Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"" When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

gpio: rockchip: Use gpio alias id as gpio bank id The U-Boot driver try to base the gpio bank id on the gpio-ranges prop and fall back to base the bank id on the node name. However, the linux driver try to base the bank id on the gpio alias id and fall back on node order. This can cause issues when SoC DT is synced from linux and gpioX@ nodes has been renamed to gpio@ and gpio-ranges or a SoC specific alias has not been assigned. Try to use the gpio alias id as first fallback when a gpio-ranges prop is missing to ease sync of updated SoC DT. Keep the current fallback on node name as a third fallback to not affect any existing unsynced DT.

gpio: rockchip: Add support for RK3568 and RK3588 banks The GPIO V2 controller on RK3568 and RK3588 works very similar to prior generation, main difference is the use of a write mask in the upper 16 bits and register address offset have changed. GPIO_VER_ID is a new register at 0x0078 that is used to determine when the driver should use new or old register offsets and values. Earlier generation return 0x0 from this offset.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

gpio: rockchip: Add support for RK3568 and RK3588 banks The GPIO V2 controller on RK3568 and RK3588 works very similar to prior generation, main difference is the use of a write mask in the upper 16 bits and register address offset have changed. GPIO_VER_ID is a new register at 0x0078 that is used to determine when the driver should use new or old register offsets and values. Earlier generation return 0x0 from this offset.

drivers: rename drivers to match compatible string When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

dm: Rename dev_addr..() functions These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

gpio: add Tegra186 GPIO driver Tegra186's GPIO controller register layout is significantly different from previous chips, so add a new driver for it. In fact, there are two different GPIO controllers in Tegra186 that share a similar register layout, but very different port mapping. This driver covers both. The DT binding is already present in the Linux kernel (in linux-next via the Tegra tree so far).

dm: treewide: Rename auto_alloc_size members to be shorter This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org> |

However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

dm: Rename dev_addr..() functions These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

gpio: add Tegra186 GPIO driver Tegra186's GPIO controller register layout is significantly different from previous chips, so add a new driver for it. In fact, there are two different GPIO controllers in Tegra186 that share a similar register layout, but very different port mapping. This driver covers both. The DT binding is already present in the Linux kernel (in linux-next via the Tegra tree so far).
