Add compat strings for all the flavors of GIC this driver should support.
Also allow the driver to attach to ofwbus as well as simplebus, some FDT
data puts the root interrupt controller on the root bus.
Add a common routine for parsing FDT data describing an ARM GIC interrupt.
Use gic_decode_fdt() rather than a local routine to parse fdt interrupt
properties. Move fdt_pic_table and fdt_fixup_table into imx6_machdep.c,
which means imx6 doesn't need imx_common.c anymore.
The private peripheral interrupts start at offset 16, not 0. Also, use
names rather than inline mystery constants for these offsets.
- Add a basic iomux driver for imx6.
- Implement the same public interface in imx51 and imx6 iomux
- The iomux driver is no longer optional, remove it from kernel configs.
- Implement the imx_iomux_get/set_gpr() interface for imx6.
- Stop setting the iomux device status to disabled, now that we have a driver.
o Enable GPIO device driver for i.MX6.
It was originally written for i.MX5 and compatible with newer chip.
o Extend device tree information
o style(9) fixes
o Rename gpio driver file.
Add a function to get the frequency of the AHB bus. Another stopgap
function until we have full clock support for imx6.
The imx5x and imx6 chips have an onboard IOMUX device which also contains a
few "general purpose registers" whose values control chip behavior in ways
that have nothing to do with IO pin mux control. Define a simple API that
other soc-specific code can use to read and write the registers, and provide
the imx51 implementation of them.
Fix a typo.
- Remove #include <machine/frame.h>.
- Add gpio parse routines according to sys/boot/fdt/dts/bindings-gpio.txt.
- Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.
- Rename platform_gpio_init to be SoC specific, and make it static as it's
only called from this file.
This is mostly catching up on some old MFCs that were done before this file
existed in the 10 branch.
Fixes and enhancements for the if_cgem driver...
- miibus fixes as suggested by Yonghyeon Pyun.
- enable VLAN MTU support.
- fix a few WITNESS complaints in cgem_attach().
- have cgem_attach() properly init the ifnet struct before calling
mii_attach() to fix panic when using e1000phy.
- fix ethernet address changing.
- fix transmit queue overflow handling.
- tweak receive queue handling to reduce receive overflows.
- bring out MAC statistic counters to sysctls.
- add e1000phy to config file.
- implement receive hang work-around described in reference guide.
- change device name from if_cgem to cgem to be consistent with other
interfaces.
Fix the Zedboard/Zynq ethernet driver to handle media speed changes so
that it can connect to switches at speeds other than 1gb.
Add a driver for the TI watchdog.
The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need
to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.
In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.

In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo).
The EABI unwind info requires a .fnend for every .fnstart, and newer
binutils will complain about seeing two .fnstart in a row. This change
allows newer tools to compile our code.
Do not generate unwind info in asm functions if _STANDALONE is defined.
The .fnend op causes the assembler to emit RELOC references to unwind
support functions that don't exist in libstand.

Fix the handling of MMU type in the AP entry code. The ARM_MMU_V6/V7
symbols are always #defined to 0 or 1, so use #if SYM not #if defined(SYM).
Also, it helps if you include the header file that defines the symbols.

MFC r269339:
In the implementation of the new function pmap_unwire(), the call to
MOEA64_PVO_TO_PTE() must be performed before any changes are made to the

Rename vt_generate_vga_palette() to vt_generate_cons_palette() and
change it to build a palette where the color index is the same than in
terminal escape codes, not the VGA index. That's what TCHAR_CREATE()
uses and passes to vt(4).
The main differences between both orders are:
o Blue and red are swapped (1 <-> 4)
o Yellow and cyan are swapped (3 <-> 6)
The problem remained unnoticed, because the RGB bit indexes passed to
vt_generate_vga_palette() were reversed. This inversion was cancelled
by the colors inversions in the generated palette. For instance, red
(0xff0000) and blue (0x0000ff) have bytes in opposite order, but were
swapped in the palette. But after changing the value of blue (see last
paragraph), the modified color was in fact the red one.
While here, tune the palette to better match console colors and improve
the readability (especially the dark blue).
This is an MFC of r269783 and r269791.
FreeBSD, historically, has always used 8-bit addresses for i2c devices
(7-bit device address << 1), always leaving the room for the read/write
bit.
This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.
Also, update the PMIC i2c address on beaglebone* DTS files to match the
new address scheme.
Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).
Discussed with: ian
MFC r267834:
Clarify the expected usage of I2C 7-bit slave addresses on ioctl(2)
interface.
While here add the cross reference to iic(4) on iicbus(4).

Ignore IIC_ENOADDR from iicbus_reset() as it only means we have a
master-only controller.
This fixes the iic bus scan with i2c(8) (on supported controllers).
Tested with gpioiic(4).
MFC r267009:
Remove the unnecessary i2c slave address assignment.
The ti_i2c controller only works in the master mode and the i2c address
passed on iicbus_reset() is used to set the controller slave address when
operating as an i2c slave (which isn't currently supported).
When talking to a slave, the slave address is correctly provided to
ti_i2c_tranfer().
Configure the analog input 7 which, on BBB, is connected to the 3V3B rail

Export two new settings for the AM335x PWM, the clock prescaler (clkdiv)
and the actual PWM frequency.
Enforce the maximum value for the period sysctl.
The frequency systcl now allows the direct setting of the PWM frequency
(it will try to find the better clkdiv and period for a given frequency,
i.e. the ones that will give the better PWM resolution).
This allows the use lower frequencies on the PWM. Without changing the
clock prescaler the minimum PWM frequency was 1.52kHz.
PWM frequencies checked with an osciloscope.
PWM output tested with some R/C servos at 50Hz.
Cache the imx6 SoC type in a static var so that it only has to be figured
out by sniffing hardware registers once.
Add a missing clock register definition.
Set ofwbus and simplebus to attach during BUS_PASS_BUS.
Define names that drivers can use to adjust their position relative to
other drivers within a BUS_PASS
Adjust ofwbus and simplebus to attach at BUS_PASS_ORDER_MIDDLE, so that
a platform can attach some other bus first if necessary.
Set the pl310 L2 cache driver to attach during the middle of BUS_PASS_CPU.
Attach arm generic interrupt and timer drivers in the middle of
BUS_PASS_INTERRUPT and BUS_PASS_TIMER, respectively.
Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass
device attachment on arm platforms. If this is defined, nexus attaches
early in BUS_PASS_BUS, and other busses and devices attach later, in the
pass number they are set up for. Without it defined, nexus attaches in
BUS_PASS_DEFAULT and thus so does everything else, which is status quo.
Add 64-bit atomic ops for armv6, and also for armv4 only in kernel code.
Use the new ops in the cddl code (and avoid defining functions with the
same names locally).
r269214, r269215, r269216, r269217, r269221:
busdma-v6 improvements, primarily:
- Allocate the temporary segments array per-map rather than per-tag.
- Avoid needlessly bouncing IO for mbufs and buffers allocated by
bus_dmamem_alloc() (in both situations we known they're allocated
on cacheline boundaries and don't need bouncing).
- Various minor reformatting and cleanups.
Fix C++ exception handling for ARM EABI.
Just the part of r264070 that creates the FBSD_1.4 namespace in libc
is hand-applied, and then r264082 which creates the Versions.def entry
is MFC'd.
Pending interrupt status is cleared by writing to the ISR, not the data reg.
Use named constant rather than '0' to access the reset controller register.
Map device memory using PTE_DEVICE attributes, and also ensure that the
shared flag is set on normal-memory mappings made via pmap_kenter() for SMP.
The "shared flag" part of this change isn't obvious from the diff, here's
the deal... by using the array of preformatted page table entry templates
instead of constructing the PTE from scratch, we automatically get the
right attribute bits set for both caching and shared.
Fix whitespace glitches.
