This patch adds platform data with a function for power
control to the SDHI driver. The idea is that board specific
code can provide their own functions so power can be enabled
and disabled for the sd-cards.

Needed by the Ecovec board.
Apply on top of the SDHI driver in the SuperH tree.

This patch adds support for SDHI power control to the
Ecovec board. Platform data and power control callbacks
for SDHI0 and SDHI1 are added. Power is by default off.

Depends on the SDHI power control patch.

Add sh7724 code to save and restore CPG state during

* [PATCH] sh: Break out SuperH PFC code

From: Magnus Damm @ 2009-11-27 7:38 UTC (permalink / raw)
To: linux-sh
From: Magnus Damm <damm@opensource.se>
This file breaks out the SuperH PFC code from
arch/sh/kernel/gpio.c + arch/sh/include/asm/gpio.h
to drivers/sh/pfc.c + include/linux/sh_pfc.h.
Similar to the INTC stuff. The non-SuperH specific
file location makes it possible to share the code
between multiple architectures.

From: Magnus Damm @ 2009-11-27 9:28 UTC (permalink / raw)
To: linux-sh
From: Magnus Damm <damm@opensource.se>
This patch improves the serial port communication quality
of port YC401 on the KFR2R09 board. With this fix serial
console is fine at 115200 - up and down keys now work as
expected. Thanks to Hirohide Yamasaki for this fix.
