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: i2c: allow disabling driver model in SPL At present if U-Boot proper uses driver model for I2C, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. This patch introduces a separate Kconfig symbols for enabling DM_I2C and DM_I2C_GPIO support in SPL. This will also help to get away from dirty workarounds to achieve non-DM I2C support for SPL, which is currently used in some board header files like: ifdef CONFIG_SPL_BUILD undef CONFIG_DM_I2C endif Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de> Signed-off-by: Igor Opaniuk <igor.opaniuk@foundries.io> Reviewed-by: Tom Rini <trini@konsulko.com>

Convert CONFIG_SYS_I2C_LEGACY to Kconfig and add CONFIG_[ST]PL_SYS_I2C_LEGACY First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig. Next, as you cannot have SYS_I2C_LEGACY and DM_I2C at the same time, introduce CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only in SPL. Finally, for some PowerPC cases we also need CONFIG_TPL_SYS_I2C_LEGACY support. Convert all of the existing users to one or more symbols. Signed-off-by: Tom Rini <trini@konsulko.com>

i2c: xiic: Add Xilinx AXI I2C driver Add Xilinx AXI I2C controller driver based on the Linux i2c-xiic driver. This driver is stripped of all the IRQ handling and uses pure polling, yet tries to retain most of the structure of the Linux driver to make backporting of fixes easy. Note that the IP has a known limitation on 255 bytes read and write, according to xilinx this is still being worked on [1].

i2c: add Tegra186 BPMP driver On Tegra186, some I2C controllers are directly controlled by the main CPU, whereas others are controlled by the BPMP, and can only be accessed by the main CPU via IPC requests to the BPMP.

dm: i2c: Add support for multiplexed I2C buses Add a new I2C_MUX uclass. Devices in this class can multiplex between several I2C buses, selecting them one at a time for use by the system. The multiplexing mechanism is left to the driver to decide - it may be controlled by GPIOs, for example. The uclass supports only two methods: select() and deselect(). The current mux state is expected to be stored in the mux itself since it is the only thing that knows how to make things work. The mux can record the current state and then avoid switching unless it is necessary. So select() can be skipped if the mux is already in the correct state. Also deselect() can be made a nop if required. Signed-off-by: Simon Glass <sjg@chromium.org>

Link failure with CONFIG_SPL and CONFIG_I2C_MUX_PCA954x Fix for the case of a U-Boot configuration with CONFIG_SPL, CONFIG_I2C_MUX, CONFIG_I2C_MUX_PCA954x, no CONFIG_SPL_DM and no CONFIG_SPL_I2C_MUX. Without this fix linking of pca954x fails because dm_write_i2c does not exist because CONFIG_SPL_DM is not defined.
