2019-10-07	soc: qcom: ocmem: add missing includes	Brian Masney
	The kbuild bot reported the following compiler errors when compiling on MIPS with CONFIG_QCOM_OCMEM disabled: In file included from <command-line>:0:0: >> include/soc/qcom/ocmem.h:43:49: warning: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration static inline struct ocmem of_get_ocmem(struct device dev) ^~~~~~ include/soc/qcom/ocmem.h: In function 'of_get_ocmem': >> include/soc/qcom/ocmem.h:45:9: error: implicit declaration of function 'ERR_PTR' [-Werror=implicit-function-declaration] return ERR_PTR(-ENODEV); ^~~~~~~ >> include/soc/qcom/ocmem.h:45:18: error: 'ENODEV' undeclared (first use in this function) return ERR_PTR(-ENODEV); Add the proper includes to fix the compiler errors.

2019-10-07	soc: qcom: add OCMEM driver	Brian Masney
	The OCMEM driver handles allocation and configuration of the On Chip MEMory that is present on some Snapdragon SoCs. Devices which have OCMEM do not have GMEM inside the GPU core, so the GPU must instead use OCMEM to be functional. Since the GPU is currently the only OCMEM user with an upstream driver, this is just a minimal implementation sufficient for statically allocating to the GPU it's chunk of OCMEM. This driver currently does not read the gmu-sram node that is described in the device tree bindings. The starting memory address of the GPU's reserved memory region is hardcoded to zero to match what the hardware expects. The driver can be updated to read the reserved memory regions from device tree once other users of OCMEM are added upstream.
