| |
SH_TIMER_CMT will use IO memory features which needs HAS_IOMEM, so need depend on it. The related error (with allmodconfig under um):
CC drivers/clocksource/sh_cmt.o drivers/clocksource/sh_cmt.c: In function 'sh_cmt_map_memory': drivers/clocksource/sh_cmt.c:920:2: error: implicit declaration of function 'ioremap_nocache' [-Werror=implicit-function-declaration] cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem)); ^ drivers/clocksource/sh_cmt.c:920:15: warning: assignment makes pointer from integer without a cast [enabled by default] cmt->mapbase = ioremap_nocache(mem->start, resource_size(mem)); ^ drivers/clocksource/sh_cmt.c: In function 'sh_cmt_setup': drivers/clocksource/sh_cmt.c:1034:2: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration] iounmap(cmt->mapbase); ^
