From 1e700846d6facd4e42a56978a2f3d9379ec788d0 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Fri, 7 Feb 2014 22:20:39 +0100 Subject: misc: eeprom: sunxi: Change compatibles The Allwinner A10 compatibles were following a slightly different compatible patterns than the rest of the SoCs for historical reasons. Change the compatibles to match the other pattern in the SID driver for consistency.

So while being part of the peripheral, it should not be part of the genpool controlling the sram. Therefore add the option to define reserved regions as subnodes of the sram-node similar to defining reserved global memory regions.
