2017-01-19memory: aemif: allow passing device lookup table as platform dataBartosz Golaszewski
TI aemif driver creates its own subnodes of the device tree in order to guarantee that all child devices are probed after the AEMIF timing parameters are configured. Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup but nodes created from within the aemif driver can't access the lookup table. Create a platform data structure that holds a pointer to of_dev_auxdata so that we can use it with of_platform_populate().

2016-08-08memory: omap-gpmc: allow probe of child nodes to failJohan Hovold
A recent commit (inadvertently?) changed how failed probe of a gpmc child node was handled. Instead of proceeding with setting up any other children as before, a single error now aborts the whole process. This change broke networking on some Overo boards due to probe failing for an unrelated nand node. This second issue should obviously be fixed, but let's restore the old behaviour of allowing child-node probe to fail to avoid further similar breakage on other systems.

2016-06-21memory: atmel-ebi: make it explicitly non-modularPaul 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.

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.

2016-06-21memory/mediatek: add support for mt2701Honghui Zhang
Mediatek SMI has two generations of HW architecture, mt8173 uses the second generation of SMI HW while mt2701 uses the first generation HW of SMI. There's slight differences between the two generations, for generation 2, the register which control the iommu port access PA or IOVA is at each larb's register base. But for generation 1, the register is at smi ao base(smi always on register base). Besides that, the smi async clock should be prepared and enabled for SMI generation 1 HW to transform the smi clock into emi clock domain, but is not needed for SMI generation 2. This patch add SMI driver for mt2701 which use generation 1 SMI HW. Signed-off-by: Honghui Zhang <honghui.zhang@mediatek.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>

The Kconfig currently controlling compilation of this code is: memory/samsung/Kconfig:config EXYNOS_SROM memory/samsung/Kconfig: bool "Exynos SROM controller driver" if COMPILE_TEST ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. 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.

2016-06-16memory: omap-gpmc: Fix omap gpmc EXTRADELAY timingOcquidant, Sebastien
In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY is overwritten by the WEEXTRADELAY value from the device tree and GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device tree. As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.

2016-06-14memory: tegra: mc: Add missing of_node_put()Amitoj Kaur Chawla
for_each_child_of_node() performs an of_node_get() on each iteration, so to break out of the loop an of_node_put() is required. Found using Coccinelle. The semantic patch used for this is as follows: // <smpl> @@ expression e; local idexpression n; @@ for_each_child_of_node(..., n) { ... when != of_node_put(n) when != e = n ( return n; | + of_node_put(n); ? return ...; ) ... } // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
