Well, I list the ARCHs related to the change file, do not include 
cris,ia64,mn10300
and openrisc, which ioremap is not the same as ioremap_nocache, as discussed in 
cover
letter. So please let me know if I need update the comment.

[PATCH v3 18/27] pinctrl: replace devm_ioremap_nocache with devm_ioremap

[Yisheng Xie]

Default ioremap is ioremap_nocache, so devm_ioremap has the same
function with devm_ioremap_nocache, which can just be killed to
save the size of devres.o

This patch is to use use devm_ioremap instead of devm_ioremap_nocache,
which should not have any function change but prepare for killing
devm_ioremap_nocache.

[PATCH v3 18/27] pinctrl: replace devm_ioremap_nocache with devm_ioremap

[Yisheng Xie]

Default ioremap is ioremap_nocache, so devm_ioremap has the same
function with devm_ioremap_nocache, which can just be killed to
save the size of devres.o

This patch is to use use devm_ioremap instead of devm_ioremap_nocache,
which should not have any function change but prepare for killing
devm_ioremap_nocache.
