Start replacing the below occurences with the newer API: - (devm_)platform_get_resource + devm_ioremap_resource - (devm_)platform_get_resource + (devm_)ioremap - platform_get_resource_byname + devm_ioremap Move all these occurences to uses devm_platform_ioremap_resource instead. This is v2 of the series. Changes from v1 [1]: - Mostly fix the compilation errors :( What had passed locally happened to be the wrong config with most drivers not enabled. - Clarify the TODO item in the GPU section of Documentation for anyone who wants to do it in future. - Drop meson patch from discussion in v1 - Drop rockchip patch as well. Offline discussion with Maxime led to the conclusion that using devm_platform_get_and_ioremap_resource() would be a better approach in that source file. Not adding that change as part of this series, can be addressed separately.
