2022-12-06global: Move remaining CONFIG_SYS_* to CFG_SYS_*Tom Rini1-4/+4
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2020-12-14dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-1/+1
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass1-2/+2
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>
2020-08-22treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()Masahiro Yamada1-1/+1
When you enable CONFIG_OF_LIVE, you will end up with a lot of conversions. To help this tedious work, this commit converts devfdt_get_addr_ptr() to dev_read_addr_ptr() by coccinelle. I also removed redundant casts because dev_read_addr_ptr() returns an opaque pointer. To generate this commit, I ran the following semantic patch excluding include/dm/. <smpl> @@ type T; expression dev; @@ -(T *)devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) @@ expression dev; @@ -devfdt_get_addr_ptr(dev) +dev_read_addr_ptr(dev) </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

2017-08-17mmc: gen_atmel_mci: Fix wrong arguments used of bind()Wenyou.Yang@microchip.com1-22/+42

2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
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.

2015-11-02mmc: atmel: Fix clock configurationMarek Vasut1-0/+2
After silencing the prints which were generated when reconfiguring the clock of the SD/MMC bus, surprisingly, the driver stopped working such that every attempt to use the SD/MMC bus caused the CPU to get totally stuck hard. It turns out that the prints generated a short delay, which was necessary for the CPU to reconfigure the clock without getting stuck. Thus, this patch adds a short delay after the clock configuration instead. Signed-off-by: Marek Vasut <marex@denx.de> Reviewed-by: Andreas Bießmann <andreas.devel@googlemail.com>

This driver generates clearly debugging prints when changing clock speed, so silence those. Furthermore, the driver generates further prints in case a command fails to complete. The later case woud be useful, but for eMMC, command 8 can fail and it's not an error but a part of the specification. Thus, make this debug() as well.

2014-03-24mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou1-17/+26
The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
