Here is v2 of SUNXI PS2 controller support patch-set as with v1.So as promised I've run this on an A10 board, with a small fix to the interrupt property in the sun4i.dtsi file this works as is. This means that the sun7i compat should be dropped, and the sun4i compat used everywhere. I've created 3 fixup patches to do this, note one also renames / moves the bindings file as it is in the wrong place. I've attached the 3 fixup patches, pleasesquash these into your existing patches before posting the next version. Thanks & Regards, Hansquoted
Changes in v2: 1. added default n depends on ARCH_SUNXI || COMPILE_TEST in Kconfig. 2. handled errors and free resources on errors. 3. used BIT(x), DIV_ROUND_UP macros. 4. corrected style errors. 5. added support for A10 also, A10 and A2 have same properties of PS2controller.quoted
