Subject[PATCH v4 01/11] mfd: syscon: Add atmel-matrix registers definition
Date
AT91 SoCs have a memory range reserved for internal bus configuration.
Expose those registers so that drivers can make use of the matrix syscon
declared in at91 DTs.

Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
Acked-by: Lee Jones <lee.jones@linaro.org>

Changes since v3:
- added AT91_MATRIX_USBPUCR_PUON definition
- removed useless macros (those directly returning SoC specific register
offsets)
