From f696a7ee254f7e4e96bd1a21addd1315169b8a8a Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Fri, 1 Nov 2019 15:31:02 +0200 Subject: iwlwifi: yoyo: add PCI config space region type Add a new region type that allows us to dump the PCI config space. This is mostly the same as dumping a memory region, but reading from the device's config space instead. In order to make this generic and independent of the trans type, we make a function called iwl_dump_ini_config_iter() that calls a new op in the transport to read its config space.
