From f02f8aee211a1fc035cd3f87af8a39126eda1c20 Mon Sep 17 00:00:00 2001 From: Ariel D'Alessandro Date: Mon, 7 Dec 2015 10:57:39 +0000 Subject: nvmem: NXP LPC18xx EEPROM memory NVMEM driver This commit adds support for NXP LPC18xx EEPROM memory found in NXP LPC185x/3x and LPC435x/3x/2x/1x devices. EEPROM size is 16384 bytes and it can be entirely read and written/erased with 1 word (4 bytes) granularity. The last page (128 bytes) contains the EEPROM initialization data and is not writable. Erase/program time is less than 3ms. The EEPROM device requires a ~1500 kHz clock (min 800 kHz, max 1600 kHz) that is generated dividing the system bus clock by the division factor, contained in the divider register (minus 1 encoded). EEPROM will be kept in Power Down mode except during read/write calls.
