since the phy associated with it is on the carrier board and not on
the SoM;
* add the reset pin associated to each phy;
* separate the ethernet, mdio and reset pins of each fec so that they

* add clock properties to the phy nodes since they are connected to the

The previous version of am335x-fb.c contained the functionalities of two
drivers that this patch has split. It was a video type driver that used
the same registration compatible string that now registers a panel type
driver. The proof of this is that two compatible strings were referred
to within the same driver.
There are now two drivers, each with its own compatible string,
functions and API.
Furthermore, the panel driver, in addition to decoding the display
timings, is now also able to manage the backlight.

The __of_translate_address routine translates an address from the
device tree into a CPU physical address. A note in the description of
the routine explains that the crossing of any level with
since inherited from IBM. This does not happen for Texas Instruments, or
at least for the beaglebone device tree. Without this patch, in fact,
the translation into physical addresses of the registers contained in the
am33xx-clocks.dtsi nodes would not be possible. They all have a parent
with #size-cells = <0>.
The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation
possible even in the case of crossing levels with #size-cells = <0>.
The patch acts conservatively on address translation, except for
removing a check within the of_translate_one function in the
drivers/core/of_addr.c file:
+
ranges = of_get_property(parent, rprop, &rlen);
- if (ranges == NULL && !of_empty_ranges_quirk(parent)) {
- debug("no ranges; cannot translate\n");
- return 1;
- }
if (ranges == NULL || rlen == 0) {
offset = of_read_number(addr, na);
memset(addr, 0, pna * 4);
debug("empty ranges; 1:1 translation\n");
There are two reasons:
1 The function of_empty_ranges_quirk always returns false, invalidating
the following if statement in case of null ranges. Therefore one of
the two checks is useless.
2 The implementation of the of_translate_one function found in the
common/fdt_support.c file has removed this check while keeping the one
about the 1:1 translation.
The patch adds a test and modifies a check for the correctness of an
address in the case of enabling translation also for zero size cells.
The added test checks translations of addresses generated by nodes of
a device tree similar to those you can find in the files am33xx.dtsi
and am33xx-clocks.dtsi for which the patch was created.
The patch was also tested on a beaglebone black board. The addresses
generated for the registers of the loaded drivers are those specified
by the AM335x reference manual.

Up till this commit passing NULL as input parameter was allowed, but not
handled properly. When a NULL parameter was passed to the function a data
abort was raised.

It returns the rate which will be set if you ask clk_set_rate() to set
that rate. It provides a way to query exactly what rate you'll get if
you call clk_set_rate() with that same argument.
So essentially, clk_round_rate() and clk_set_rate() are equivalent
except the former does not modify the clock hardware in any way.

There have been several changes to the am33xx.dtsi, so this patch
re-syncs it with Linux.
Let's add proper interconnect hierarchy for l4 interconnect instances
with the related ti-sysc interconnect module data as documented in
Documentation/devicetree/bindings/bus/ti-sysc.txt of the Linux kernel.
With l4 interconnect hierarchy and ti-sysc interconnect target module
data in place, we can simply move all the related child devices to their
proper location and enable probing using ti-sysc.
The am33xx-clock.dtsi file is the same as that of the Linux kernel,
except for the reg property of the node l4-wkup-clkctrl@0.
As for the am33xx.dtsi file, all the devices with drivers not yet
implemented and those I was able to test with this patch have been moved
to am33xx-l4.dtsi. In case of any regressions, problem devices can be
reverted by moving them back and removing the related interconnect
target module node.

We can handle the sysc interconnect target module in a generic way for
many TI SoCs. Initially let's just enable domain clocks before the
children are probed.
The code is loosely based on the drivers/bus/ti-sysc.c of the Linux
kernel version 5.9-rc7.
