* Move Ti AM335x to dev/extres/clk framework.Michal Meloun2020-07-301-14/+68
| | | | | | | | | | | | | | | | | Re-implement clocks for these SoC by using now standard extres/clk framework. This is necessary for future expansion of these. The new implementation is (due to the size of the patch) only the initial (minimum) version. It will be updated/expanded with a subsequent set of particular patches. This patch is also not tested on OMAP4 based boards (BeagleBone), so all possible issues should be (and will be) fixed by ASAP once identified.

* sys/arm: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326258

* INTRNG - redefine struct intr_map_data to avoid headers pollution. EachSvatopluk Kraus2016-05-051-3/+7
| | | | | | | | | | | | | | | | | | | struct associated with some type defined in enum intr_map_data_type must have struct intr_map_data on the top of its own definition now. When such structs are used, correct type and size must be filled in. There are three such structs defined in sys/intr.h now. Their definitions should be moved to corresponding headers by follow-up commits. While this change was propagated to all INTRNG like PICs, pic_map_intr() method implementations were corrected on some places. For this specific method, it's ensured by a caller that the 'data' argument passed to this method is never NULL. Also, the return error values were standardized there.

* Set output pin initial value based on pin's pinmux pullup/pulldown setupOleksandr Tymoshenko2015-08-011-2/+8
| | | | | | | | | | | | | Some of FDT blobs for AM335x-based devices use pinmux pullup/pulldown flag to setup initial GPIO ouputp value, e.g. 4DCAPE-43 sets LCD DATAEN signal this way. It works for Linux because Linux driver does not enforce pin direction until after it's requested by consumer. So input with pullup flag set acts as output with GPIO_HIGH value Reviewed by: loos Notes: svn path=/head/; revision=286165

It should make easier to adopt platform code to new revisions of hardware and to use DTS overlays for various Beaglebone extensions (shields/capes). Original dts filenames were not changed, they're now wrappers over dts files provided by TI. So make sure you update .dtb files on your devices as part of kernel update GPIO addressing was changed: instead of one global /dev/gpioc0 there are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25 on /dev/gpioc3 On Pandaboard serial console devices was changed from /dev/ttyu0 to /dev/ttyu2 so you'll have to update /etc/ttys to get login prompt on serial port in multiuser mode.

* - Fix the setup of interrupts for banks 2 and 3 on AM335x.Luiz Otavio O Souza2014-04-051-16/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | On AM335x each one of the four GPIO banks has two physical interrupt lines, so we now allocate resources and setup our interrupt handler for all the (8) available interrupts. On OMAP3 and OMAP4 there is only one interrupt for each GPIO bank (6 banks, 6 interrupts), but there are two set of registers where the first one is used to setup the delivery of interrupts to the MPU and the second set, setup the delivery of interrupts to the DSP. On AM335x, each set of registers controls each one of the interrupt lines. - Remove nonexistent registers for OMAP4 and AM335x, replace their use with the correct ones for these SoCs. - Remove stray whitespace. Based on OMAP3, OMAP4 and AM335x TRMs. Tested on Beaglebone-black. Notes: svn path=/head/; revision=264153

Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings. Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper. Notes: svn path=/head/; revision=261410
