2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
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.

2020-12-14dm: 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>
2020-11-26mmc: atmel-sdhci: fix the clk_enable call in case of no opsEugen Hristev1-1/+2
If the clock driver does not offer a clk_enable ops, then the system will return -ENOSYS. The clk_enable works with CCF (common clock framework). Some clocks in some cases (like the generic clock for some products: sama5d2) do not have the clk_enable primitive, and in this case probing of the driver will fail. This patch changes the behavior to return an error in case there is really an error, and not a missing primitive. If the clock driver does not have an enable primitive, most likely clocks are always enabled or enabled in the set_rate primitives.

2020-09-25mmc: atmel-sdhci: do not check clk_set_rate return valueEugen Hristev1-3/+1
clk_set_rate will return rate in case of success and zero in case of error, however it can also return -ev, but it's an ulong function. To avoid any issues, disregard the return value of this call. In case this call actually fails, nothing much we can do anyway, but we can at least try with the previous values (or DT assigned-clocks) Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>

2020-07-25treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()Masahiro Yamada1-1/+1
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 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>
2017-11-30mmc: atmel_sdhci: not on capabilities to set gck rateLudovic Desroches1-10/+2
The capabilities have default values which doesn't reflect the reality when it concerns the base clock and the mul value. Use a fixe rate for the gck. 240 MHz is an arbitrary choice, it is a multiple of the maximum SD clock frequency handle by the controller and it allows to get a 400 kHz clock for the card initialisation.

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.

2017-01-23mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier1-2/+5
The sdhci controller assumes that the base clock frequency is fully supported by the peripheral and doesn't support hardware limitations. The Linux kernel distinguishes between base clock (max_clk) of the host controller and maximum frequency (f_max) of the card interface.
