[Resending because I3C list was not added on all patches. Sorry!] I am currently working on upstreaming another I3C controller driver. As many others, it needs to ensure odd parity for a dynamically assigned address. The BSP version of the driver implemented a custom parity algorithm. Wondering why we don't have a generic helper for this in the kernel, I found that many I3C controller drivers all implement their version of handling parity. So, I sent out an RFC[1] moving the efficient implementation of the SPD5118 driver to a generic location. The series was well received, but the path for upstream was not clear. Because I need the implementation for my I3C controller driver and I3C is a prominent user of this new function, I got the idea of converting the existing I3C drivers and resend the series, suggesting this all goes upstream via I3C. Is this acceptable? The non-I3C patches have all the tags they need, only the I3C patches would need testing on hardware. A locally build-tested branch is here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i3c/get_parity Looking forward to comments...
