2021-11-26arm64: zynqmp: Fix serial compatible stringMichal Simek
[ Upstream commit 812fa2f0e9d33564bd0131a69750e0d165f4c82a ] Based on commit 65a2c14d4f00 ("dt-bindings: serial: convert Cadence UART bindings to YAML") compatible string should look like differently that's why fix it to be aligned with dt binding.

2021-11-26arm64: zynqmp: Do not duplicate flash partition label propertyAmit Kumar Mahapatra
[ Upstream commit 167721a5909f867f8c18c8e78ea58e705ad9bbd4 ] In kernel 5.4, support has been added for reading MTD devices via the nvmem API. For this the mtd devices are registered as read-only NVMEM providers under sysfs with the same name as the flash partition label property. So if flash partition label property of multiple flash devices are identical then the second mtd device fails to get registered as a NVMEM provider. This patch fixes the issue by having different label property for different flashes.

2020-10-29arm64: dts: zynqmp: Remove additional compatible string for i2c IPsMichal Simek
[ Upstream commit 35292518cb0a626fcdcabf739aed75060a018ab5 ] DT binding permits only one compatible string which was decribed in past by commit 63cab195bf49 ("i2c: removed work arounds in i2c driver for Zynq Ultrascale+ MPSoC"). The commit aea37006e183 ("dt-bindings: i2c: cadence: Migrate i2c-cadence documentation to YAML") has converted binding to yaml and the following issues is reported: ...: i2c@ff030000: compatible: Additional items are not allowed ('cdns,i2c-r1p10' was unexpected) From schema: .../Documentation/devicetree/bindings/i2c/cdns,i2c-r1p10.yaml fds ...: i2c@ff030000: compatible: ['cdns,i2c-r1p14', 'cdns,i2c-r1p10'] is too long The commit c415f9e8304a ("ARM64: zynqmp: Fix i2c node's compatible string") has added the second compatible string but without removing origin one.

2019-01-25arm64: dts: zcu100-revC: Give wifi some time after power-onJan Kiszka
Somewhere along recent changes to power control of the wl1831, power-on became very unreliable on the Ultra96, failing like this: wl1271_sdio: probe of mmc2:0001:1 failed with error -16 wl1271_sdio: probe of mmc2:0001:2 failed with error -16 After playing with some dt parameters and comparing to other users of this chip, it turned out we need some power-on delay to make things stable again. In contrast to those other users which define 200 ms, Ultra96 is already happy with 10 ms.

2018-08-24arm64: dts: Fix various entry-method properties to reflect documentationAmit Kucheria
The idle-states binding documentation[1] mentions that the 'entry-method' property is required on 64-bit platforms and must be set to "psci". commit a13f18f59d26 ("Documentation: arm: Fix typo in the idle-states bindings examples") attempted to fix this earlier but clearly more is needed. Fix the cpu-capacity.txt documentation that uses the incorrect value so we don't get copy-paste errors like these. Clarify the language in idle-states.txt by removing the reference to the psci bindings that might be causing this confusion. Finally, fix devicetrees of various boards to reflect current documentation.

2017-11-09kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.libMasahiro Yamada
If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile. It could be a race problem when building DTBS in parallel. Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor sub-directories, so this broke when Broadcom added one more hierarchy in arch/arm64/boot/dts/broadcom/<soc>/. One idea to fix the issues in a clean way is to move DTB handling to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y natively, so it should not hurt to do so. Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is enabled. All clutter things in Makefiles go away. As a bonus clean-up, I also removed dts-dirs. Just use subdir-y directly to traverse sub-directories.

2017-08-21arm64: zynqmp: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.
