2013-05-08	6a5e4f0 Browse files » MCI/MXS: fix signed/unsigned mismatch ... Using the MXS MCI driver with an eight bit capable eMMC results into the 'devinfo' message the interface uses '0' bits for data transfer: barebox:/ devinfo mxs_mci0 resources: num : 0 start : 0x80034000 size : 0x00002000 driver: mxs_mci bus: platform Interface Min. bus clock: 1476 Hz Max. bus clock: 48000000 Hz Current bus clock: 24000000 Hz Bus width: 0 bit The eight bit interface width is stored internally as value '2'. And a two bit '2' ends up into 0xfffffffe when used as an array index. Using an unsigned field instead fixes this issue: barebox:/ devinfo mxs_mci0 resources: num : 0 start : 0x80034000 size : 0x00002000 driver: mxs_mci bus: platform Interface Min. bus clock: 1476 Hz Max. bus clock: 48000000 Hz Current bus clock: 24000000 Hz Bus width: 8 bit Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Juergen Beisert authored on 8 May 2013 Sascha Hauer committed on 8 May 2013
