2020-09-01memory: samsung: exynos5422-dmc: rename timing register fields variablesKrzysztof Kozlowski
The driver has file-scope arrays defining fields of timing registers (e.g. struct timing_reg timing_row) and actual values for these registers per each OPP in state container (struct exynos5_dmc.timing_row). The meanings of these are different so use different names to avoid confusion.

2020-08-27memory: emif: Remove bogus debugfs error handlingDan Carpenter
Callers are generally not supposed to check the return values from debugfs functions. Debugfs functions never return NULL so this error handling will never trigger. (Historically debugfs functions used to return a mix of NULL and error pointers but it was eventually deemed too complicated for something which wasn't intended to be used in normal situations). Delete all the error handling.

2020-08-22memory: brcmstb_dpfe: fix array index out of boundsMarkus Mayer
We would overrun the error_text array if we hit a TIMEOUT condition, because we were using the error code "ETIMEDOUT" (which is 110) as an array index. We fix the problem by correcting the array index and by providing a function to retrieve error messages rather than accessing the array directly. The function includes a bounds check that prevents the array from being overrun.

The GPMC_SET_ONE_CD_MAX macro uses return statement and variable 'cs' coming from called scope. This is not a good practice. Also checkpatch complained: WARNING: Macros with flow control statements should be avoided ERROR: Macros starting with if should be enclosed by a do - while loop to avoid possible if/else logic defects Since GPMC_SET_ONE_CD_MAX macro just calls one function, it can be open coded.

2020-07-30memory: samsung: exynos5422-dmc: Add module param to control IRQ modeLukasz Luba
The driver can operate in two modes relaying on devfreq monitoring mechanism which periodically checks the device status or it can use interrupts when they are provided by loaded Device Tree. The newly introduced module parameter can be used to choose between devfreq monitoring and internal interrupts without modifying the Device Tree. It also sets devfreq monitoring as default when the parameter is not set (also the case for default when the driver is not built as a module).

Enabling the JZ4780_NEMC driver makes sense only for specific hardware - the Ingenic SoC architecture. It is not an essential driver for the SoC support so do not enable it by default.

2020-07-28memory: jz4780_nemc: Only request IO memory the driver will usePaul Cercueil
The driver only uses the registers up to offset 0x54. Since the EFUSE registers are in the middle of the NEMC registers, we only request the registers we will use for now - that way the EFUSE driver can probe too.

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/drivers Memory controller drivers for v5.9 The drivers/memory directory with memory controller drivers, over the last days grew in numbers but lacked any coordinated care. The generic part (device tree helpers) were pulled in through various trees, depending on driver needs. The patchset is a first try to improve code quality of memory controller drivers. Mostly these are non-intrusive fixes for GCC, checkpatch or sparse warnings. This also fixes missing SPDX tags or improves generic code quality (whitespace, const correctness). Last commit appoints also Krzysztof Kozlowski as a maintainer. * tag 'memory-controller-drv-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (22 commits) MAINTAINERS: Add Krzysztof Kozlowski as maintainer of memory controllers memory: samsung: exynos-srom: Describe the Kconfig entry memory: Describe the MEMORY Kconfig entry memory: da8xx-ddrctl: Remove unused 'node' variable memory: fsl_ifc: Fix whitespace issues memory: pl172: Add GPLv2 SPDX license header memory: omap-gpmc: Fix whitespace issue memory: omap-gpmc: Include <linux/sizes.h> for SZ_16M memory: mtk-smi: Add argument to function pointer definition memory: brcmstb_dpfe: Remove unneeded braces memory: brcmstb_dpfe: Constify the contents of string memory: ti-emif-pm: Fix cast to iomem pointer memory: ti-aemif: Rename SS to SSTROBE to avoid name conflicts memory: emif: Silence platform_get_irq() error in driver memory: emif: Fix whitespace coding style violations memory: emif: Put constant in comparison on the right side memory: emif-asm-offsets: Add GPLv2 SPDX license header memory: of: Remove unneeded extern from function declarations memory: of: Correct indentation memory: of: Remove __func__ in device related messages ...
