Hi Biju, Thank you for the patch.

As commented in similar patches, please try to explain in the commit message the reason *why* the change is good and/or needed. It's quite straightforward for me to understand the change to i2c_get_match_data() given the discussions we've had recently, but it would be more difficult without that background information. > Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> > --- > drivers/gpu/drm/bridge/adv7511/adv7511.h | 6 +- > drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 68 +++++++++++--------- > drivers/gpu/drm/bridge/adv7511/adv7533.c | 4 +- > 3 files changed, 46 insertions(+), 32 deletions(-) > > diff --git a/drivers/gpu/drm/bridge/adv7511/adv7511.h b/drivers/gpu/drm/bridge/adv7511/adv7511.h > index 17445800248d..59e8ef10d72e 100644 > --- a/drivers/gpu/drm/bridge/adv7511/adv7511.h > +++ b/drivers/gpu/drm/bridge/adv7511/adv7511.h > @@ -333,6 +333,10 @@ enum adv7511_type { > > #define ADV7511_MAX_ADDRS 3 > > +struct adv7511_chip_info { > + enum adv7511_type type; > +}; > + > struct adv7511 { > struct i2c_client *i2c_main; > struct i2c_client *i2c_edid; > @@ -377,7 +381,7 @@ struct adv7511 { > u8 num_dsi_lanes; > bool use_timing_gen; > > - enum adv7511_type type; > + const struct adv7511_chip_info *info; > struct platform_device *audio_pdev; > > struct cec_adapter *cec_adap; > diff --git a/drivers/gpu/drm/bridge/adv7511/adv7511_drv.c b/drivers/gpu/drm/bridge/adv7511/adv7511_drv.c > index 2611afd2c1c1..013d8d640ef4 100644 > --- a/drivers/gpu/drm/bridge/adv7511/adv7511_drv.c > +++ b/drivers/gpu/drm/bridge/adv7511/adv7511_drv.c > @@ -354,7 +354,7 @@ static void __adv7511_power_on(struct adv7511 *adv7511) > * first few seconds after enabling the output.

Ok will add the info.

Add struct adv7511_chip_info to handle hw differences between various chips rather checking against the 'type' variable in various places. Replace 'adv->type'->'info->type' by moving variable 'type' from struct adv7511 to struct adv7511_chip_info. Replace of_device_get_match_data() and ID lookup for retrieving match data with i2c_get_match_data() by adding adv7511_chip_info as device data for both OF and ID tables.
