1 Devicetree binding for regmap
7 native-endian: See common-properties.txt for a definition
10 Regmap defaults to little-endian register access on MMIO based
11 devices, this is by far the most common setting. On CPU
12 architectures that typically run big-endian operating systems
13 (e.g. PowerPC), registers can be defined as big-endian and must
14 be marked that way in the devicetree.
16 On SoCs that can be operated in both big-endian and little-endian
17 modes, with a single hardware switch controlling both the endianness
18 of the CPU and a byteswap for MMIO registers (e.g. many Broadcom MIPS
19 chips), "native-endian" is used to allow using the same device tree
23 Scenario 1 : a register set in big-endian mode.
