ath79: add support for PISEN WMB001N Specifications: - SoC: AR9341 - RAM: 64M - Flash: 16M - Ethernet: 1 * FE port - WiFi: ar934x-wmac - Sound: WM8918 DAC 1 * 3.5mm headphone jack 2 * RCA connectors for speakers 1 * SPDIF out - USB: 1 * USB2.0 port Flash instruction: Upload generated factory image via vendor's web interface. Notes: A. Audio stuff: 1. Since AR934x, all pins for peripheral blocks can be mapped to any available GPIOs. We currently don't have a PCM/I2S driver for AR934x so pinmux for i2s and SPDIF are bound to i2c gpio node. This should be moved into I2S node when a PCM/I2S driver is available. 2. The i2c-gpio node is for WM8918. DT binding for it can't be added currently due to a missing clock from I2S PLL. B. Factory image: Image contains a image header and a tar.gz archive. 1. Header: A 288 byte header that has nothing to do with appended tarball. Format: 0x0-0x7 and 0x18-0x1F: magic values 0x20: Model number string 0xFC: Action string. It's either "update" or "backup" 0x11C: A 1 byte checksum. It's XOR result of 0x8-0x11B Firmware doesn't care about the rest of the header as long as checksum result is correct. The same header is used for backup and update routines so the magic values and model number can be obtained by generating a backup bin and grab values from it. 2. Tarball: It contains two files named uImage and rootfs, which will be flashed into corresponding mtd partition. Writing a special utility that can only output a fixed binary blob is overkill so factory image header is placed under image/bin instead. C. LED The wifi led has "Wi-Fi" marked on the case but vendor's firmware used it as system status indicator. I did the same in this device support patch. D. Firmware Factory u-boot is built without 'savenv' support so it's impossible to change kernel offset. A 2MB kernel partition won't be enough in the future. OKLI loader is used here to migrate this problem: 1. add OKLI image magic support into uImage parser. 2. build an OKLI loader, compress it with lzma and add a normal uImage header. 3. flash the loader to where the original kernel supposed to be. 4. create a uImage firmware using OKLI loader. 5. flash the created firmware to where rootfs supposed to be. By doing so, u-boot will start OKLI loader, which will then load the actual kernel at 0x20000. The kernel partition is 2MB, which is too much for our loader. To save this space, "mtd-concat" is used here: 1. create a 64K (1 erase block) partition for OKLI loader and create another partition with the left space. 2. concatenate rootfs and this partition into a virtual flash. 3. use the virtual flash for firmware partition. Currently OKLI loader is flashed with factory image only. sysupgrade won't replace it. Since it only has one function and it works for several years, its unlikely to have some bugs that requires a replacement. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

ath79: remove model name from LED labels 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: add support for PISEN WMB001N Specifications: - SoC: AR9341 - RAM: 64M - Flash: 16M - Ethernet: 1 * FE port - WiFi: ar934x-wmac - Sound: WM8918 DAC 1 * 3.5mm headphone jack 2 * RCA connectors for speakers 1 * SPDIF out - USB: 1 * USB2.0 port Flash instruction: Upload generated factory image via vendor's web interface. Notes: A. Audio stuff: 1. Since AR934x, all pins for peripheral blocks can be mapped to any available GPIOs. We currently don't have a PCM/I2S driver for AR934x so pinmux for i2s and SPDIF are bound to i2c gpio node. This should be moved into I2S node when a PCM/I2S driver is available. 2. The i2c-gpio node is for WM8918. DT binding for it can't be added currently due to a missing clock from I2S PLL. B. Factory image: Image contains a image header and a tar.gz archive. 1. Header: A 288 byte header that has nothing to do with appended tarball. Format: 0x0-0x7 and 0x18-0x1F: magic values 0x20: Model number string 0xFC: Action string. It's either "update" or "backup" 0x11C: A 1 byte checksum. It's XOR result of 0x8-0x11B Firmware doesn't care about the rest of the header as long as checksum result is correct. The same header is used for backup and update routines so the magic values and model number can be obtained by generating a backup bin and grab values from it. 2. Tarball: It contains two files named uImage and rootfs, which will be flashed into corresponding mtd partition. Writing a special utility that can only output a fixed binary blob is overkill so factory image header is placed under image/bin instead. C. LED The wifi led has "Wi-Fi" marked on the case but vendor's firmware used it as system status indicator. I did the same in this device support patch. D. Firmware Factory u-boot is built without 'savenv' support so it's impossible to change kernel offset. A 2MB kernel partition won't be enough in the future. OKLI loader is used here to migrate this problem: 1. add OKLI image magic support into uImage parser. 2. build an OKLI loader, compress it with lzma and add a normal uImage header. 3. flash the loader to where the original kernel supposed to be. 4. create a uImage firmware using OKLI loader. 5. flash the created firmware to where rootfs supposed to be. By doing so, u-boot will start OKLI loader, which will then load the actual kernel at 0x20000. The kernel partition is 2MB, which is too much for our loader. To save this space, "mtd-concat" is used here: 1. create a 64K (1 erase block) partition for OKLI loader and create another partition with the left space. 2. concatenate rootfs and this partition into a virtual flash. 3. use the virtual flash for firmware partition. Currently OKLI loader is flashed with factory image only. sysupgrade won't replace it. Since it only has one function and it works for several years, its unlikely to have some bugs that requires a replacement. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

ath79: remove model name from LED labels 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.
