[RFT 00/13] iomap: Constify ioreadX() iomem argument

2020-01-07 Thread Krzysztof Kozlowski
Hi, The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not. It seems there is nothing really stopping all of them to take pointer to const. Patchset was really tested on all affected architectures. Build testing is in progress -

The ioreadX() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not. Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among
