2025-07-02MIPS: ralink: add missing header includeMieczyslaw Nalewaj
Add the missing header "asm/time.h" which defines the function prototypes of get_c0_perfcount_int() and get_c0_compare_int(). This patch fixes the following build warnings: arch/mips/ralink/irq.c:86:5: error: no previous prototype for 'get_c0_perfcount_int' [-Werror=missing-prototypes] 86 | int get_c0_perfcount_int(void) | ^~~~~~~~~~~~~~~~~~~~ arch/mips/ralink/irq.c:92:14: error: no previous prototype for 'get_c0_compare_int' [-Werror=missing-prototypes] 92 | unsigned int get_c0_compare_int(void) | ^~~~~~~~~~~~~~~~~~ Signed-off-by: Mieczyslaw Nalewaj <namiltd@yahoo.com> Signed-off-by: Shiji Yang <yangshiji66@outlook.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
2025-05-16MIPS: Switch to irq_domain_create_*()Jiri Slaby (SUSE)
irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2024-11-13clocksource/drivers/ralink: Add Ralink System Tick Counter driverSergio Paracuellos
System Tick Counter is present on Ralink SoCs RT3352 and MT7620. This driver has been in 'arch/mips/ralink' directory since the beggining of Ralink architecture support. However, it can be moved into a more proper place in 'drivers/clocksource'. Hence add it here adding also support for compile test targets and reducing LOC in architecture code folder.

2023-07-28MIPS: More explicit DT include clean-upsRob Herring
A couple more clean-ups in the MIPS code. The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Recently, A new clock and reset controller driver has been introduced to the ralink mips target[1]. It provides proper system control and adds more SoC specific compatible strings. In order to better initialize CPUs, this patch removes the outdated "ralink,mt7620a-sysc" and add all dt-binding documented compatible strings to the system controller match table.

2023-06-21mips: ralink: get cpu rate from new driver codeSergio Paracuellos
At very early stage on boot, there is a need to set 'mips_hpt_frequency'. This timer frequency is a half of the CPU frequency. To get clocks properly set we need to call to 'of_clk_init()' and properly get cpu clock frequency afterwards. Depending on the SoC, CPU clock index and compatible differs, so use them to get the proper clock frm the clock provider. Hence, adapt code to be aligned with new clock driver.

2023-06-21mips: ralink: remove reset related codeSergio Paracuellos
A proper clock driver for ralink SoCs has been added. This driver is also a reset provider for the SoC. Hence there is no need to have reset related code in 'arch/mips/ralink' folder anymore. The only code that remains is the one related with mips_reboot_setup where a PCI reset is performed. We maintain this because I cannot test old ralink board with PCI to be sure all works if we remove also this code.

With CONFIG_SLUB=y, following commit 6edf2576a6cc ("mm/slub: enable debugging memory wasting of kmalloc") mt7621 failed to boot very early, without showing any console messages. This exposed the pre-existing bug of mt7621.c using kzalloc before normal memory management was available. Prior to this slub change, there existed the unintended protection against "kmem_cache *s" being NULL as slab_pre_alloc_hook() happened to return NULL and bailed out of slab_alloc_node(). This allowed mt7621 prom_soc_init to fail in the soc_dev_init kzalloc, but continue booting without the SOC_BUS driver device registered.

Loads of tiny cleanups for almost all staging drivers in here, nothing major at all. Highlights include: - remove the ashmem Android driver. It is long-dead and if there are any legacy userspace applications still using it, the Android kernel images will maintain it, the community shouldn't care about it anymore - wfx wifi driver major cleanups. Should be ready to merge out of staging soon, and will coordinate with the wifi maintainers after -rc1 is out - major cleanups and unwinding of the layers of the r8188eu driver. It's amazing just how many unneeded layers of abstraction is in there, just when we think it's done, another is found... - lots of tiny coding style cleanups in many other staging drivers.

2022-02-16MIPS: ralink: mt7621: do memory detection on KSEG1Chuanhong Guo
It's reported that current memory detection code occasionally detects larger memory under some bootloaders. Current memory detection code tests whether address space wraps around on KSEG0, which is unreliable because it's cached. Rewrite memory size detection to perform the same test on KSEG1 instead. While at it, this patch also does the following two things: 1. use a fixed pattern instead of a random function pointer as the magic value. 2. add an additional memory write and a second comparison as part of the test to prevent possible smaller memory detection result due to leftover values in memory.
