From: Olliver Schinagl Date: Thu, 3 Dec 2015 16:49:28 +0000 (+0100) Subject: sunxi: twi: Enable clocks on sun7i X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=887e2fd9daf0be92395046b85efc38af0c6ccda1;p=u-boot.git sunxi: twi: Enable clocks on sun7i Commit 6c739c5d added code to enable i2c bus 4 and 5 on the sun7i SoC but forgot to extend the range check in clock_twi_onoff, resulting in the clock not getting enabled. The range-check is not needed at all, since clock_twi_onoff only gets called with such high indexes when CONFIG_I2C3_ENABLE / CONFIG_I2C4_ENABLE is set and Kconfig already only allows these on sun6i / sun7i. This commit removes the range-check all together fixing i2c bus 4 and 5 not working on sun7i.
