From: Parker Newman <pnewman@xxxxxxxxxxxxxxx> This series of patches replaces the custom 93cx6 EEPROM read functions in the 8250_exar driver with the eeprom_93cx6 driver. This removes duplicate code and improves code readability. In order to use the eeprom_93cx6 driver a quirk needed to be added to add an extra clock cycle before reading from the EEPROM. This is similar to the quirk in the eeprom_93xx46 driver. More details in associated patch and mailing list discussion with Andy Shevchenko about these changes: Link: https://lore.kernel.org/linux-serial/Ztr5u2wEt8VF1IdI@xxxxxxxxxxxxxxxxxx/ Changes in v2: - Dropped patch 3 "misc: eeprom: eeprom_93cx6: Replace printk(KERN_ERR...) with pr_err()". - Moved Kconfig change into main patch. - Moved quirk define into struct eeprom_93cx6. - Moved quirk check function into eeprom_93cx6.h. - Refactored cti_read_osc_freq() based on feedback. - Minor commit message formatting fixes. Changes in v3: - Rebased to v6.12-rc1. - Minor commit message rewording. - Replace CTI_EE_MASK_OSC_FREQ_UPPER/LOWER with a single define in patch 4. - Add patch 5 from Andy Shevchenko: "serial: 8250_exar: Group CTI EEPROM offsets by device".
