Author: Alan Carvalho de Assis <acassis@gmail.com> Verify all .c and .h against nxstyle, fixed the Mixed cases Author: Alin Jerpelea <alin.jerpelea@sony.com> cxd56xx improvements (#48) * arch: cxd56xx: Add size limitation for I2C SCU xfer This is a fw restriction, unroll loop because it can be transfer up to 16 bytes. * arch: cxd56xx: Fix lack of leave_critical_section add the missing leave_critical_section * arch: cxd56xx: Remove unnecessary file this header is duplicate and we can remove it * arch: cxd56xx: Cosmetic change remove space after function * arch: cxd56xx: update topreg registers the topreg registers are updated to match the cxd5602 HW * arch: cxd56xx: Add voltage setting for low battery notification Add voltage setting for low battery notification * arch: cxd56xx: Improve perfomance of SD card Improve a problem that the clock of SD Host Controller is lower than the expected value in SDR25 transfer mode. * arch: cxd56xx: Cosmetic changes cleanup to comply with coding standard * boards: cxd56xx: Cosmetic changes updates to comply with coding standard * boards: cxd56xx: Fix SD card cannot mount issue SD card cannot mount when connecting and disconnecting three times or more due to wrong state of parameter 'initialized'. This change enables to skip swtching initialized state when mount failed.
