jmcneill | #define<tab> for consistency with the rest of the file

| 1.4 | 27-Apr-2022 |
skrll | Sync with OpenBSD
- Use subpage feature
- Catch up with new device tree bindings
- Skip locked DARTs
- Use bypass mode for USB3 DARTs
Other changes from me
- Sprinkle BITS(3)
- Improve interrupt error handling
|
| 1.3 | 06-Sep-2021 |
jmcneill | Instead of requiring drivers to be explicit about their device memory
mapping requirements, move this decision into the fdt layer. This
introduces a new MD function, fdtbus_bus_tag_create, which is responsible
for returning per-node bus_space handles.
|
| 1.2 | 04-Sep-2021 |
jmcneill | Use fdt_iommu instead of calling appledart directly from applepcie
|
| 1.1 | 30-Aug-2021 |
jmcneill | Add initial support for Apple M1.
Currently supported devices:
- Interrupt controller
- IOMMU
- PCIe (USB3 and ethernet)
- Reboot via watchdog
- Framebuffer console
|
| 1.3 | 16-Sep-2025 |
thorpej | As with ACPI, perform the fdtbus_register_i2c_controller() in a centralized
location.
|
| 1.2 | 16-Sep-2025 |
thorpej | Garbage-collect fdtbus_attach_i2cbus(); the regular iicbus_attach() is
sufficient now.
|
| 1.1 | 10-May-2022 |
skrll | Add a driver for the Apple M1 I2C controller. From OpenBSD.
|
| 1.9 | 28-Jun-2022 |
jmcneill | appleintc: update ci_cpl in pic_set_priority callback
|
| 1.8 | 02-May-2022 |
ryo | fix non-MULTIPROCESSOR build
|
| 1.7 | 28-Mar-2022 |
riastradh | arm/apple: Use container_of, not bespoke offsetof arithmetic.
Better type-safety this way.
|
| 1.6 | 26-Nov-2021 |
skrll | Mask the bottom 5 bits in the standard pic way. NFC.
|
| 1.5 | 26-Nov-2021 |
skrll | no need to shout
|
| 1.4 | 31-Oct-2021 |
skrll | Rework Arm (32bit and 64bit) AP startup so that cpu_hatch doesn't sleep.
The AP initialisation code in cpu_init_secondary_processor will read and
initialise the required system registers and state for the BP to attach
and report.
Rework the interrupt handler code for this new sequence. Thankfully,
this removes a bunch of code for bcm2836mp.
The VFP detection handler on <= armv7 relies on the global undefined
handler being in place until the BP attaches vfp. That is, after the
APs have been spun up.
gicv3_its.c has a serialisation issue which is protected against in
the gicv3_its_cpu_init, which is called from cpu_hatch, with a spin
lock. The serialisation issue needs addressing more completely.
Tested on RPI3, Apple M1, QEMU, and lx2k
Fixes PR port-arm/56264:
diagnostic assertion "l->l_stat == LSONPROC" failed on RPI3

| 1.3 | 16-Oct-2021 |
ryo | fix non-MULTIPROCESSOR build
Build tested only.

This tag is still used for early console attachment.

| 1.3 | 02-Sep-2021 |
jmcneill | apple: derive CPU speed from mpidr_el1
According to https://github.com/AsahiLinux/docs/wiki/HW%3AARM-System-Registers,
MPIDR_EL1 Aff2 determines whether a core is an efficiency or performance
core. Replace the compat data table with code that uses the aff2 value
for fake DMIPS/MHz value, to hopefully maintain compatibility with future
cores.
|
| 1.2 | 01-Sep-2021 |

performance cores.

thorpej | Step towards modularizing the Flattened Device Tree code.
Define attributes for each of the specific device bindings: clock,
dai, dma, gpio, i2c, iommu, mbox, mmc_pwrseq, phy, power, power domain,
pwm, regulator, reset controller, spi, system controller, pin
controller. Include these support files only if either a provider
or consumer with one of these attributes is present in the kernel
config.
Add the necessary attributes to the device / attach declarations for
each provider and consumer.
There are some bindings that are consumed by generic code (iommu, pinctrl,
power, power domain). Provide weak stubs for these routines to handle
situations where there is no provider.
No actual code changed; NFCI.
