EMIF supports, based on its revision, one or more of LPDDR2/DDR2/DDR3 protocols. Add the basic infrastructure for EMIF driver that includes driver registration, probe, parsing of platform data etc. Signed-off-by: Aneesh V Reviewed-by: Santosh Shilimkar Reviewed-by: Benoit Cousson [santosh.shilimkar@ti.com: Moved to drivers/memory from drivers/misc] Signed-off-by: Santosh Shilimkar Tested-by: Lokesh Vutla Signed-off-by: Greg Kroah-Hartman --- drivers/memory/Kconfig | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 drivers/memory/Kconfig (limited to 'drivers/memory/Kconfig') diff --git a/drivers/memory/Kconfig b/drivers/memory/Kconfig new file mode 100644 index 000000000000..b08327cca0e5 --- /dev/null +++ b/drivers/memory/Kconfig @@ -0,0 +1,22 @@ +# +# Memory devices +# + +menuconfig MEMORY + bool "Memory Controller drivers" + +if MEMORY + +config TI_EMIF + tristate "Texas Instruments EMIF driver" + select DDR + help + This driver is for the EMIF module available in Texas Instruments + SoCs.
