Hi, Thanks for the update. I was thinking I should reply to your patch in the last month, but I was a little busy at the time and I forgot to do so...

And please add more description about the device in the commit message. We don't even know the full name of the vendor from your patch. I like the older version of your patch in that perspective. https://lore.kernel.org/all/1656426829-1008-3-git-send-email-shubhrajyoti.datta@xxxxxxxxxx/ And a link to the device datasheet would be also nice (if possible). > > drivers/gpio/gpio-pca9570.c | 39 +++++++++++++++++++++++++++++++++---- > 1 file changed, 35 insertions(+), 4 deletions(-) And I was also thinking that tpic2810 driver might be more appropriate then this pca9570 driver for a device with one command byte. Actually I had forked tpic2810 to create pca9570 to support a device without any command byte. Come to think of it, the two drivers may even be consolidated into a single generic one... What do you think? Thanks, Sungbo
