Subject: [PATCH] ARM: mach-shmobile: sh7377 Enable SDIO IRQs
Date: Thu, 06 Jan 2011 10:41:09 +0000 [thread overview]
Message-ID: <20110106104109.7697.96086.sendpatchset@t400s> (raw)
From: Magnus Damm <damm@opensource.se>
This patch enables interrupt generation for SDIO IRQs
of the SDHI block on the sh7377 aka G4 processor. Use
together with a recent SDHI driver using TMIO_MMC_SDIO_IRQ
and with the MMC_CAP_SDIO_IRQ flag in the board code.
The G4EVM specific SDHI platform data is also updated to
flag SDIO capabilities.
