2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini

2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
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.

2023-04-11i2c: fsl_i2c: fix m68k transfertsAngelo Dureghello
This driver is actually used for powerpc and m68k/ColdFire. On ColdFire SoC's, interrupt flag get not set if IIEN flag (mbcr bit6, interrupt enabled) is not set appropriately before each transfert. As a result, the transfert hangs forever waiting for IIEN. This patch set IIEN before each transfert, while considering this fix as not harming powerpc arch.

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

This converts the following to Kconfig: CONFIG_SYS_IMMR We do this by consolidating the SYS_IMMR options we have and providing defaults. We also, in the few places where M68K was also sharing code with these platforms, define it within the file to CONFIG_SYS_MBAR to match usage. This should be cleaned up longer term.

2021-02-21dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIOIgor Opaniuk
Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise.

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
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>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2016-08-12fdt: allow fdtdec_get_addr_size_*() to translate addressesStephen Warren
Some code may want to read reg values from DT, but from nodes that aren't associated with DM devices, so using dev_get_addr_index() isn't appropriate. In this case, fdtdec_get_addr_size_*() are the functions to use. However, "translation" (via the chain of ranges properties in parent nodes) may still be desirable. Add a function parameter to request that, and implement it. Update all call sites to default to the original behaviour.

2014-11-23linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada
U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings.

2014-04-29drivers/i2c/fsl_i2c: modify i2c_read to handle multi-byte writeShaveta Leekha
Most of the I2C slaves support accesses in the typical style that is : read/write series of bytes at particular address offset. These transactions look like:" (1) START:Address:Tx:Offset:RESTART:Address[0..4]:Tx/Rx:data[0..n]:STOP" However there are certain devices which support accesses in terms of the transactions as follows: (2) "START:Address:Tx:Txdata[0..n1]:Clock_stretching: RESTART:Address:Rx:data[0..n2]" Here Txdata is typically a command and some associated data, similarly Rxdata could be command status plus some data received as a response to the command sent. Type (1) transactions are currently supportd in the i2c driver using i2c_read and i2c_write APIs. I2C EEPROMs, RTC, etc fall in this category. To handle type (2) along with type (1) transactions, i2c_read() function has been modified.

2013-08-20fsl_i2c: add workaround for the erratum I2C A004447Chunhe Lan
This workaround is for the erratum I2C A004447. Device reference manual provides a scheme that allows the I2C master controller to generate nine SCL pulses, which enable an I2C slave device that held SDA low to release SDA. However, due to this erratum, this scheme no longer works. In addition, when I2C is used as a source of the PBL, the state machine is not able to recover. At the same time, delete the reduplicative definition of SVR_VER and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16 bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro instead of hard-code value 0x10, 0x11 and 0x20. The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one version of platform has this I2C errata. So enable this errata by IS_SVR_REV(svr, maj, min) function.
