Merge tag 'memory-controller-drv-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers
Memory controller drivers for v5.19, part two 1. Cleanup: simplify platform_get_resource() calls by using devm_platform_get_and_ioremap_resource() helper. 2. OMAP: allow building omap-gpmc as module and make it visible (it is not selected by platform anymore). * tag 'memory-controller-drv-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: memory: omap-gpmc: Allow building as a module memory: omap-gpmc: Make OMAP_GPMC config visible and selectable memory: renesas-rpc-if: simplify platform_get_resource_byname() memory: brcmstb_dpfe: simplify platform_get_resource_byname() memory: tegra: mc: simplify platform_get_resource() memory: ti-emif-pm: simplify platform_get_resource() memory: ti-emif: simplify platform_get_resource() memory: emif: simplify platform_get_resource() memory: da8xx-ddrctl: simplify platform_get_resource() Link: https://lore.kernel.org/r/20220503070652.54091-1-krzysztof.kozlowski@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>
