2021-01-22ARM: dts: qcom: replace status value "ok" by "okay"Adrian Schmutzler24-128/+128
While the DT parser recognizes "ok" as a valid value for the "status" property, it is actually mentioned nowhere. Use the proper value "okay" instead, as done in the majority of files already.

2021-01-22ARM: dts: qcom: add additional DT labels in qcom-ipq8064.dtsiAdrian Schmutzler1-12/+11
This adds some additional DT labels which are handy when referring to the nodes in derived DTS(I) files. It will also make the definitions more consistent, e.g. by adding gsbi2_serial and gsbi5_serial where we previously "only" had gsbi4_serial defined. While at it, add missing spaces after some DT labels and remove one useless empty line.

2021-01-20ARM: remove u300 platformArnd Bergmann2-466/+0
The Ericsson U300 platform was one of two ARM929 based SoC platforms for mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP into ST-Ericsson, the other one being the ST Nomadik. The platform was not widely adopted in Linux based systems and was replaced with the far superior ST-Ericsson U8500 in 2011, but Linus Walleij kept maintaining the code for the whole time. Linus continues to use the Nomadik machine, but decided to drop u300 from the kernel as part of this year's spring cleaning. Thanks for having maintained it all these years.

2021-01-20ARM: remove tango platformArnd Bergmann4-285/+0
The smp8758 (tango4) SoC was the last generation of set-top-box chips to come out of Sigma Designs, and support was added by Marc Gonzalez and Måns Rullgård between 2015 and 2017, before the company went out of business and the products were abandoned. The chip is used in some set-top-boxes such as the Popcorn Hour A-500, which could have seen some adoption by hobbyists. This has not happened in the past four years, and support for the more widely used MIPS based SoCs was never merged at all. Thanks to Marc and Måns for maintaining for the past years even after the death of the platform.

2021-01-20ARM: remove zte zx platformArnd Bergmann3-191/+0
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

2021-01-20ARM: remove sirf prima2/atlas platformsArnd Bergmann7-3841/+0
The SiRF Prima2 and Atlas platform code was contributed by Cambridge Silicon Radio (CSR) after aquiring the original SiRF company, and maintained by Barry Song. CSR was subsequently acquired by Qualcomm, who no longer have an interest in maintaining the SoC platform but instead have released more recent SoCs for the same market in the Snapdragon family. As Barry is no longer working for the company, nobody else there wants to maintain it, and there are no third-party users, the best way forward seems to be to completely remove it. Thanks to Barry for maintaining the platform for the past ten years.

2021-01-18ARM: dts: imx6qdl-sr-som: fix some cubox-i platformsRussell King1-2/+10
The PHY address bit 2 is configured by the LED pin. Attaching a LED to this pin is not sufficient to guarantee this configuration pin is correctly read. This leads to some platforms having their PHY at address 0 and others at address 4. If there is no phy-handle specified, the FEC driver will scan the PHY bus for a PHY and use that. Consequently, adding the DT configuration of the PHY and the phy properties to the FEC driver broke some boards. Fix this by removing the phy-handle property, and listing two PHY entries for both possible PHY addresses, so that the DT configuration for the PHY can be found by the PHY driver.

The KSZ8081 datasheet states that the tsr parameter (Stable supply voltage (VDDIO, VDDA_3.3) to reset high) to be 10ms minimum and "After the de-assertion of reset, wait a minimum of 100 µs before starting programming on the MIIM (MDC/MDIO) interface." Describe these parameters in the devicetree. Signed-off-by: Fabio Estevam <festevam@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2021-01-18ARM: dts: imx6ul-14x14-evk: Enable the GPIO expanderFabio Estevam1-0/+3
Currently the 74LV595PW GPIO expander is not functional because its OE pin is not driven low. Make it funcional by passing the 'enable-gpios' property inside the GPIO expander node. After putting the OE pin in low state, the outputs of the 74LV595PW all go low. The two KSZ8081 Ethernet PHYs reset lines are driven from the the GPIO expander and as they remain low, this causes the Ethernet PHYs not to be detected. There is one solution to this problem as suggested by Andrew Lunn: "Some devices will respond to MDIO while held in reset, some don't. If your PHYs don't you need to add a compatible of the form ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$ with the PHY ID. The PHY will then be probed, independent of if it can be found on the bus or not, and that probing will enable the GPIO." So pass the "ethernet-phy-id0022.1560" for the KSZ8081 PHYs so that they both can be functional after 74LV595PW is activated.

2021-01-15ARM: dts: ux500: Reserve memory carveoutsLinus Walleij4-1/+112
The Ux500 platforms have some memory carveouts set aside for communicating with the modem and for the initial secure software (ISSW). These areas are protected by the memory controller and will result in an external abort if accessed like common read/write memory. On the legacy boot loaders, these were set aside by using cmdline arguments such as this: mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M mem=638M@385M Reserve the relevant areas in the device tree instead. The "mali", "hwmem", "mem_ram_console" and the trailing 1MB at the end of the memory reservations in the list are not relevant for the upstream kernel as these are nowadays replaced with upstream technologies such as CMA. The modem and ISSW reservations are necessary. This was manifested in a bug that surfaced in response to commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()") which changes the behaviour of memory allocations in such a way that the platform will sooner run into these dangerous areas, with "Unhandled fault: imprecise external abort (0xc06) at 0xb6fd83dc" or similar: the real reason turns out to be that the PTE is pointing right into one of the reserved memory areas. We were just lucky until now. We need to augment the DB8500 and DB8520 SoCs similarly and also create a new include for the DB9500 used in the Snowball since this does not have a modem and thus does not need the modem memory reservation, albeit it needs the ISSW reservation.

I didn't touch this code since it served as a platform to introduce ARMv7-M support to Linux. The only known machine that runs Linux has only 4 MiB of RAM (that originally only exists to hold the display's framebuffer). There are no known users and no further use foreseeable, so drop the code.
