2022-04-29memory: omap-gpmc: Make OMAP_GPMC config visible and selectableRoger Quadros1-1/+1
So far for armv7 TI platforms, GPMC was being selected by arch/arm/mach-* architecture Kconfig files. For K3 platforms, GPMC is no longer required for basic boot and cannot be always enabled by default by mach- Kconfig. We need a way for user (or board defconfig) to enable it if required so make OMAP_GPMC Kconfig option always visible. Drop COMPILE_TEST as build fails if IRQ_DOMAIN is not enabled.

2022-04-21memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual ModeGeert Uytterhoeven1-14/+46
HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only.

Commit 3e25f800afb8 ("memory: fsl_ifc: populate child devices without relying on simple-bus") was trying to replace the "simple-bus" compatible with explicit bus populate in the driver.

Function clk_bulk_prepare_enable() returns 0 for success or a negative number for error, although the common style for the callers is to check always for any non-zero return value (just like its implementation in clk.h does). Adjust the code to such coding style.

2021-12-22memory: omap-gpmc: Use platform_get_irq() to get the interruptLad Prabhakar1-7/+3
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq().
