memory: samsung: Rename Exynos to lowercase

2020-01-07T19:46:32+00:00

Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.

"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

memory: samsung: exynos5422-dmc: Add support for interrupt from performance counters

2019-10-02T17:37:37+00:00

Introduce a new interrupt driven mechanism for managing speed of the
memory controller. The interrupts are generated due to performance
counters overflow. The performance counters might track memory reads,
writes, transfers, page misses, etc. In the basic algorithm tracking
read transfers and calculating memory pressure should be enough to skip
polling mode in devfreq.

memory: samsung: exynos5422-dmc: Fix kfree() of devm-allocated memory and missing static

2019-10-01T18:28:38+00:00

Fix issues captured by static checkers: use of kfree() on
resource-managed memory and missing 'static' in the private function.

Fixes Smatch warning:
    drivers/memory/samsung/exynos5422-dmc.c:272
        exynos5_init_freq_table() warn: passing devm_ allocated variable to kfree. 'dmc->opp'

Fixes Sparse warning:
    drivers/memory/samsung/exynos5422-dmc.c:736:1:
        warning: symbol 'exynos5_dmc_align_init_freq' was not declared.

memory: Add DMC driver for Exynos5422

2019-10-01T18:28:38+00:00

Add driver for Exynos5422 Dynamic Memory Controller.  The driver
provides support for dynamic frequency and voltage scaling for DMC and
DRAM.  It supports changing timings of DRAM running with different
frequency.  There is also an algorithm to calculate timings based on
memory description provided in DT.

memory: Convert to using %pOFn instead of device_node.name

2018-11-27T16:54:39+00:00

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

memory: samsung: exynos-srom: make it explicitly non-modular

2016-06-20T07:48:59+00:00

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.
