The DE2 in Allwinner A64 SoC requires the SRAM C to be claimed to work.
This patchset adds the support of SRAM C in A64 for the sunxi-sram driver.
As the SRAM C controlling bit is a little different with other peripherals' SRAM controlling bit (inverted), a function value to register value remapping is added, which is also useful for the SRAM C1 (VE SRAM) on some SoCs.
Patch 1 is the device tree binding patch.
Patch 2 is a fix for the usage of the DE2 SRAM -- as it's claimed by a clock driver, and kernel are trying to probe the DE2 clock driver before probing sunxi-sram driver; this patch fixed probe defering when claiming SRAM region.
Patch 3 adds the remapping code.
Patch 4 adds necessary codes for A64 SRAM C.
Icenowy Zheng (4): dt-bindings: add binding for Allwinner A64 SRAM controller and SRAM C drivers: soc: sunxi: fix error processing on base address when claiming drivers: soc: sunxi: add support for remapping func value to reg value drivers: soc: sunxi: add support for A64 and its SRAM C
