memory: atmel-sdramc: remove the driver

2023-06-02T08:39:24Z

Driver does only clock request + enable for DDR clocks. DDR clocks are enabled by bootloader and need to stay that way in Linux. To avoid having these clocks disabled by clock subsystem in case there are no Linux consumers for them the clocks were marked as critical in clock drivers (in commit 68b3b6f1773d ("clk: at91: mark ddr clocks as critical")). With this, there is no need to have a separate driver that only does clock request + enable.

memory: atmel-sdramc: Fix missing clk_disable_unprepare in atmel_ramc_probe()

2022-12-27T08:53:52Z

The clk_disable_unprepare() should be called in the error handling of caps->has_mpddr_clk, fix it by replacing devm_clk_get and clk_prepare_enable by devm_clk_get_enabled.

memory: atmel-sdramc: fix a possible NULL dereference

2016-08-31T17:19:16Z

of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data. Signed-off-by: LABBE Corentin Signed-off-by: Alexandre Belloni

memory: atmel-sdramc: make it explicitly non-modular

2016-06-21T15:16:42Z

The Kconfig for this option is currently: config ATMEL_SDRAMC bool "Atmel (Multi-port DDR-)SDRAM Controller" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. An alternate init level might be worth considering at a later date. 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 was (or is now) contained at the top of the file in the comments.

memory: drop owner assignment from platform_drivers

2014-10-20T14:20:52Z

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

memory: add a driver for atmel ram controllers

2014-07-15T09:43:42Z

Atmel SoCs have one or multiple RAM controllers that need one or multiple clocks to run. This driver handle those clocks. Signed-off-by: Alexandre Belloni Signed-off-by: Maxime Ripard Acked-by: Nicolas Ferre
