* MIPS: qemu-malta: use 320 MHz input clock for CP0 clocksourceAntony Pavlov2023-11-011-0/+20
| | | | | | | | | | | | | | | | | | | | | Modern qemu uses 24Kf CPU at 320 MHz for malta board. By default arch/mips/lib/csrc-r4k.c clocksource driver relies on CPU running at 200 MHz and CP0 timer runs at the half of CPU clock that is 100 MHz. As a result the `sleep 15` command runs for only 9 seconds on qemu-malta. Setting CPU clock to 320 MHz in the qemu-malta.dts file fixes the problem. See these qemu commits for details: eea1f5bac6f hw/mips/malta: Set CPU frequency to 320 MHz a7519f2b39b mips: malta/boston: replace cpu_model with cpu_type Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Link: https://lore.barebox.org/20231030223619.344784-1-antonynpavlov@gmail.com Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* MIPS: dts: ath79: ar9331: use path references when extending nodesAhmad Fatoum2023-02-222-17/+11
| | | | | | | | | | LED heartbeat already broke, because upstream renamed the node name. Fix that and let's use references, so we get errors if an upstream DT update breaks our usage.

* Treewide: Reference environment partitions by phandleSascha Hauer2022-10-197-14/+14
| | | | | | | | | | Where possible reference the environment partitions directly by phandle instead of referencing the physical device and describing the partition by "partname:xxx". This is one step to deprecate the "partname:xxx" binding. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | kbuild: gen-dtb-s: use Makefile.lib instead of duplicating cmd_lzoAhmad Fatoum2022-07-141-1/+1
|/ | | | | | | | | | | | | | We call lzop in two places: in gen-dtb-s to generate a compressed device tree symbol and in Makefile.lib, which is used everywhere else. Replace the duplication in gen-dtb-s by compressing the DT outside with the existing cmd_lzo command. This will come in handy later when extending gen-dtb-s to support multiple compression formats. No functional change intended.

* kbuild: remove obj-dtb-y, pbl-dtb-y, lwl-dtb-y syntaxMasahiro Yamada2020-05-201-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The embedded DTBs are compiled by the chain of pattern rules as follows: %.dts -> %.dtb -> %.dtb.S -> %.dtb.o for barebox proper %.dts -> %.dtb -> %.dtb.S -> %.dtb.pbl.o for pbl Barebox introduced {obj,pbl,lwl}-dtb-y syntax to put the intermediate files into extra-y. The purposes of doing so were: [1] prevent GNU Make from deleting the intermediate files [2] include .*.cmd files In contrast, Linux does not use a special syntax for embedding DTBs into the kernel. For example, as you see in arch/sh/boot/dts/Makefile of Linux 5.6, obj-y += <basename>.dtb.o ... just works. This is because scripts/Kbuild.include specifies .SECONDARY to cater to [1], and scripts/Makefile.build adds the intermediates to 'targets' to deal with [2]. Barebox had already imported the same code from Linux, so you can use obj-y instead of obj-dtb-y, like Linux. pbl-dtb-y and lwl-dtb-y are barebox-specific cases, so I added the %.dtb.pbl.o pattern to intermediate_targets. Going forward, please use obj-y, pbl-y, or lwl-y. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* MIPS: net: ag71xx/ar9331: partially sync network support with upstreamOleksij Rempel2019-10-143-15/+8
| | | | | | | | | | | | | Ethernet support for ar9331 is upstream now. So, drop every thing what is provided by upstream devicetree and rename compatible in the driver. barebox network driver will need more work to be upstream compliant. For example we should not request or touch the gmac register directly. Since currently it is not clear how this should be implemented, patch the upstream dts with reg-names = "ge0", "gmac".
