Subject: [PATCH 05/11] ARM: shmobile: koelsch legacy: Add MSIOF support
From: Geert Uytterhoeven <geert+renesas@...ux-m68k.org>
Add MSIOF resources, platform data, platform device, pinctrl, and SPI
child device.
- Platform device numbering is 1-based for compatibility with the BSP,
as QSPI uses zero.
- Only MSIOF0 is in use, and thus registered. Its bus contains a single
device (a Renesas R2A11302FT PMIC).
Based on patches from Takashi Yoshii <takasi-y@....dti.ne.jp>
Signed-off-by: Geert Uytterhoeven <geert+renesas@...ux-m68k.org>
