* ath79: enable UART in SoC DTSI filesAdrian Schmutzler2021-02-241-5/+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 Schmutzler2020-10-021-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: correctly define WiFi switch for TL-WR841ND v8Adrian Schmutzler2020-07-211-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | The TL-WR841ND v8 feature a WiFi switch instead of a button. This adds the corresponding input-type to prevent booting into failsafe regularly. This has been defined correctly in ar71xx, but was overlooked when migrating to ath79. In contrast, the TL-WR842ND v2, which has the key set up as switch in ar71xx, actually has a button. The TL-MR3420 v2 has a button as well and is set up correctly for both targets. (Information based on TP-Link user guide) Note: While looking into this, I found that support PR for TL-MR3420 v2 switched reset button to ACTIVE_HIGH. However, the other two device still use ACTIVE_LOW. This seems strange, but I cannot verify it lacking the affected devices.

* ath79: add gpio4 pinmux on TL-WR841N/ND v8, WR842N v2, MR3420 v2Adrian Schmutzler2020-02-181-4/+8
| | | | | | | | | | | | | | | | | | | | | This adds a pinmux to the shared DTSI for TP-Link TL-WR841N/ND v8, TL-WR842N v2 and TL-MR3420 v2. It is supposed to be the equivalent of: /* config gpio4 as normal gpio function */ ath79_gpio_output_select(TL_MR3420V2_GPIO_USB_POWER,AR934X_GPIO_OUT_GPIO); This allows to enable USB power on these devices. While at it, move the jtag_disable_pins to &gpio node and remove the redundant status=okay there. Tested on TP-Link TL-WR842N v2.

* treewide: remove dts-v1 identifier from DTSI filesAdrian Schmutzler2019-12-081-1/+0
| | | | | | | | | | | | | | | | The "/dts-v1/;" identifier is supposed to be put once at the beginning of a device tree file. Thus, it makes no sense to provide it a second time in to-be-included DTSI files. This removes the identifier from all DTSI files in /target/linux. Most of the DTS files in OpenWrt do contain the "/dts-v1/;". It is missing for most of the following targets, though: mvebu, ipq806x, mpc85xx, ipq40xx This does not touch ipq806x for now, as the bump to 4.19 is close.

* ath79: DTS file style update and harmonizationAdrian Schmutzler2019-11-061-5/+5
| | | | | | | | | | | | | | | | | | This applies several style adjustments that have been requested in recent reviews to older DTS files. Despite making the code base more consistent, this will also help to reduce review time when DTSes are copy/pasted. Applied changes: - Rename gpio-keys/gpio-leds to keys/leds - Remove node labels that are not used - Use label property for partitions - Prefix led node labels with "led_" - Remove redundant includes - Harmonize new lines after status property - Several smaller style fixes Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ath79: provide label MAC addressAdrian Schmutzler2019-09-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the label MAC address for several devices in ath79. Some devices require setting the MAC address in 02_network: For the following devices, the netif device can be linked in device tree, but the MAC address cannot be read: - alfa-network,ap121f - avm,fritz300e - ubnt-xm devices For the following devices, label MAC address is tied to lan or wan, so no node to link to exists in device tree: - adtran,bsap1800-v2 - adtran,bsap1840 - dlink,dir-842-c1/-c2/-c3 - engenius,ecb1750 - iodata,etg3-r - iodata,wn-ac1167dgr - iodata,wn-ac1600dgr - iodata,wn-ac1600dgr2 - iodata,wn-ag300dgr - nec,wg800hp - nec,wg1200cr - trendnet,tew-823dru Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ath79: create DTSI for ar9341 TP-Link devicesAdrian Schmutzler2019-08-171-0/+114
This patch creates a shared DTSI for the TP-Link devices based on ar9341 as those share a lot of definitions. While at it, change from gpio-keys-polled to gpio-keys, remove unused pll-data and remove some inherited stuff, too. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
