memory: bt1-l2-ctl: Remove not-going-to-be-supported code for Baikal SoC

2026-02-26T07:28:15+00:00

As noticed in the discussion [1] the Baikal SoC and platforms are not going to be finalized, hence remove stale code.

memory: bt1-l2-ctl: replace scnprintf() with sysfs_emit()

2025-05-07T05:44:13+00:00

Documentation/filesystems/sysfs.rst mentions that show() should only use sysfs_emit() or sysfs_emit_at() when formating the value to be returned to user space. So replace scnprintf() with sysfs_emit(). Signed-off-by: Salah Triki Link: https://lore.kernel.org/r/aBkw_p9GkH2fm2UJ@pc Signed-off-by: Krzysztof Kozlowski

memory: remove MODULE_LICENSE in non-modules

2023-03-09T14:20:50+00:00

Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

Add blank lines to improve code readability. No functional change. Signed-off-by: Krzysztof Kozlowski

memory: Add Baikal-T1 L2-cache Control Block driver

2020-05-28T12:17:41+00:00

Baikal-T1 SoC provides a way to tune the MIPS P5600 CM2 L2-cache performance up. It can be done by changing the L2-RAM Data/Tag/WS latencies in a dedicated register exposed by the system controller. The driver added by this commit provides a dts properties-based and sysfs-based interface for it. The device DT node is supposed to be a child of Baikal-T1 System Controller node.
