** Description changed: SRU For Bionic [Impact] Larger EEPROM devices that use 16-bit addresses couldn't be accessed. [Fix] The commit is from https://patchwork.ozlabs.org/patch/545292/ Unfortunately, this commit doesn't get into mainline in the end, so I migrate the commit to latest kernel and finally get it merged. https://lkml.org/lkml/2020/4/24/635 [Test] Verified on Eurotech's platforms. [Regression Potential] Low, this patch only changes the behavior of the device which has AT24_FLAG_ADDR16 flag and change the page_size to 64 if the device name is 24c256. ===================================== SRU For Focal + [Impact] Larger EEPROM devices that use 16-bit addresses couldn't be accessed. [Fix] - Clear cherry pick from below - https://lkml.org/lkml/2020/4/24/635 + Clear cherry pick from linux-next + 82f25bd73c0b regmap-i2c: add 16-bit width registers support [Test] Verified on Eurotech's platforms. [Regression Potential] Low, this patch provides new access functions for 16-bit registers, shouldn't affect any other devices which are already working well.
