* clk: Move clock code in dev/clkEmmanuel Vadot2024-01-101-1/+1
| | | | | | | | | | | We've removed kernel option EXT_RESOURCES almost two years ago. While it was ok to have some code under a common 'extres' subdirectory at first, we now have a lot of consumer of it and we made it mandatory so no need to have it under a cryptic name.

* if_cgem: Rewrite clock partEmmanuel Vadot2023-09-181-32/+86
| | | | | | | | | | | | | - pclk and hclk are mandatory so always try to get them. Don't make it fatal if it fails as some platform (like Zynq) don't have a proper clock driver. - Always use pclk for the reference clock. - Try to get all the possible clocks and enable them.

* cgem: support SGMII PHY connection modeMilan Obuch2022-04-122-1/+15
| | | | | | | | | | | | | | | | | | As the PolarFire SoC needs SGMII to connect the PHY, check the 'phy-mode' property of device tree node for ethernet and act on it appropriately. Add the compatible strings for the PolarFire SoC device tree. 'microchip,mpfs-mss-gem" is not officially documented but has been observed in the available firmware for this platform, so it is included for now. Also, fix a typo in if_cgem_hw.h.

| | | | | | | | | | | | | Note that currently Linux's device tree uses the FU540's compatible string, as does upstream U-Boot, but the U-Boot shipped with the board based on an older patch series has the correct FU740 name.

* cgem: improve usage of busdma(9) KPIMitchell Horne2021-02-181-8/+4
| | | | | | | | | | | | | | | BUS_DMA_NOCACHE should only be used when one needs to guarantee the created mapping has uncached memory attributes, usually as a result of buggy hardware. Normal use cases should pass BUS_DMA_COHERENT, to create an appropriate mapping based on the flags passed to bus_dma_tag_create(). This should have no functional change, since the DMA tags in this driver are created without the BUS_DMA_COHERENT flag.

| | | | | | | | | | | | | | | 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=326255

Since we still don't have a general clock API that lets a SoC-independant driver manipulate its own clocks, this change includes a weak reference to a routine named cgem_set_ref_clk(). The default implementation is a no-op; SoC-specific code can provide an implementation that actually changes the speed.
