The number 4 is dedicated on i.MX7ULP, but lpi2c will be reused on i.MX8, 4 is not valid. The seq number could be configured by alias node. The following patch will use i2c4 as the begin for i.MX7ULP. Signed-off-by: Peng Fan <peng.fan@nxp.com> --- drivers/i2c/imx_lpi2c.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
