I'm having problems with software reset when adapting TJA1120 driver (from Linux 6.6) to Linux 5.15 with error code -110, I'm not sure about the cause as well as I don't know how to fix this problem.
I refer to this post NXP_C45_TJA11XX Driver Soft Reset Issue, made changes to nxp_c45_soft_reset, but it has no effect, the code is as follows.
static int nxp_c45_soft_reset(struct phy_device *phydev)
{
int ret;
ret = phy_write_mmd(phydev, MDIO_MMD_VEND1, VEND1_DEVICE_CONTROL,
DEVICE_CONTROL_RESET);
if (ret)
return ret;
usleep_range(2000, 2050);
return phy_read_mmd_poll_timeout(phydev, MDIO_MMD_VEND1,
VEND1_DEVICE_CONTROL, ret,
!(ret & DEVICE_CONTROL_RESET), 20000,
240000, true);
}:Error.
