Add readl() and writel() for 'PM_' macros, just like another areas have done within unicored32, or will cause compiling issue. The related error (allmodconfig for unicored32): CC arch/unicore32/kernel/clock.o arch/unicore32/kernel/clock.c: In function 'clk_set_rate': arch/unicore32/kernel/clock.c:182: warning: initialization makes integer from pointer without a cast arch/unicore32/kernel/clock.c:204: error: lvalue required as left operand of assignment arch/unicore32/kernel/clock.c:206: error: lvalue required as left operand of assignment arch/unicore32/kernel/clock.c:207: error: invalid operands to binary & (have 'void *' and 'long unsigned int') make[1]: *** [arch/unicore32/kernel/clock.o] Error 1 make: *** [arch/unicore32/kernel] Error 2 Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Acked-by: Xuetao Guan <gxt@mprc.pku.edu.cn> Signed-off-by: Xuetao Guan <gxt@mprc.pku.edu.cn>
