Previously, the Card Detect (CD) and Write Protect (WP) pins shared the same reverse polarity setting in the configuration space. This meant both signals were reversed together, without the ability to configure them individually. This patch introduces two new parameters: sd_cd_reverse_en – enable reverse polarity for the CD pin. sd_wp_reverse_en – enable reverse polarity for the WP pin. With this change, the controller can now support: 1.Reversing both CD and WP pins together (original behavior). 2.Reversing CD and WP pins separately (newly added behavior), if supported by the configuration space. This provides greater flexibility when dealing with devices that have independent polarity requirements for CD and WP pins.
