From 4aa8c0694c731e03eb660b92a3afe14859142381 Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Wed, 2 Apr 2014 18:09:07 +0800 Subject: [PATCH] regmap: implement LE formatting/parsing for 16/32-bit values. Allow busses to request little endianness formatting and parsing for 16- and 32-bit values. This will be useful to support regmap-mmio. For the following the scenarios using the regmap-mmio, for example: Index CPU Device Endianess flag for values ---------------------------------------------------------- 1 LE LE REGMAP_ENDIAN_DEFAULT/NATIVE 2 LE BE REGMAP_ENDIAN_BIG 3 BE BE REGMAP_ENDIAN_DEFAULT/NATIVE 4 BE LE REGMAP_ENDIAN_LITTLE For one device driver, which will support all the cases above, needs two boolean properties in DT node like: 'big-endian' for case 2 and 'little-endian' for case 4, and for cases 1 and 3 they all will be absent.
