mtd: rawnand: meson: stop supporting legacy clocks

2022-09-21T08:38:47Z

meson NFC driver only uses common clock interfaces, which triggers kernel test robot errors when using legacy clocks with HAVE_LEGACY_CLK on.

mtd: rawnand: omap2: Actually prevent invalid configuration and build error

2022-03-07T16:46:54Z

The root of the problem is that we are selecting symbols that have dependencies. This can cause random configurations that can fail. The cleanest solution is to avoid using select. This driver uses interfaces from the OMAP_GPMC driver so we have to depend on it instead.

2022-01-25T09:32:07Z

We need to select MEMORY as well otherwise OMAP_GPMC will not be built. For simplicity let's select MEMORY and OMAP_GPMC unconditionally as this driver depends on OMAP_GPMC driver and uses symbols from there.

mtd: rawnand: brcmnand: Add BCMA shim

2022-01-23T15:37:19Z

Add a BCMA shim to allow us to register the brcmnand driver using the BCMA bus which provides indirect memory mapped access to SoC registers. There are a number of registers that need to be byte swapped because they are natively big endian, coming directly from the NAND chip, and there is no bus interface unlike the iProc or STB platforms that performs the byte swapping for us.
