$attributeCode = ‘you_attribute_code’;
$attribute = $this->eavConfig->getAttribute('catalog_product', $attributeCode);

->joinLeft(
array('value_table' => $itemCollection->getTable('catalog_product_entity_int')),
'main_table.option_id=value_table.value AND main_table.attribute_id=value_table.attribute_id', 'entity_id')
->reset(\Zend_Db_Select::COLUMNS)
->columns(array('main_table.option_id',new \Zend_Db_Expr('COUNT(value_table.entity_id)')))
