First you can add my Acked-by: Gregory CLEMENT <gregory.clement@bootlin.com> Then as the second patch is a fix, you should add the fix tag: "Fixes: 5715092a458c ("pinctrl: armada-37xx: Add gpio support") " as well as the 'CC: <stable@vger.kernel.org>" tags. But your change in the first patch made this second patch more difficult to backport. Actually, when I wrote "_update_reg" I was thinking to the update of the variable, whereas with a function named "_calculate_reg" I am expecting having the result as a return of the function. However I am not against your change, as I pointed my main concern is about the backport of the patch to the stable branch. Maybe you could change the order of those 2 patches?

Good points. Will do both. > Actually, when I wrote "_update_reg" I was thinking to the update of the > variable, whereas with a function named "_calculate_reg" I am expecting > having the result as a return of the function. Understand. I can see the ambiguity in both names. How about "_update_reg_offset"? > Thanks, > > Gregory >
From: Patrick Williams <alpawi@amazon.com> The 37xx GPIO config registers are only 32 bits long and span 2 registers for the NB GPIO controller. The function to calculate the offset was missing the increase to the config register. I have tested both raw gpio access and interrupts using libgpiod utilities on an Espressonbin. The first patch is a simple rename of a function because the original name implied it was doing IO itself ("update reg"). This patch could be dropped if undesired. The second patch contains the fix for GPIOs 32+.
