2016-08-08 | memory: atmel-ebi: use PTR_ERR_OR_ZERO() to simplify the code | Wei Yongjun | |
Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR. Generated by coccinelle. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> | |||
2016-06-21 | memory: atmel-ebi: make it explicitly non-modular | Paul Gortmaker | |
The Kconfig currently controlling compilation of this code is: drivers/memory/Kconfig:config ATMEL_EBI drivers/memory/Kconfig: bool "Atmel EBI driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the few remaining modular references, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2016-06-02 | memory: add Atmel EBI (External Bus Interface) driver | Boris Brezillon | |
The EBI (External Bus Interface) is used to access external peripherals (NOR, SRAM, NAND, and other specific devices like ethernet controllers). Each device is assigned a CS line and an address range and can have its own configuration (timings, access mode, bus width, ...). This driver provides a generic DT binding to configure a device according to its requirements. For specific device controllers (like the NAND one) the SMC timings should be configured by the controller driver through the matrix and smc syscon regmaps.
