2024-08-09i2c: samsung: Support platforms other than EXYNOS4 and EXYNOS5David Virag
Newer Samsung SoCs (including newer Exynos, ExynosAuto, Google Tensor) still use these IPs, or slightly newer versions of it. Make these drivers available on these platforms by guarding EXYNOS4/EXYNOS5 specific code behind their configs, and using CCF for clocks on other platforms. Tested S3C I2C driver on Exynos7885. This along with extended clock driver should enable S3C I2C on Exynos850.

2020-12-18dm: Avoid accessing seq directlySimon Glass

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>
2020-07-25treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()Masahiro Yamada
Use the _ptr suffixed variant instead of casting. Also, convert it to dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE. One curious part is an error check like follows in drivers/watchdog/omap_wdt.c: priv->regs = (struct wd_timer *)devfdt_get_addr(dev); if (!priv->regs) return -EINVAL; devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error. So, this code does not catch any error in DT parsing. dev_read_addr_ptr() returns NULL on error, so this error check will work.

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>

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.

2015-08-05exynos: i2c: Tidy up the driver model codeSimon Glass
The existing driver model implementation uses the old non-driver-model code to operate, but has become impossibly tangled as a result. The actual algorithm is quite simple. Also the normal-speed and high-speed buses are quite different and it doesn't seem that useful to put them in the same driver. Finally, there is a bug which breaks communication with the Maxim sound codec and may cause problems with other device. Rewrite the driver model code for normal-speed operation so that it is easier to understand, and fix the bug. Add a TODO to split the drivers.

2013-10-17exynos: i2c: Change FDT bus setup code to enumerate ports correctlySimon Glass
At present the i2c ports are enumerated in a strange way - the fdtdec_find_aliases_for_id() function is used, but then the ID returned is ignored and the ports are renumbered. The effect is the same provided that the device tree has the ports in the same order, or uses aliases, and has no gaps, but it is not correct. Adjust the code to use the function as intended. This will allows device tree aliases to change the device order if required. As a result, the i2c_busses variable is dropped. We can't be sure that there are no 'holes' in the list of buses, so must check the whole array. Note: it seems that non-FDT operation is now broken in this drive and will need to be reinstated for upstream.

This patch corrects the following issues 1) Write the correct M/T Stop value to I2CSTAT after i2c write. According to the spec, after finish the data transmission, we should write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA). 2) Not split the write to I2CSTAT into 2 steps in i2c read. According to the spec, we should write the combined M/R Start value to I2CSTAT after setting the slave address to I2CDS 3) Fix the mistake of making an equality check to an assignment. In the case of I2C write with the zero-length address, while tranfering the data, it should be an equality check (==) instead of an assignment (=).
