Hi,
Thank you for this work. If you have a time, could you update sh_i2c using set/clrbits functions? these functions is included in asm/io.h.
For example, you can change from writeb(readb(&base->iccr) & ~SH_I2C_ICCR_ICE, &base->iccr); to clrbits_8(&base->iccr, SH_I2C_ICCR_ICE); .
Best regards, Nobuhiro

Hi, Iwamatsu-san Hello, Heiko
Iwamatu-san, thank you for review. This is v2 patch for sh_i2c. Now "i2c dev" and "i2c probe" also work properly on KZM-A9-GT board. I think this modification is common for R-mobile, but I have SH73A0 document only. Iwamatu-san, please review this.
This patch set is based on arm/rmobile branch of u-boot-sh.git.
