From 5d60e500541ed154112809627f12d86056ac5f09 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 20 Nov 2013 00:31:06 -0800 Subject: mmc: tmio: add new TMIO_MMC_HAVE_HIGH_REG flags The accessibility checking method to the higher register was added by 69d1fe18e92afb (mmc: tmio: only access registers above 0xff, if available) But, it doesn't care 32bit register. It is impossible to calculate it from the resource size, since there is 16/32 bit register IP (e.g. VERSION is located on 0xe2 if 16bit register, but it is located on 0x1c4 if 32bit register). This patch adds new TMIO_MMC_HAVE_HIGH_REG flags, tmio_mmc driver has it, and sh_mobile_sdhi doesn't have it today.
