David Gow	1bea2a937d	soc: litex: Properly depend on HAS_IOMEM ... The LiteX SOC controller driver makes use of IOMEM functions like devm_platform_ioremap_resource(), which are only available if CONFIG_HAS_IOMEM is defined. This causes the driver to be enable under make ARCH=um allyesconfig, even though it won't build. By adding a dependency on HAS_IOMEM, the driver will not be enabled on architectures which don't support it.

Stafford Horne	e6dc077b7d	soc: litex: Fix compile warning when device tree is not configured ... The test robot reported: drivers/soc/litex/litex_soc_ctrl.c:143:34: warning: unused variable 'litex_soc_ctrl_of_match' [-Wunused-const-variable] static const struct of_device_id litex_soc_ctrl_of_match[] = { ^ 1 warning generated. As per the random config device tree is not configured causing the litex_soc_ctrl_of_match match list to not be used. This would usually mean that we cannot even use this driver as it depends on device tree, but as we also have COMPILE_TEST configured we allow it. Fix the warning by surrounding the unused variable with an ifdef CONFIG_OF. Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Stafford Horne <shorne@gmail.com>	2021-01-14 09:34:00 +09:00
