* ath79: enable UART in SoC DTSI filesAdrian Schmutzler2021-02-241-4/+0
| | | | | | | | | | | | | | | The uart node is enabled on all devices except one (GL-USB150 *). Thus, let's not have a few hundred nodes to enable it, but do not disable it in the first place. Where the majority of devices is using it, also move the serial0 alias to the DTSI. *) Since GL-USB150 even defines serial0 alias, the missing uart is probably just a mistake. Anyway, disable it for now so this patch stays cosmetic. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ath79: remove model name from LED labelsAdrian Schmutzler2020-10-021-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we request LED labels in OpenWrt to follow the scheme modelname:color:function However, specifying the modelname at the beginning is actually entirely useless for the devices we support in OpenWrt. On the contrary, having this part actually introduces inconvenience in several aspects: - We need to ensure/check consistency with the DTS compatible - We have various exceptions where not the model name is used, but the vendor name (like tp-link), which is hard to track and justify even for core-developers - Having model-based components will not allow to share identical LED definitions in DTSI files - The inconsistency in what's used for the model part complicates several scripts, e.g. board.d/01_leds or LED migrations from ar71xx where this was even more messy Apart from our needs, upstream has deprecated the label property entirely and introduced new properties to specify color and function properties separately. However, the implementation does not appear to be ready and probably won't become ready and/or match our requirements in the foreseeable future. However, the limitation of generic LEDs to color and function properties follows the same idea pointed out above. Generic LEDs will get names like "green:status" or "red:indicator" then, and if a "devicename" is prepended, it will be the one of an internal device, like "phy1:amber:status". With this patch, we move into the same direction, and just drop the boardname from the LED labels. This allows to consolidate a few definitions in DTSI files (will be much more on ramips), and to drop a few migrations compared to ar71xx that just changed the boardname. But mainly, it will liberate us from a completely useless subject to take care of for device support review and maintenance. To also drop the boardname from existing configurations, a simple migration routine is added unconditionally. Although this seems unfamiliar at first look, a quick check in kernel for the arm/arm64 dts files revealed that while 1033 lines have labels with three parts *:*:*, still 284 actually use a two-part labelling *:*, and thus is also acceptable and not even rare there.

* ath79: move dts-v1 statement to ath79.dtsiAdrian Schmutzler2020-09-251-2/+2
| | | | | | | | | | | | | | | | | | | The "/dts-v1/;" identifier is supposed to be present once at the top of a device tree file after the includes have been processed. In ath79, we therefore requested to have in the DTS files so far, and omit it in the DTSI files. However, essentially the syntax of the parent ath79.dtsi file already determines the DTS version, so putting it into the DTS files is just a useless repetition. Consequently, this patch puts the dts-v1 statement into the parent ath79.dtsi, which is (indirectly) included by all DTS files. All other occurences are removed. Since the dts-v1 statement needs to be before any other definitions, this also moves the includes to make sure the ath79.dtsi or its descendants are always included first.

* ath79: drop and consolidate redundant chosen/bootargsAdrian Schmutzler2020-06-251-4/+0
| | | | | | | | | | | | | | In ath79, for several SoCs the console bootargs are defined to the very same value in every device's DTS. Consolidate these definitions in the SoC dtsi files and drop further redundant definitions elsewhere. The only device without any bootargs set has been OpenMesh OM5P-AC V2. This will now inherit the setting from qca955x.dtsi Note that while this tidies up master a lot, it might develop into a frequent pitfall for backports.

* ath79: add support for MikroTik RouterBOARD 493G (rb4xx series)Christopher Hill2020-06-151-0/+180
This patch adds support for the MikroTik RouterBOARD RB493G, ported from the ar71xx target. See https://routerboard.com/RB493G for details Specification: - SoC Qualcomm Atheros AR7161 - RAM: 256 MiB - Storage: 128MiB NAND - Ethernet: 9x 1000/100/10 Mbps - USB 1x 2.0 / 1.0 type A - PCIe: 3x Mini slot - MicroSD slot Working: - Board/system detection - Ethernet - SPI - NAND - LEDs - USB - Sysupgrade Enabled (but untested due to lack of hardware): - PCIe - ath79_pci_irq struct has the slot/pin/IRQ mappings if needed Installation methods: - tftp boot initramfs image, scp then flash via "sysupgrade -n" - nand boot existing OpenWrt, scp then flash via "sysupgrade -n" Notes: - initramfs image will not work if uncompressed image size over ~8.5Mb - The "rb4xx" drivers have been enabled Signed-off-by: Christopher Hill <ch6574@gmail.com>
