[PATCH v3 8/8] ARM: shmobile: completely switch MMC interfaces on armadillo800eva-reference to DT
From: Guennadi Liakhovetski <hidden>
Date: 2013-01-23 16:37:51
Also in:
linux-sh
Subsystem:
arm port, arm/risc-v/renesas architecture, the rest · Maintainers:
Russell King, Geert Uytterhoeven, Magnus Damm, Linus Torvalds
Switch MMCIF, SDHI0 and SDHI1 to complete DT initialisation: use DT bindings to configure regulators, interface pins, card-detect GPIOs, various interface configuration parameters.
