy_modify_paged(phydev, 0xa43, 0x10, 0x0000, 0x1001) which is phy_modify_paged(phydev, 0xa43, 0x00, 0x0000, 0x1001) on patch v1. v3: Set phy_modify_paged(phydev, 0xa43, 0x10, 0x0000, 0x0003), bit 0 means 'link speed 10m PLL OFF', bit 1 means 'ALDPS PLL OFF', bit 2 means 'ENABLE ALDPS', bit 12 means 'ALDPS XTAL OFF'.
If you know what these bits mean, why not add
#define RTL8125CP_LINK_SPEED_10M_PLL_OFF BIT(0)
#define RTL8125CP_ALDPS_PLL_OFF BIT(1)
etc.
